This topic is about the Arthropod Class Crustacea-Malacostraca

Crustaceans are classified as one of those inconvenient intermediate taxonomic levels, the subphylum. The varieties of interest to trout anglers are in the class Malacostraca.

It contains the orders of scuds (Amphipoda), sowbugs (Isopoda), opossum or mysis shrimp (Mysida), and crayish (Decapoda). Crayfish and scuds are both extremely important trout prey.

Posts: 2737		Yeah, I mention that on this page.

I decided not to include all the sub-this and infra-that taxonomic levels on this site and stick to the ones covered in high school biology, because it makes the navigation much easier and it's sufficient for anglers' purposes.

For the rare cases in which some well-known taxon falls on a more obscure level (like crustaceans, damselflies, and dragonflies), I've appended or prepended it to the listed taxon with a hyphen and explained the details in the corresponding description. It's not the most graceful system but it works.
