Anostraca

/ænəˈstrækə/ noun

Definition

A class of small crustaceans that lack a carapace, including brine shrimp and fairy shrimp.

Etymology

From Greek 'an-' (without) + 'ostrakon' (shell/carapace). The taxonomic class name literally means 'without a shell,' referring to their lack of the hard carapace found in other crustaceans.

Kelly Says

Brine shrimp (Anostraca) are used in space experiments because their eggs can survive extreme conditions and hatch instantly in saltwater—they're basically evolution's way of creating a living freeze-dried food packet.
