Contest that is now over, waiting on judging... Just felt like throwin him up! The other entry is next.

Notes in case my hand writing is illegible:
He has a toxin that comes from a venom gland behind the jaw, and goes through the hollow fangs in the front of his jaw that are protected by boney protrusions (the protrusions also help anchor the fangs for a bite so they don't break). The toxin is both a hemotoxin (attacks the proteins in red blood cells) and a neurotoxin (attacks the nervous system). The first one causes internal hemorrhaging when it gets bad and the second causes paralysis on different levels and sometimes seizures or spasms. In combination the toxins are deadly to vital organs such as the kidneys and liver and can also attack the heart, causing irregularities in heartbeat, such as arrhythmias, and in sever cases can cause the heart to give out. It can be treated with a combination of anti venoms from snakes such as the puff adder, gaboon viper, and monocled cobra. A mix of 1:2:2 is preferable, in the order of the snakes listed.

His jaw is also built similarly to a snake, with a special bone called the quadrate bone hinging the top and bottom jaws together, allowing it to swing widely and open a full 180 degrees. The underside of the top jaw contains an organ called the Jacobson's organ, which the long forked tongue drags over when drawing into the mouth, bringing scent particles against it since he has no nose. It is very sensitive. His hearing is mediocre though and his ears are aimed backwards to prevent things from sneaking up on him. His jaw is also split down the middle on the bottom to allow for wide expansion (that throat of his is baggy to allow for stretching). It can expand up to 3x the normal size to swallow prey that is very large whole. His torso is also long to accommodate such prey and his ribs can rotate to stretch.

His claws are long and pointed and allow for good grip on most surfaces, which allow him to go from dead still to around 35mph quite quickly, and his tail is long with a balance at the end to allow for very sharp turns of close to 95 degrees.

His method of killing is to stalk the prey, and dash at them quickly, then bite them and make a hasty retreat. Then he allows his venom to go to work. His skull, teeth, and eyes, are all brightly colored to surprise the prey as he dashes up to them, as they flash brightly in most lights.

His eyes are unique too. They have no pupil and he cannot make out many details of things because of this. Instead, they absorb light from every angle and allow him to detect movement. The light color makes them sensitive to light and he prefers to be out at night, where he has excellent night vision. Unless you are perfectly still, he wouldn't notice you unless he smelled you. The eyes also have no lid. Instead, similar to a snake, they have a single large scale that caps them and protects them from harm and debris. This also makes it hard to sneak up on him when at rest because he still detects movement and it can wake him up.

His height is about 5ft at the shoulder and his weight is around 200 lbs
