Crustaceans; phylum Arthropoda

When we set up this crustaceans section we had expertise in SCUBA diving and PADI courses. BUT we were sadly ignorant of Koh Phangan marine arthropods!
As we learn more about the complexities of crustaceans we are re-structuring the section to try to reflect correct classification. Consequently some of the “breadcrumb” navigation at the top of the page is mildly dysfunctional, but we will have to live with it…

You are unlikely to see these super-small, cryptic creatures unless you dive with a magnifying glass!

The biggest section, including the Anomurans, Brachyurans (true crabs), Carideans (most of the prawns) and Stenopideans. (3 Albums, 1 Gallery)

A morphologically diverse class of generally small crustaceans, also referred to as the non-decapods.

Mantis Shrimps are not true prawns at all - they are not even Decapods. However they do look very much like a long bodied shrimp when they come out of their burrows. (2 Galleries)

These weird beasties are not actually Crustaceans - but they are closely related members of the phylum Arthropoda. Only a few millimetres in size.
