FAQ
Frequently Asked Questions

Yes, primarily. Its most common use is as an adjective (e.g., brachyuran anatomy). It can also be a noun referring to any member of the group.
In crustacean taxonomy, the classic opposite is a 'macruran' (long-tailed), such as a lobster, crayfish, or shrimp. Another contrasting group is 'anomuran' (e.g., hermit crabs, king crabs).
