Curiously, Emydocephalus is the only sea snake that does not possess palatal teeth. [5] Contrary to the foraging habits of other snakes, the turtle-head tends to eat smaller, more frequent meals rather than larger, infrequent prey: this sea snake feeds solely on fish eggs; specifically, the eggs of demersal fish that attach to the substrate, such as those of damselfish, blennies, and gobies.
In sea snakes, the posterior sublingual glands, located under and around the tongue sheath, allow them to expel salt with their tongue action. [5] [9] Scalation among sea snakes is highly variable. As opposed to terrestrial snake species that have imbricate scales to protect against abrasion, the scales of most pelagic sea snakes do not overlap.
Aipysurus eydouxii, commonly known as the beaded sea snake, [3] the marbled seasnake, and the spine-tailed seasnake, is a species of venomous snake in the family Elapidae. A. eydouxii is unusual amongst sea snakes in that it feeds almost exclusively on fish eggs. As part of this unusual diet, this species has lost its fangs, and the venom ...
• Sea snake (bottom right) Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Only about 100 of the 12,000 extant reptile species and subspecies are classed as marine reptiles, including marine iguanas, sea snakes, sea turtles and saltwater crocodiles. [1]
Elapidae (/ ə ˈ l æ p ə d iː /, commonly known as elapids / ˈ ɛ l ə p ə d z /, from Ancient Greek: ἔλαψ élaps, variant of ἔλλοψ éllops "sea-fish") [6] is a family of snakes characterized by their permanently erect fangs at the front of the mouth.
Unlike fully aquatic ovoviviparous sea snakes, sea kraits are oviparous and must come to land to digest prey and lay eggs. [2] They also have independent evolutionary origins into aquatic habitats, with sea kraits diverging earlier from other Australasian elapids.
Males can reach sexual maturity in their third year, while females do not until their fourth or fifth year. [11] Courtship usually involves a group of males vying for one female, which occurs in open water. At times, divers are approached by male sea snakes, possibly due to male sea snakes mistaking divers for female sea snakes. [16]
When startled, frightened, or threatened, M. euryxanthus will hide its head under its body and raise and tightly curl its tail. While in this posture, it will "fart": snakes do not have an anal cavity in the sense that humans and most mammals do, but rather a tract that allows for both disposal of waste and for laying of eggs in females.
