Yellow Sea Serpent

Description:

See snake scales for terminology used here The body of this snake is compressed, posteriorly less than half the diameter of the neck; the body scales are juxtaposed, subquadrangular in shape, and in 23–47 rows around thickest part of body; ventral scales, 264–406 in number, are very small and, if distinct, divided by a longitudinal groove, but usually are indistinguishable from adjacent body scales. The head is narrow, with an elongated snout; head shields are entire, nostrils are superior, and nasal shields are in contact with one another; the prefrontal scale is in contact with second upper labial; one or two preoculars, two or three postoculars, and two or three small anterior temporals are present; seven or eight upper labials are found, with four or five below the eye, but separated from the border by a subocular. Colors of the snake are variable, but most often distinctly bicolored, black above, yellow or brown below, with the dorsal and ventral colors sharply demarcated from one another; ventrally, there may be a series of black spots or bars on the yellow or brown background, or the yellow may extend dorsally so there is only a narrow middorsal black stripe, or a series of black crossbars (M.A. Smith, 1943: 476–477, gives more complete descriptions of the color pattern variants). Total length for males is up to 720 millimetres (28 in), for females up to 880 millimetres (35 in); tail length for males is up to 80 millimetres (3.1 in), females up to 90 millimetres (3.5 in).

Habitat:

These snakes breed in warm waters; they are ovoviviparous with a gestation period of about six months. According to Ditmars, females bear live young in tidal pools.[5] They are helpless on land, and they sometimes form large aggregations of thousands in surface waters. These snakes use their neurotoxic venom against their fish prey. No human fatalities from envenomation are known.
