Ligia Simoni
''Ligia'' is a genus of isopods, commonly known as rock lice or sea slaters. Most ''Ligia'' species live in tidal zone cliffs and rocky beaches, but there are several fully terrestrial species which occur in high-humidity environments. Ecology Coastal ''Ligia'' species exhibit a mixture of terrestrial and marine characteristics, drying out easily, needing moist air and proximity to water to retain water. While they have gills and can exchange gas under water, they only do so when escaping terrestrial predators or being dislodged by wave action. They do not move swiftly in the water and are open to marine predation. They are well adapted to rocky surfaces and avoid sand, which opens them to terrestrial predation and desiccation. Taxonomy It has been suggested that ''Ligia'' is more closely to marine isopods than it is to true woodlice. Species Species separation is at times difficult because of sexual dimorphism. For example, males usually have longer and wider antennae t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligia Oceanica
''Ligia oceanica'', the sea slater, common sea slater, or sea roach, is a littoral zone woodlouse, living on rocky seashores of the European North Sea and Atlantic coastlines. ''L. oceanica'' is oval, twice as long as broad, and may reach up to in length, making it one of the largest Oniscidae, oniscid isopods. Its colour may vary from grey to olive (color), olive green, and it has large compound eyes and long antenna (biology), antennae, two-thirds as long as its body. ''L. oceanica'' is found in temperate, temperate waters from Norway to the Mediterranean Sea, and from Cape Cod north to Maine. It is a common species, occurring wherever the substrate of the littoral zone is rocky, and is especially common in crevices and rock pools and under stones. It is a nocturnal animal, nocturnal omnivore, eating many kinds of seaweed, diatoms, and detritus, with a particular fondness for bladder wrack (''Fucus vesiculosus''). ''L. oceanica'' individuals live for 2–3 years and usual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligia Baudiniana
''Ligia baudiniana'' is a woodlouse in the family Ligiidae. It has a coarsely granular surface and large eyes that are very close together. Distribution ''L. baudiniana'' has been found from Bermuda to the Yucatán Peninsula and south to Panama Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Co .... Behavior They venture out in great numbers in the intertidal zone at low tide, then they retreat as the water returns, but they need the water to keep their gills warm and have never found more than from shore. They cannot live in seawater for extended periods, as can '' L. oceanica'', for example. They survive best in moist environments, but cannot survive in fresh water, most likely due losing their vital salts via dilution. To hydrate, they turn away from the water and dip thei ...

Ligia Exotica
''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. Description ''Ligia exotica'' can grow to in length, with the males being rather bigger than the females. The general colour is dark grey, sometimes with brown flecks, and the appendages are pale brown. The head has a pair of long antennae which exceed the length of the body, and two unstalked, bulging eyes. The body is flattened dorsally and has seven thoracic segments, each with a pair of legs, and six abdominal segments. The first five of these bear flat, membranous gills and the sixth bears a pair of long, forked uropods.''Ligia exotica'': Wharf roach Smithsonian Marine Station. Re ...

Ligia Dilatata
''Ligia dilatata'' is a woodlouse in the Family (biology), family Ligiidae. Identification It has a finely granular surface and a body that is slightly convex, as well as eyes that are large and convex. It has relatively small uropods. It can be differentiated from ''Ligia glabrata, L. glabrata'', with which it shares some range, by its antennae. The antennae of ''L. dilatata'' are longer, reaching the end of its thorax. Habits ''Ligia dilatata'' 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. References External links * {{Taxonbar, from=Q2334316 Woodlice Crustaceans described in 1833 ...
