The longneck is a type of sea serpent and lake monster appearing in most sea serpent classification systems. The longneck is the most commonly-reported sea serpent, and, alongside the humped sea serpent, one of the best-known, although it is not known to have been reported prior to the 19th Century.[1]

A. C. Oudemans, classifying the longneck (Megophias megophias) as a giant long-necked pinniped, regarded it as the only significant type of sea serpent.[2] However, later systems have rejected Oudemans' attempts to shoehorn other reports into the longneck file. The long-necked sea serpent (Megalotaria longicollis; French: long cou) was by far the most common type of sea serpent in the Heuvelmans system, the first attempt at comprehensively classifying sea serpents.[3] Although Heuvelmans believed them to be distinct for several reasons, his merhorse has frequently been lumped together with the longneck, and the Coleman-Huyghe system subsumes both into the waterhorse, as subcategories.[4] The Champagne system also includes two longnecks, one cosmopolitan, the other endemic to the North Sea.[5]

Historically, the most widely-supported explanation for longnecks was a surviving plesiosaur or plesiosaur relative,[3] a theory which is still the best-known.[6] However, since the late 19th Century, several cryptozoologists have preferred a speculative, giant long-necked pinniped.[2][3][4] Since the 1890s, several cryptozoologists have argued that the oceanic longneck is identical, or very closely related, to the freshwater long-necked lake monsters reported from temperate latitudes, such as Nessie, Champ, the bunyip, grootslang, and iemisch.[1][7][4] Although beached specimens of longnecks are sometimes reported, these pseudoplesiosaurian globsters are generally identified as decayed basking sharks (Cetorhinus maximus).[6]
