Did you know?
Amazing Whale Shark Facts
Rhincodon typus
Its scientific name is Rhincodon typus, the only living species in its family.
A gentle filter feeder
Despite its enormous size, it filters plankton, fish eggs, and other small organisms from the water.
Spots like fingerprints
Its white spots and stripes form patterns unique to each individual, which researchers use to identify them.
Ocean travelers
Whale sharks live in tropical and warm-temperate oceans and can travel long distances.
A shark, not a whale
It breathes through gills and has a cartilage skeleton — it's a shark. The name comes from its whale-like size.

What does Endangered mean? The IUCN Red List is the world's main record of how threatened species are. "Endangered" means the whale shark faces a very high risk of extinction in the wild. It is not extinct, and it is not listed as Critically Endangered — but its global population is going down.
Why it matters. Whale sharks grow slowly and take many years to mature, so populations recover slowly once numbers fall. Protecting them today helps keep healthy oceans for the future.
Fishing gear
Accidental capture in nets and other fishing gear.
Vessel strikes
Whale sharks often feed near the surface, where boats can hit them.
Other human pressures
Targeted fishing in some regions and poorly managed tourism add to the strain.

Why Whale Sharks Need Our Protection
Responsible tourism can give local communities a reason to protect whale sharks — but only when encounters are calm, respectful, and well managed.
Healthy oceans support the plankton whale sharks depend on. Reducing pollution and protecting coastal habitats helps them and countless other species.
Scientific research — including photo identification from each shark's unique spots — helps experts understand where whale sharks travel and how populations are changing.
Fewer harmful interactions, such as boat strikes, touching, and crowding, give each animal space to behave naturally.
Our principles
Responsible Whale Shark Encounters
- Never feed or touch whale sharks.
- Keep a respectful distance and follow your guide's instructions.
- Do not chase, block, or harass the animal.
- Respect local regulations and marine wildlife.
- Remember they are wild animals — sightings are never guaranteed.
