Ligia dilatata

Identification

It has a finely granular surface and a body that is slightly convex, as well as eye that are large and convex. It has relatively small uropods.

It can be differentiated from L. glabrata, with which it shares some range, by its antennae. The antennae of L. diletata are longer, reaching the end of its thorax.

Habits

L. diletata feeds extensively on dislodged Ecklonia maxima and Laminaria pallida that wash up on shore. They gather in large numbers on these kelp.

The species lives about 2 years. Females start reproducing at 12 months but, unlike males, probably do not survive to breed twice. The brood period is 5 to 6 weeks.

Growth is slow during summer but faster in winter when food is more plentiful.
