Shore clingfish
The shore clingfish, ''Lepadogaster lepadogaster'', is a clingfish of the family Gobiesocidae, found in the eastern Atlantic from Ireland and Britain, where it is more commonly known as the Cornish lumpsucker, and in the Mediterranean, between latitudes 46° N and 30° N. ''L. lepadogaster'' often inhabits underwater boulder fields consisting of smooth rocks and large pebbles. 〔Hofrichter, R. and Patzner, R. A. (2000), Habitat and Microhabitat of Mediterranean Clingfishes (Teleostei: Gobiesociformes: Gobiesocidae). Marine Ecology, 21: 41–53. doi: 10.1046/j.1439-0485.2000.00689.x〕 Its length is up to 65 mm. ''L. lepadogaster'' is also classified as a cryptobenthic fish. Cryptobenthic simply means that the fish is both behaviorally and visually cryptic.〔Depczynski, M., & Bellwood, D. R. (2003). The role of cryptobenthic reef fishes in coral reef trophodynamics. Marine Ecology Progress Series, 256, 183-191.〕 The term is also used mainly to describe adult fish of a certain size, roughly around 5cm in length.〔http://www.fishbase.org/summary/Lepadogaster-lepadogaster.html〕
The clingfish gets its name from the ability of the fish to attach itself to the rock walls of the ocean shore. It does this by having pelvic fins that have been adapted to form suckers. These suckers keep the clingfish strongly attached to the rocky surfaces off the shorelines. In addition to these suckers, the front fins of the clingfish are much stronger to aid in clinging to the rocks. The clingfish has other adaptations that allow it to inhabit rocky surfaces and reduce predation. For instance, the clingfish has a triangular shaped head and a flattened body. These characteristics allow the clingfish to reduce the drag of the water from the waves pushing and pulling against it.〔http://www.marlin.ac.uk/species/Lepadogasterlepadogaster.htm Marlin site〕 ''L. lepadogaster'' also has distinct differences from the other species of Lepadogaster. For one, ''L. lepadogaster'' has a much more active lifestyle than the species "L. purpurea''. This is evident in both ''L. lepadogaster's'' swimming speed and in its more frequent feeding periods〔Gonçalves, D. M., Gonçalves, E. J., Almada, V. C. and Almeida, S. P. (1998), Comparative behaviour of two species of Lepadogaster (Pisces: Gobiesocidae) living at different depths. Journal of Fish Biology, 53: 447–450. doi: 10.1111/j.1095-8649.1998.tb00992.x〕
The cornish lumpsucker survives by consisting on a diet of mostly detritus material, meaning that it lives off the dead organic matter of its environment.
