Thresher Sharks in Malapascua: A Guide to Responsible Shark Diving

With their long, graceful tails and unmistakable shape, thresher sharks are among the most fascinating sharks a diver can encounter.

Malapascua Island in northern Cebu is internationally known for reliable sightings of pelagic thresher sharks. These normally deep-water animals regularly rise toward shallower cleaning stations, giving divers a rare opportunity to observe them in their natural environment.

Today, many of Malapascua’s thresher shark encounters take place at Kimud Shoal, an offshore underwater plateau reached by an early-morning boat trip from the island.

At Sea Explorers Malapascua, we organize guided dives to Kimud Shoal and other sites around Malapascua. Every trip depends on weather, sea conditions, local regulations, diver experience, and site availability.

Here is what you should know before diving with thresher sharks in Malapascua.

What Is a Thresher Shark?

Thresher sharks belong to the genus Alopias. They are easily recognized by the unusually long upper section of their tail fin, which may be almost as long as the rest of the shark’s body.

Their streamlined shape, pointed snout, relatively small mouth, and large tail are suited to life in open water.

Although their appearance may seem dramatic, thresher sharks are generally shy and cautious around divers. They usually keep their distance and may swim away when approached, chased, or disturbed.

For divers, the best encounter often comes from remaining calm, maintaining good buoyancy, and allowing the shark to choose how close it wants to approach.

Why Do Thresher Sharks Have Such Long Tails?

The long tail is more than a distinctive physical feature. Thresher sharks use it as part of their hunting strategy.

They may swim rapidly toward schools of fish and use powerful movements of the tail to stun or disorient their prey. Once the fish are easier to catch, the shark can turn and feed.

This hunting method allows the shark to target schooling fish efficiently.

Thresher sharks mainly feed on small pelagic fish and squid. Their diet may include sardines, mackerel, anchovies, lanternfish, juvenile tuna, and other schooling species.

The Three Species of Thresher Shark

Three recognized species of thresher shark are found in oceans around the world.

Pelagic Thresher Shark

Scientific name: Alopias pelagicus

The pelagic thresher is the species most strongly associated with Malapascua’s cleaning stations.

It is the smallest of the three thresher shark species and is commonly found in tropical and subtropical waters of the Indo-Pacific.

Pelagic threshers have a streamlined body and a blue-grey or darker upper surface. Their pale underside helps create countershading, making them less visible from above and below.

Bigeye Thresher Shark

Scientific name: Alopias superciliosus

The bigeye thresher has very large eyes adapted for seeing in deeper, darker water.

It also has noticeable grooves extending from the top of the head toward the gill area. Its large eyes and deeper-water lifestyle distinguish it from the pelagic and common thresher.

Bigeye threshers are widely distributed in tropical and temperate seas.

Common Thresher Shark

Scientific name: Alopias vulpinus

The common thresher is the largest of the three species.

It is more commonly associated with temperate and subtropical waters, although its range is broad. It has a robust body and can grow considerably larger than the pelagic thresher.

While Malapascua is best known for pelagic thresher sharks, any wildlife identification should be made carefully. Sightings vary, and divers should avoid assuming the species based only on size or colour.

Where Do Thresher Sharks Live?

Thresher sharks are primarily open-ocean animals. They spend much of their time away from shallow coastal reefs and may move vertically through the water column.

Pelagic thresher sharks are found across tropical and subtropical areas of the Indian and Pacific Oceans.

Although they often live and hunt in deeper water, they may visit shallower offshore reefs and underwater plateaus. These locations can provide food, resting opportunities, or access to cleaning stations.

That behaviour makes Malapascua particularly special.

Why Are Thresher Sharks Seen in Malapascua?

Thresher sharks visit offshore cleaning stations around Malapascua.

At a cleaning station, small reef fish remove parasites, dead skin, and other material from the shark’s body. The shark may slow down, circle the area, or hold its position while cleaner fish work around its skin, gills, and mouth.

This is a natural relationship between the shark and the cleaner fish. The cleaner fish receive food, while the shark benefits from having parasites and unwanted material removed.

Divers may observe the sharks passing above the reef, circling in open water, or approaching known cleaning areas.

These encounters should always be treated as wildlife observations. The sharks are not fed, trained, or controlled, and sightings can never be absolutely guaranteed.

Kimud Shoal: Malapascua’s Main Thresher Shark Dive

Kimud Shoal has become one of the most important sites for thresher shark diving from Malapascua.

The site is an underwater plateau surrounded by deep water. Its upper sections begin at recreational diving depths before the slopes and walls descend much deeper.

Thresher sharks rise from the surrounding deep water and visit cleaning stations around the shoal. Divers normally position themselves at an appropriate distance and observe the blue water for approaching sharks.

Kimud Shoal may also offer encounters with schooling fish, tuna, reef fish, rays, and other pelagic animals. However, all wildlife encounters depend on natural behaviour and conditions on the day.

What to Expect on a Kimud Shoal Trip

Sea Explorers normally schedules Kimud Shoal as an early-morning trip.

A typical experience may include:

• An early meeting at the dive center
• Equipment preparation and checks
• A detailed site and safety briefing
• A boat journey of approximately 50 minutes
• One or more dives, depending on the scheduled trip
• Surface intervals on the boat
• A return to Malapascua later in the morning

Departure times and journey length can change due to weather, sea conditions, boat assignment, local regulations, and operational requirements.

Guests should confirm the current schedule directly with the Sea Explorers Malapascua team.

What Happened to Monad Shoal?

Monad Shoal played a major role in making Malapascua famous as a thresher shark destination.

For many years, divers travelled there before sunrise to observe thresher sharks visiting cleaning stations around the underwater plateau.

More recently, many of the regular sightings have been concentrated around Kimud Shoal. As a result, Kimud has become the main thresher shark trip for many Malapascua dive operators.

Monad Shoal remains an important part of the area’s diving history and may still be included in local schedules depending on current sightings, conditions, and dive-center planning.

Because marine animals move naturally, the most suitable location can change. Divers should rely on current local information rather than older articles that describe only Monad Shoal.

Current Diving Rules at Kimud Shoal

Kimud Shoal is now managed as a Marine Protected Area and Ecotourism Zone.

The rules are designed to protect the thresher sharks, their cleaning stations, and the surrounding reef. Requirements may be updated, so guests should always follow the latest instructions from local authorities and the Sea Explorers dive team.

Diver Experience Requirements

Current requirements include:

• Open Water Divers with fewer than 50 logged dives must dive with a dive professional.
• Open Water and Advanced Open Water Divers with fewer than 50 logged dives must complete a buoyancy workshop.
• Divers must demonstrate enough control to avoid touching the reef or disturbing marine life.

The dive center may recommend additional supervision or training based on a diver’s recent experience, buoyancy, certification, and comfort level.

Activities Not Allowed

The following activities are not permitted at Kimud Shoal:

• Discover Scuba Diving or try dives
• Open Water course training dives
• Snorkeling
• Freediving

Kimud Shoal should therefore not be presented as a site for first-time or uncertified divers.

New divers can complete their training at suitable local sites around Malapascua before working toward the experience required for Kimud Shoal.

Equipment Restrictions

The following items or practices are prohibited:

• Reef hooks
• Metal pointers or sticks
• Gloves, unless medically approved
• Touching the reef or seabed
• Collecting marine life
• Leaving unsecured hoses, gauges, or accessories hanging below the diver

Divers should prepare their equipment carefully before entering the water.

How to Behave Around Thresher Sharks

A responsible encounter gives the shark enough space to move naturally.

Maintain the Required Distance

Divers must remain at least five meters away from the sharks.

Do not swim directly toward a shark or attempt to block its path. The animal should always have enough space to approach, turn, or leave.

Do Not Chase the Sharks

Chasing a thresher shark may interrupt its natural behaviour and cause it to leave the cleaning station.

Remain calm, follow your guide, and allow the shark to determine the distance of the encounter.

Maintain Good Buoyancy

Stay under control and avoid resting on the reef or seabed.

Poor buoyancy can damage the cleaning station and create unnecessary movement or sediment. It can also distract other divers and disturb the sharks.

Avoid Sudden Movements

Move slowly and calmly.

Rapid finning, uncontrolled descents, and sudden approaches may cause a shy shark to change direction or swim away.

Keep Equipment Secured

Secure your alternate air source, pressure gauge, camera accessories, and other equipment.

Nothing should drag across the reef or hang below you.

Be Careful with Lights

Do not direct strong lights at thresher sharks.

Follow your guide’s instructions regarding video lights, photography equipment, and any current restrictions at the site.

Never Touch or Feed the Sharks

Thresher sharks at Kimud Shoal are wild animals.

They should never be touched, fed, attracted with bait, or manipulated for a photograph.

The goal is to observe natural behaviour with as little interference as possible.

What Certification Do You Need?

The appropriate certification depends on the planned depth, local rules, current conditions, and dive-center requirements.

Kimud Shoal is not suitable for Discover Scuba Diving participants or Open Water course training dives.

Certified Open Water Divers may be able to join under the required supervision and buoyancy conditions. However, additional training may make the experience more comfortable and enjoyable.

Useful courses may include:

• PADI Advanced Open Water Diver
• PADI Peak Performance Buoyancy
• PADI Enriched Air Nitrox
• Deep Diver training
• AWARE Shark and Ray Conservation
• A refresher or Back to the Water program

Certification alone does not always demonstrate recent experience or good buoyancy. Be honest with the dive center about your logged dives, date of your last dive, and confidence in open water.

Is Nitrox Recommended?

Enriched Air Nitrox may be recommended for some thresher shark dive profiles.

Nitrox contains a higher percentage of oxygen and a lower percentage of nitrogen than normal air. When used correctly, it may provide longer no-decompression limits at certain depths.

However, Nitrox does not automatically allow a diver to stay underwater without limits.

Divers must:

• Hold the appropriate Nitrox certification
• Personally analyze their cylinder
• Confirm the oxygen percentage
• Label or verify the cylinder correctly
• Set the gas on their dive computer
• Follow the maximum operating depth
• Monitor oxygen exposure and no-decompression limits
• Maintain enough breathing gas for the planned dive

Sea Explorers offers PADI Enriched Air Nitrox training for divers who want to learn how to use Nitrox properly.

Are Thresher Shark Sightings Guaranteed?

No wildlife encounter can be completely guaranteed.

Malapascua is known for reliable thresher shark sightings, but the sharks are wild animals. Their presence and behaviour may be influenced by currents, water temperature, visibility, food availability, human activity, and other natural factors.

A successful dive should not be measured only by how close a shark comes.

The chance to observe the cleaning station, reef, schooling fish, open-water environment, and responsible conservation practices is also part of the experience.

When sharks appear, enjoy the encounter without chasing them or competing with other divers for the closest position.

When Is the Best Time to Dive with Thresher Sharks?

Thresher shark diving is offered throughout much of the year in Malapascua.

However, weather, wind, visibility, currents, and sea conditions vary by season and from day to day.

Early-morning departures are commonly scheduled because the sharks often visit cleaning stations during the morning. Exact departure times may change according to local conditions and dive-center operations.

When planning your trip, allow several diving days rather than relying on one single scheduled shark dive. This gives you more flexibility if weather or sea conditions affect the trip.

It also gives you time to explore Malapascua’s other dive sites.

What Else Can You Dive in Malapascua?

Malapascua offers much more than thresher sharks.

Gato Island

Gato Island is known for underwater rock formations, reef life, sea snakes, white-tip reef sharks, macro animals, and a tunnel used by properly trained and guided divers when conditions allow.

The appropriate route depends on certification, experience, and conditions.

Local Macro Sites

Local sites around Malapascua may offer:

• Frogfish
• Seahorses
• Nudibranchs
• Ghost pipefish
• Crabs and shrimp
• Blue-ringed octopuses
• Mandarin fish

These dives are particularly rewarding for underwater photographers and divers who enjoy searching for small marine animals.

Reef and Wall Diving

Several local sites feature coral gardens, slopes, walls, and reef fish.

Some are suitable for newly certified divers, while others may have deeper sections or stronger currents.

Night Diving

Night dives reveal a different side of Malapascua’s marine life.

Mandarin fish, crustaceans, cephalopods, seahorses, and other nocturnal animals may appear after sunset.

Kalanggaman and Capitancillo

Longer day trips may be available to Kalanggaman Island or Capitancillo, depending on the schedule, weather, sea conditions, participation, and local regulations.

These trips combine island scenery with reef and wall diving.

How to Get to Malapascua

Malapascua is located off the northern tip of Cebu Island.

Most international and domestic visitors arrive through Mactan-Cebu International Airport.

A typical journey includes:

1. A private vehicle or public transport from Cebu or Mactan to Maya Port
2. A boat transfer from Maya to Malapascua Island
3. A short walk or local transfer to the resort and dive center

The drive from Cebu or Mactan to Maya normally takes approximately three to four hours, depending on traffic, road conditions, and stops.

The boat crossing generally takes around 30 to 40 minutes, depending on the vessel and sea conditions.

Transfer arrangements, departure points, port procedures, and schedules may change. Sea Explorers can help arrange transfers when requested in advance.

Contact Sea Explorers Philippines for current transfer information.

Where to Stay in Malapascua

Sea Explorers Malapascua is located beside Ocean Vida Beach & Dive Resort on Bounty Beach.

The beachfront location makes it convenient for divers to prepare for early departures and return to the resort after their dives.

Guests may also stay at Buena Vida Resort & Spa, a quieter sister property within walking distance of the beach and dive center.

Accommodation and diving packages depend on room availability, season, selected dive program, and number of nights.

What Should You Bring?

For an early-morning thresher shark trip, consider bringing:

• Certification card
• Logbook or digital dive history
• Dive computer
• Surface marker buoy, when required
• Appropriate exposure protection
• Reef-safe sun protection
• Water bottle
• Towel or light jacket
• Camera equipment only when your buoyancy is reliable
• Personal medication permitted for diving
• Any required proof of medical clearance

Divers using Nitrox should bring a computer that can be set to the analyzed oxygen percentage.

Ask the dive center which safety equipment is supplied and which items divers must carry personally.

Thresher Shark Conservation

Thresher sharks face pressure from commercial and small-scale fishing, accidental capture, habitat disturbance, and demand for shark meat and fins.

Their life history makes them particularly vulnerable. Like many large sharks, they grow slowly, mature relatively late, and produce a limited number of young.

Responsible tourism can help demonstrate that living sharks have long-term value to local communities.

Divers can support conservation by:

• Choosing responsible dive operators
• Following Marine Protected Area rules
• Avoiding shark products
• Reporting irresponsible wildlife interactions
• Maintaining excellent buoyancy
• Paying applicable environmental fees
• Sharing accurate information
• Supporting shark and marine-protection initiatives

The future of Malapascua’s thresher shark diving depends on protecting both the sharks and the cleaning stations they visit.
