The various stages may be isolated in separate fingerbowls. Late nauplii, however, will live for some time in fingerbowls of sea water. The stain, however, is transient. The eggs are distorted while they are still in the ovary, but become spherical in shape after they are placed in sea water. The egg has a rounded point at the vegetal pole and is blunt at the animal pole.
Cleavage is total, unequal, and regular.
