A rarely seen megamouth shark (Megachasma pelagios) was recently spotted in east Africa. This marks the first time the species has been recorded in this region. The shark was found in a market in Zanzibar, being sold after capture.
Discovery of the Megamouth Shark in Zanzibar
The megamouth shark was discovered in Chole market on Pemba Island. This sighting is only the sixth ever off the coast of Africa. The shark was captured by an artisanal fishing vessel. It was sold for about $17.
Characteristics of the Megamouth Shark
The megamouth shark is known for its large mouth. It can reach up to 7 meters in length. Despite its size, it is a filter feeder. The species is rarely seen, suggesting it is likely solitary.

The megamouth was first discovered in 1976. It got tangled in a navy boat’s anchor chain in Hawaii. Since then, fewer than 280 megamouth sharks have been recorded worldwide. It is known for its tadpole-like shape and large mouth.
Megamouth Shark’s Global Presence
The megamouth shark is found all over the world. Despite its rarity, it is classified as a species of Least Concern. This suggests its numbers are higher than the recorded sightings. Fishing operations currently have minimal impact on the species.
Megamouth Shark in East Africa
This was the first megamouth shark recorded in east Africa. It extends the known range of the species. Previous sightings were in South Africa, Gabon, Liberia, Senegal, and Mauritania. These sightings occurred between 1995 and 2020.
Marine Biologists’ Research Efforts
Marine biologists analyze thousands of photos of dead sharks at landing sites. These include unwanted animals accidentally caught in fishing gear. Seeing the megamouth shark was a rare and significant event.
Implications of the Discovery
The discovery fills a gap in the known distribution of the megamouth shark. It contributes to understanding the species’ global range. Each new sighting adds valuable information. This helps piece together the megamouth shark’s life and habits.
Researching the Rare Megamouth Shark
Researching the megamouth shark is challenging due to its rarity. Scientists rely on sightings and accidental catches. The first pregnant megamouth shark was found in the Philippines in 2023. This confirmed that the species gives birth to live young.
Importance of Reporting Megamouth Sightings
It is crucial to report megamouth shark sightings. This can be done through nature conservation or government fishery departments. The Wildlife Conservation Society or the nearest aquarium can also be contacted. Sharing information helps build knowledge about this elusive species.
