zoea

[zō′ē·ə]
(invertebrate zoology)
An early larval stage of decapod crustaceans distinguished by a relatively large cephalothorax, conspicuous eyes, and large, fringed antennae.

Zoea

 

a pelagic larva, one of the developmental stages of decapods. The body consists of a cephalothorax and a segmented abdomen. Only the front thoracic appendages (maxillipeds) and only the hind abdominal appendages (uropods; absent in crab zoea) are developed; the rest are in the embryonic state. The eyes are sessile. The zoea swims with the aid of its maxillipeds. The unique crab zoea have an almost spherical cephalothorax (with long fore, dorsal, and two lateral spines) and narrow abdomen.

At the beginning of the benthic stage, the juvenile octopuses were fed a mix of king crab zoeae and live wild juveniles of the crab Petrolisthes laevigatas; later they were fed only juvenile crabs weighing between 0.

Females spawn on the continental shelf at about 30 m of depth, where larvae develop, passing through several changes in feeding habitats, behavior, and physical stages (nauplii, zoeae, myses) (Dobkin, 1961; Ewald, 1965; Jones et al.
If larger eggs produced early in the spawning season yield zoeae and postsettlement juveniles with better survivorship, then the number of postsettlement juveniles should have been high in 1993, and possibly 1994, compared with 1995, assuming that overall spawning effort was statistically similar over months and years.
Zoeae I are completely lecithotrophic, but all yolk reserves are used or disappear after the molt to Zoea II which, as in later stages, is completely planktotrophic (Bauer & Delahoussaye, 2008 and references therein).
