shore crabs

These 2 fine specimens are adults, not that often found as they tend to move lower down the shore the older they get. The species is extremely variable in its juvenile stages but most adults look like these. The triangular "tail" between these crabs' legs show that they are both males - on females this structure is broader to accommodate the eggs.

Shore crab

The triangular 'tail' on a male usually has five segments and the female has seven. The extra segmentation allows more flexability for holding the eggs. When a female is holding eggs she is known as being in berry.
