The dragosnapper replaced its ancestor in Yokto Island. Unlike its ancestor, it has gotten larger than its ancestor. However, its legs have shrunken down to a smaller size in order to sneak around in the violetgrass. Even though its legs are short, it can still run very fast. Its tail-spike has also become serrated, which helps it slash its prey. An important adaptation it went through was that its sail can fold down, which conceals it even more. Some other changes include a stronger sense of smell, and laying hard-shelled eggs due to the fact there aren't enough pools of water.
The way it hunts is that it crawls silently in the violetgrass, then when it gets close enough, it bites on the prey and slashes it with the tail-spike. Next it follows the prey's blood that it left behind until it comes across its meal. Finally it tears and shreds apart the corpse and eats it. Sometimes, when a bunch of dragosnappers find a meal at the same time, they engage into feeding frenzies.
To help make sure its prey dies quickly, the dragosnapper has evolved a new weapon, a paralyzing venom. The venom is found in glands inside the spines on its sail. The venom is primarily used for defense, but can be used to hunt. How it hunts with its venom is unusual: it folds its sail, crawls underneath its prey, unfolds its sail quickly, which slashes and injects venom into the underside of its prey. After the prey runs away, the dragosnapper follows and when it finds its food, it immediately attacks and kills the prey. Sometimes, when there isn't much to eat, they'll eat their own kind, whether it is weaker dragosnapper or a dead one.
Some other important evolutions are that it is an excellent swimmer, it can go for several months without food, and the female has developed a third claw on the back of its feet. When mating season arrives, they all swim out of the larger island and mate on the smaller island. Next the males return to the larger island, while the female digs a burrow with its third claw and lays its eggs there.
It guards them very carefully until they hatch. While it guards its eggs, the dragosnapper hardly eats at all except any creatures that might pass by. Next the mothers leave the babies on the smaller island and move out to the larger island. After the baby dragosnappers are grown up, they go into the larger island and the cycle continues.
