Written also zoæa. ✍ 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.
