Mantagrems are an aquatic species that live primarily in lakes and oceans. These hybrids can grow up to amazing lengths, the longest recorded one being up to 11 feet long. They have traits akin to the mantashark species, sporting a thick hairless hide meant for gliding through water, a shark-like tail, and mantaray’s fins with characteristic eyes shown on each wing.
Each mantagrem has two forms, an aquatic form and land form. Below the water, they have their wings fully out to glide to amazingly deep depths to catch prey. On land, they are able to make their wings and tail shrink to small sizes (or disappear!) in order to reduce weight on their bodies. Despite being able to be on land, they cannot stay there without having their bodies hydrated.
