ManoKits or, Mano meaning shark in Hawaiian, and Kit as kitsune, are a species that was discovered on the Hawaiian Islands.

ManoKits usually stand tall between 4' to 5' and weigh up to half a ton due to their big bones. Although these have shark like qualities, this does not mean they can swim because of their weight and also they cannot breathe underwater since they have no gills. Their respiratory system is very close to a human's. As for their eyes, they're 70% of the time closed, or squinted. This is because their pupils cannot contract much at all, so their best vision is when the sun starts to set and later on into the night. This being said, they are very dependent on their hearing. Their tongues are very long and have poisonous spikes/teeth to better take in their food/prey and stun them. Their diet mostly consists of any sea life, and sometimes native fruits/plants found on the island. Their fur also shields them from harsh sun rays and acts like an air conditioner. But when born, the "MinoKits" must be wrapped in a sea kelp as soon as they're born and stay in their cocoon for up to three days so that their skin/fur can fully develop. When newly born for the first three days, the kelp is also a temporary womb, the parents must transfer them over as soon as possible or it could mean death for the little guy. They vocalize with low soft purrs and occasional chirps somewhat like a parakeet. A group can be either called a Pod, or Ohana!
