Smiling Marine Reptile
This animal uses its grooved flippers to hold on to the slippery rocks on the shores of its home planet. It is an air-breathing reptile that lives in salt water and eats mostly seaweeds, though it may rarely snatch up an odd crab or two.
It has poor vision, but partly makes up for this with the row of chemoreceptors on its upper lip.
When threatened, it will roll into a ball with its dorsal osteoderms facing outwards.
