The shrimp eel (''Ophichthus gomesii'') is an eel in the family Ophichthidae (worm/snake eels).〔Luna, Susan M. “Ophichthus gomesi.” Fishbase.org.http://www.fishbase.org/summary/Ophichthus-gomesii.html〕 It was described by Francis de Laporte de Castelnau in 1855. It is a common inshore species of eel usually found in the shallow Gulf of Mexico and the high-salinity bays where it inhabits muddy habitats. 〔Hoese, H. Dickson, Moore, Richard H. “Fishes of the Gulf of Mexico: 2nd Edition.” Texas A&M University Press. College Station. 2011. p. 151〕 ==Characteristics== The shrimp eel has an elongate body and snake-like shape characteristic of the eels. Individuals are colored brown to gray on their dorsal side with lighter coloration below. Their branchial region (ventral side beind the head) is swollen with a basket-like structure of over-lapping free rays (jugostegalia) underneath the skin but they are often visible through the skin. The tail is fleshy with no caudal or pelvic fins. The common length of an adult is 50 centimeters. The maximum length collected is 91.4 centimeters. Shrimp eels can be distinguished from other eels by their lack of a caudal fin and external jugostegalia (basket-like structure of over-lapping free rays). It can also be distinguished from other snake eels by its lack of markings, well-developed pectoral fin, and dorsal fin originating behind the gill slit.〔Shrimp Eel: Ophichthus gomesi.” Texas A&M University Galveston. http://txmarspecies.tamug.edu. 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shrimp eel」の詳細全文を読む スポンサード リンク
