Crabs of Henderson Bay

Crabs live in the intertidal zone and subtidal zones around the world, spending alot of their time hiding under rocks or under ledges. If you do turn rocks over to find crabs and other interestig critters, when you have finished looking, turn the rock back slowly as you may accidently kill those who live underneath it.

Below are some of the common crabs that are found in the intertidal zone, although the Red Rock Crab (Guinusia chabrus) usually lives in the sub tidal zone.

Hermit crabs are crabs that use an old gastropod – snail shell – as their home because they do not have the hard bodies of the other crabs. As they grow to big for their shell, they find a larger one and swap homes. The easy way to spot these is to look for shells that move fast.

The most common hermit crab found here is the New Zealand Hermit Crab Pagurus novizealandiae

Here are some examples of hermit crabs showing the different shells that they live in.
