Death from prawn trawls often comes either from drowning or being crushed. It can grow up to a meter in length, and in some cases up to two meters. All sea snakes are ovoviviparous (development of eggs that remain within the mothers body up until they hatch or are about to hatch.). Olive Sea Snakes live to about 15 years and gets its name from the color of its skin. [5], While there are not many threats to the Aipysurus laevis, man-made dangers do exist for it. These snakes can generally grow to be about 1 meters long, but some individuals have been observed with over 2 meters in length. Olive sea snakes is one of the most dangerous sea snakes that roam in the ocean and sea. It has a flattened, paddle-like tail and a large lung that allows it to go hours between breaths at the surface.
[7] Life expectancy of the snake is about fifteen years, sometimes a bit longer. Olive Sea Snakes are naturally curious and are known to approach scuba divers, not aggressively but inquisitively especially at night. Courtship usually involves several males and a few female. A name published by John Edward Gray, Aipysurus jukesii, is regarded as a synonym for this species. Individual females probably breed only every other year. The young are born live in litters of about two to five. The Olive Sea Snake or the golden snake is a species found in the Indo-Pacific. Given its length, it has special light sensing organs in the tail that allow it to remain totally hidden including the tail, in its preferred hiding places among the reef during daylight hours. The shape of the olive sea snake is mostly cylindrical, with a flattened tail shapes as a paddle.
Synopsis of Oceanography & Marine Biology.
This snake in particular has venom that contains enzymes which break down the prey from within for easier digestion. Most likely this helps it conserve energy needed for the production of expensive venom, as eating mollusks or fish eggs would not need spending any venom. The exact toxicity of the snake is not known. [2] The olive sea snake is a marine snake species that is characteristic to the Indo-Pacific region. "Cutaneous photoreception: a new sensory mechanism for reptiles". When not foraging at day or night or surfacing to breathe, Olive Sea Snakes hide under any convenient cover rather than returning repeatedly to the same shelter. The composition of the venom most likely contains both neurotoxins and myotoxins. The larger females produce eggs in the southern spring (October). In some species, the young are quite large, sometimes up to half as long as their mother. Male snakes reach maturity after 3 years while females after 4 to 5 years. Its fangs may be 7 millimeters long and unlike many other sea snakes, it has a wide diet feeding on fish, fish eggs, cuttlefish, prawns, crabs and mollusks. [11], The specific name, pooleorum (masculine, genitive plural), is in honor of Australian fishermen "W. and W. Poole" who collected the holotype. If stranded ashore, they do not survive for long. Females can give birth up to five young at a time.

The former acts by enabling signaling between nerve cells while the latter cause muscle cell destruction and necrosis, paralyzing the prey. The olive sea snake is a marine snake species that is characteristic to the Indo-Pacific region. It belongs to the genus Aipysurus of the Elapidae genus, a group that comprises of many sea snake species as well as terrestrial venomous snakes such as adders and cobras.
Also known as the golden sea snake or olive-brown sea snake, the species is usually mild in temperament albeit venomous, feeding on a diverse diet including fish and mollusks. It has a sturdy body with a flat, paddle-like tail and is purplish-brown above with paler-brown on the underside. It has brownish and purple scales along the top of its body whilst its underside is a white color. The olive sea snake swims using a paddle-like tail. [7], Aipysurus laevis has been found to have photoreceptors in the skin of its tail, allowing it to detect light and presumably ensuring it is completely hidden, including its tail, inside coral holes during the day. * Marbled Sea Snake or Spiny-tailed Sea Snake (Aipysurus eydouxii) This 1 meter long snake occurs throughout Southeast Asia and parts of Australia. Growing to lengths over 6 feet (2 meters), this species is well adapted to a life on coral reefs. [1] It uses venom to incapacitate its prey. It has a sturdy body with a flat, paddle-like tail and is purplish-brown above with paler-brown on the underside.
[8], Males can reach sexual maturity in their third year, while females do not until their fourth or fifth year. photos that may be disturbing to young children! Large bony fishes, sharks and predatory birds are known to eat juvenile and even adults. While other species have not been tested, A. laevis possibly is not unique among sea snakes in this respect. Colors of the scales usually range from olive to brown or even dark yellow. This species prefers to venture off of the reef at night, to hunt for bottom dwelling prey that is also targeted by fishers. The Olive Sea Snake is a highly venomous snake that actively hunts small to medium-sized fishes and benthic invertebrates including prawns and crabs. Olive Sea Snakes are not fished by people, but they are at risk of accidental capture by fishers targeting other species particularly bottom trawlers. Like all reptiles, Olive Sea Snakes breathe air but unlike the sea turtles, crocodiles, sea kraits and other marine reptiles which must nest on shore, the Olive Sea Snake’s entire life cycle occurs in the ocean. Related Species. [6] In rare cases there can be ten or eleven young at once. A special adaptation of this snake is a cell formation in the flattened tail that is apparently responsible for detecting light. The fertilization process takes place inside the female, and after a period of about 9 months, it can give birth to 2 to 5 young, in some rare cases even as many as 11 or 12. [1] It can also be found in the north-western Atlantic Ocean and the north-eastern Pacific Ocean. Usually has some creamy-white scales scattered over body. While it can be aggressive towards prey, attacks on divers or larger animals are usually rare, though if provoked it will engage the attacker. It has brownish and purple scales along the top of its body whilst its underside is a white color. The is quite common in the Indo-Pacific coastal regions.
This is a venomous sea snake species which inhabits coral reefs. Aipysurus laevis is a species of venomous sea snake found in the Indo-Pacific. The young are born alive in the water where they live out their entire life cycle.
As opposed to many other sea snakes, the olive sea snake doesn’t have a specialized diet. The young are born alive in the water where they live out their entire life cycle. Olive Sea Snakes do not leave the water to nest or for any reason at all. They can be aggressive but attacks on divers are rare. This snake has brownish and purple scales along the top of its body with white underside.
It is found mainly in warm coastal waters in the Indo-Pacific where they live on coral reefs, lagoons & rocky shores to depths of 5 to 45 meters. These fish are.

Marine Biology, Oceanography & Ocean Engineering, The Future a.k.a. The snake uses these sensors to detect light in order to hide itself better and become invisible to many predators that feed on it, mainly sharks and ospreys. Also, it is a common and widespread species that lives on coral reefs or hide in small coves and protective coral areas. Though scientists generally believe some populations of Olive Sea Snakes to be decreasing, it is considered a species of least concern across its entire distribution. Olive snakes sometimes are washed up onto the beach by a storm or strong current. Prawn trawls are one of the greatest threats for the creature, up to 50% of olive sea snakes caught in trawls are killed, while the ones that survive usually suffer injuries.
It prefers to hide inside coral reefs.
