The fishing grasper split from its ancestor the greeper. Unlike its slim ancestor it has become bigger and bulkier in order to survive the cold environments better. Also in order to survive the cold its black colorations are found at random patterns mainly on its back and upper side in order to absorb heat.
Though they have a varied diet they mostly feed by fishing fauna from the water. Using their grasping claws that use both their fingers and sharp nails they walk into shallow waters or swim towards tiny islands near shore and there they fish their prey. With lots of inner-species competition for food some fishing graspers migrate in the light summer months to the south tundra to feed and return in the winter. In the south tundra their main food source is the corkscrew uksips and they have even learned to make holes in thin ice using their claws and fish through the ice. They can store massive amounts of fat in their back-bump for the hard winter months. They are generally aggressive in nature they usually live in families raising their young together and sharing their meals.
