Hullback

The hullback split from its ancestor, the seashellsnapper. However with so much competition in Bumpy Polar Coast, its ancestor was forced out and eventually went extinct there. Now in the open ocean, it had to drastically adapt or die. One major adaption is that it now floats on its back. Both males and females have these new hull-like backs that are hollow and keep them afloat on the water surface. One of their spikes now acts as a keel for their shell and a 2nd spikes acts as the front bow. Males and females are now the same size and have no sexual dimorphism. Their back feet are now webbed, however they are not used for swimming but are used as "foot-sails". They can open and close them or adjust them for the winds. Normally they sit with their feet closed and drift with the current. However if there is a wind they can use it to move faster across the sea. The webbing is bioluminescent which means they can be used to communicate or try to attract a mate. Their 3 pairs of eyes each face a different direction. One faces in the direction they normally travel which is backwards. The next pair face upwards and look out for aerial predators. If a predators tries to attack they can flip over and block them with their hard shell. And the last pair of eyes are their main eyes for feeding. They are still herbivores and will take advantage of floating marine flora in the water. They will scoop them up with their tiny clawed hands and then will eat it on their chest. Females will lay frog-like eggs in the water which stick to the bottom of their shells. Once they hatch the tadpoles will follow their parents and feed on any scraps of food that drop into the water. They have gills until they reach adulthood in which they grow nostrils and then float on their backs.
