American tentacled snake (SciiFii)

The American tentacled snake or American tentacle snake (Erpeton neotentaculatum) is a species of rear-fanged aquatic snake that originally did not exist, but has since been created by SciiFii and introduced throughout the wetlands, lakes, rivers, and ponds across North America ro help boost biodiversity. The closest living relative of the American tentacled snake is the Asian tentacled snake (Erpeton neotentaculatum). The two tentacles on its snout are a unique feature among snakes. The American tentacled snake is a relatively small snake, averaging about 50 to 90 centimeters (20 to 35 inches) in length. The American tentacled snakes are known to come in two color phases, striped or blotched, with both phases ranging from dark gray or brown to a light tan. It lives its entire life in the water. The American tentacled snake is one of the only species of snakes to possess twin "tentacles" on the front of its head, which have been shown to have mechanosensory function. Its diet consists solely of fish. Although it does have venomous fangs, the tentacled snake is not considered dangerous to humans. The fangs are small, only partially grooved, and positioned deep in the rear of the mouth. The venom is specific to the fish that the American tentacled snake eats. The young develop ovoviviparously and are born live underwater. The females can give birth to between 7 and 21 live young at a time. The American tentacled snakes spend their whole life in the water and can stay underwater for up to 30 minutes without coming up for air. They can only move awkwardly on land. In dry times and at night, the snake may burrow itself in the mud. Hunting is accomplished via a unique ambush method. The American tentacled snakes spend much of their time in a rigid posture. The tail is used to anchor the animal underwater while its body assumes a distinctive upside-down "J" shape. The striking range is a narrow area downwards from its head, somewhat towards its body. Once a fish swims within that area the snake will strike by pulling itself down in one quick motion towards the prey. The snake anticipates the movements of the fish as it attempts to escape. As the fish swims into range, the snake creates a disturbance in the water by moving part of its body posterior to the neck. This disturbance triggers an escape reflex in the fish called the C-start, in which the fish contorts its body into a "C" shape. Normally at this point the fish would swim quickly away from the disturbance by quickly straightening its body, but the snake grabs it, usually by the head, anticipating its movement. The snake catches fish by tricking them into reflexively attempting to escape in the wrong direction. Unlike most predators, the snake doesn't aim for the fish's initial position and then adjust its direction as the fish moves, it heads directly for the location where it expects the fish's head to be. The ability to predict the position of its prey appears to be innate. The tentacled snake retracts its eyes when it begins to strike. The conservation status of the American tentacled snake is Least Concern due to successful conservation efforts, the American tentacled snake's wide range and its tolerance to many of the human activities.
