You usually see the antenna before the shrimp - wispy filaments peeking out of a crack. Banded coral shrimp are generally found in pairs, often with a moray eel close by.
Sharks are known for their impressive teeth... but in the fish world it's the moray eels with their gaping jaws of inward-slanted fangs that you should be wary of.
Everyone wants to know if you see sharks when scuba diving. If you're very lucky you may get close enough to see the texture of their skin!
Introducing Idiotropiscis aotearoa
In February I found a pair of pygmy pipehorses near the Bay of Islands in northern New Zealand. It was a new species and now it has a name: Idiotropiscis aotearoa.
Small and shy - the life of a triplefin
I'm fascinated by the tiny triplefins that make up a big part of the New Zealand reef ecosystem. We have 26 endemic species - triplefins that are only found naturally occurring in NZ.
Octopuses can do this cool thing - change colour and texture. They can blend into their surroundings and become practically invisible. Thousands of colour-changing cells called chromatophores are manipulated to pull off this remarkable feat.
Named for its polka dots, the Clown nudibranch (Ceratosoma amoenum) livens up New Zealand's underwater world.
Someone is always watching
Scorpionfish (Scorpaena cardinalis) behave like rocks so they can ambush their prey. Sometimes they ambush divers.
This striking triplefin is found all around New Zealand, from the Three Kings Islands in the north to the Auckland Islands in the south.
