What does zoeae mean?
Zoeae are the larval form of certain decapod crustaceans, including crabs, shrimp, and lobsters. The plural is zoeae, while one such larva is called a zoea. Most zoeae are small, free-swimming organisms that differ considerably in appearance from the adults their species will become. They disperse through the water, feed on microscopic material, and later undergo substantial developmental changes as they approach the juvenile or postlarval stage. The term is principally used in marine zoology, aquaculture, fisheries research, and the study of crustacean development. Although familiar to specialists, it is uncommon in general prose and should be used in contexts where the technical distinction between a zoea and a later crustacean larval stage matters.

Etymology of zoeae
Zoological Latin zoea derives from Ancient Greek zōē, meaning “life.” The name reflects the zoea's status as a living, active larval form of the crustacean. Related English words such as zoology, zoologist, and zoetrope were ultimately developed through the same Greek life-root in combinations meaning animal life, the study of animals, and turning animal figures respectively.
