Description |
Venomous |
| Venom yield is low, but still considered potentially dangerous to humans. |
| Size |
| 10 - 45 inches in length (25 - 114 cm.) Most snakes seen in the eastern Pacific are 18 - 25 inches long (46 - 64 cm.) |
| Appearance |
| A marine serpent with a narrow elongated flattened triangular head with nostrils set high on the top. The body is flattened and the tail even more so to facilitate swimming. Dark brown or black with a bright yellow or pale yellow underside which extends up the sides. Sometimes the underside is darker, sometimes a snake is all yellow or yellow with a narrow black stripe on the back. The tail is marked with black spots or bars. There are small fangs on the front of the upper jaw. |
| Behavior |
| Diurnal and primarily aquatic. Undulates the flattened tail and body side to side to swim and dive. Unable to move when washed on shore. An alert snake, may dive when approached. Not known to be very agressive, usually reluctant to strike, and often strikes without injecting venom. |
| Diet |
| Eats small surface-dwelling fish and eels. |
| Reproduction |
| Live-bearing. Probably breeds only in areas of water as warm as 68 degrees F (20 C) or warmer. Large congregations of snakes have been found which were thought to be breeding congregations. Young are born in the ocean, or mangrove swamps or rocky tidal areas near shore. |
| Range |
| Uncommon in California; recorded from San Clemente beach in Orange County and from San Diego County. Probably the most widely distributed snake in the world, inhabiting the Indian and Pacific Oceans, including the coasts of Africa, Asia, Australia, Mexico, including Baja California, and Central America. |
| Habitat |
| Warm ocean waters. Usually seen within a few miles of the shore, but also occurs far out to sea. More common along slicks where ocean currents converge creating quite waters with surface debris which attract the fish this snake preys upon. |
| Conservation Issues (Conservation Status) |
| None. |
