The tanaids are distributed worldwide and are abundant in marine and brackish waters. In addition, they may be involved from the muddy substrate to stems and roots of aquatic macrophytes. Tanaidae family has 19 genera and 72 species.
Thank you Nataly! I love seeing new brief descriptions for higher-level taxa, and I'm looking forward to more of your contributions. I'll also work to get Portuguese set up as a language for the EOL interface - right now we only have about 40% of the interface translated, so it needs some work (see this page for details).
