Concernant le Crabe bleu américain, Callinectes sapidus, qui a été le plus étudié, la question
n’est pas encore résolue. Des recherches diverses ont conduit leurs auteurs à des avis parfois
divergents.
« In the Chesapeake Bay, sexual maturity is reached after 18 to 20 postlarval molts,
at the age of 1 to 1½ years. Males continue to molt and grow after they reach sexual
maturity. It is generally accepted that females cease to molt and grow (terminal
molt) when they mature and mate. However, new research suggests that mature
females (sooks) will continue to molt given the right set of circumstances. Jeffery
Shields of the Virginia Institute of Marine Science says that it was once believed that
blue crabs experienced a terminal molt which was considered the second molt after
puberty for males and the only molt after puberty for females. While this is generally
the
case,
most
portunid
crabs
do
continue
to
molt.»

Les mâles continueraient de muer après leur mue de puberté contrairement aux femelles qui
généralement feraient une mue terminale. Dans certains cas particuliers, elles pourraient
muer.
« Data from the present study indicates that the y-organ remains functional in
mature female blue crabs, C. sapidus. further supporting a diapause stage rather
than terminal anecdysis. » (Havens & Mcconaugha, 1990)
