Why Pufferfish Around Koh Tao Are So Unique

Pufferfish belong to the Tetraodontidae family and are found in tropical and subtropical waters around the world. While they might look cute and harmless, these fish have some of the most unique adaptations in the marine world. If you’re spotting pufferfish around Koh Tao, you’ll notice these traits up close on many of our local reefs. If you’re wondering where to see pufferfish, Koh Tao offers plenty of great options across its dive sites. Here’s why they stand out.

1. The Iconic Puffer Move

When threatened, pufferfish can rapidly inflate their bodies by swallowing water or air, making them appear much larger than they actually are. This is a clever defence mechanism that deters predators who suddenly find their prey twice the size. Divers rarely see this behaviour, and for good reason, as it is very stressful for the fish. On many Koh Tao dive sites with pufferfish, you’re far more likely to see them calmly hovering around the reef than displaying this defence.

2. Toxic But Adorable

Many species contain tetrodotoxin, a powerful neurotoxin that makes them extremely dangerous to predators (and even humans if consumed improperly). For divers exploring Koh Tao marine life, pufferfish encounters include their expressive faces and clumsy swimming style.

3. Goofy Personalities

Pufferfish are known for their curious and sometimes playful behavior. Unlike many fish that dart away at the first sign of a diver, pufferfish often float calmly, watching you with their large, round eyes as if they’re sizing you up, a common and memorable sight when diving around Koh Tao.
