A male. Note the small pleopods and lack of a claw on the 5th walking leg.
Crustacea Panulirus interruptus MALE abdomen
Males transfer gummy sperm packets to the underside of females. When the females ovulate, they manually fertilize them using the packet they carry around with them. It's a big ocean floor out there and one might imagine the odds of finding a male at the time of ovulation.
Panulirus female sperm packet
A female. Notice the large pleopods (used to brood her thousands of bright orange eggs), and the small claws present at the tip of each 5th walking leg.
Crustacea Panulirus interruptus FEMALE abdomen
A gravid female with bright orange eggs (see lower hand and finger) and a sperm packet (upper hand and finger).
Crustacea Panulirus interruptus GRAVID
The planktonic phyllosoma larva of a California Spiny Lobster.
