I was wondering if someone could shed some light on this for me. Define crustaceans and why isopods are considered one

 

[_bob_]

Isopods are one of the most diverse orders of crustaceans, with many species living in all environments, but are most common in shallow marine waters.

thanks i should have done that. more of what i meant though was what are the specific characteristics the make a crustacean a crustacean and not a insect, arachnid, ect. and how do isopods relate to that. but wikipedia would work for that aswell i guess

Well i dont know to much but i know that some have gills [i think all of them do but hey im no expert ]

In that case see :
http://en.wikipedia.org/wiki/Arthropod#Classification_of_arthropods

First thing that comes in mind for me is number of legs.
Insect = 6 legs.

Another interesting fact about terrestrial isopods..... When they die they will start to smell like seafood if kept in a moist environment and left to decay for a day or two.
