Paracerceis sculpta is a species of marine
Pacific from Southern California to Mexico, but has since been introduced to many other countries.[3] Adults are herbivorous and consume algae but juveniles are carnivorous and consume moulting females.[2] They reproduce in sponges but do not feed near them.[4]
Reproduction
Their
Uta stansburiana).[5]
The α males guard a
immotile. The length of gestation depends on the temperature of the water – the cooler the water, the longer it takes. The female provides nutrition directly, her internal organs and muscles degrading throughout the gestation. This gives the juveniles a headstart, before they begin feeding on intertidal algae. The females die shortly after juveniles are released.[6]
Introductions
Paracerceis sculpta is thought to have been spread around the world by
Mediterranean[3] and Japan.[1] The wide range of water temperatures in its native range is thought to contribute to its ability to be spread by shipping.[3]
