N. Crescenti et al., DEVELOPMENTAL STAGES OF ANTARCTOMYSIS-OHLINII HANSEN, 1908 (MYSIDACEA) IN TERRA-NOVA BAY, ROSS SEA, ANTARCTICA, Journal of crustacean biology, 14(2), 1994, pp. 383-395
Detailed descriptions of 2 intramarsupial stages, the juvenile stages,
and male and female immature stages are given. Stage II shows an abun
dant yolk mass, 2 Pairs of rudimentary antennae, and Poorly developed
mandibles. In stage III the yolk is absorbed and all the thoracic and
abdominal appendages project freely. The juvenile stage starts when th
e larva leaves the marsupium. The antennulae, the antennae, and the ma
ndibles assume the typical aspect of those of the adults. A statolith
inside the statocyst appears in the endopod of the uropods. A morpholo
gical peculiarity of its immature stages (both in males and females) i
s described and referred to as sexual dimorphism.
