Ligia exotica, also called sea roach or wharf roach, is a woodlouse-like isopod, a sea slater in the family Ligiidae. It is found in various parts of the world living on rocky coasts and harbour walls just above high water mark. Ligia exotica - WikiMili, The Free Encyclopedia - WikiMili, The Free En.
The isopod Ligia oceanica may seek refuge in crevices in the rock, and due to the decreased effect of desiccation in these damp caves, other species such as the anemone Actinia equina and spirorbid polychaetes are able to extend further up the shore than normally found on open rock.
Upper to lower shore sand- or pebble-scoured cave walls characterised by an impoverished faunal assemblage which may include bryozoan crusts, scattered sponges Halichondria panicea, barnacles such as Semibalanus balanoides or often large Balanus crenatus and the limpet Patella vulgata.The isopod Ligia oceanica may seek refuge in crevices in the rock, and due to the decreased effect of.

Evolutionary ancient species are amphibious, such as the marine-intertidal sea slater (Ligia oceanica), which belongs to family Ligiidae. Other examples include some Haloniscus species from Australia (family Scyphacidae), and in the northern hemisphere several species of Trichoniscidae and Thailandoniscus annae (family Styloniscidae).
In Ligia oceanica the clypeolabral musculature is developed asymmetrically, which is seen in connection with the asymmetry of the mandibles. Moreover, the adductor of the labrum tip does not originate at the frontal plate as in all other isopods that have been investigated in this respect, but takes ist origin at the proximal fold of the clypeus.
