ZOEA
Zo"ë*a, n. Etym: [NL., fr. Gr. (Zoöl.)
Definition: A peculiar larval stage of certain decapod Crustacea,
especially of crabs and certain Anomura. [Written also zoæa.]
Note: In this stage the anterior part of the body is relatively
large, and usually bears three or four long spines. The years are
conspicuous, and the antennæ and jaws are long, fringed organs used
in swimming. The thoracic legs are undeveloped or rudimentary, the
abdomen long, slender, and often without appendages. The zoëa, after
casting its shell, changes to a megalops.
