Female sea spider on hydroid Aglaophenia latirostris, 8 mm across. Moves very deliberately. Feeds on the hydroid. This individual has lost one leg, but it will not be replaced as these arthropods do not molt.
This male sea spider is brooding fertilized eggs he gathered from his mate. The resulting larvae will parasitize the hydroid Aglaophenia on which the adults feed. 8 mm across. These cryptic sea spiders move very slowly.
