Angel Shark
Angels and Sharks don't normally go together, but as sharks go this one is definitely an angel.
These sharks are completely harmless and spend most of their time buried in the sand waiting for their next meal to stumble a little too close. The imprint they leave behind in the sand looks just like a snow angel. We're not too sure how they got their name, but this might be the reason.
They look more like rays than sharks, but their gills are on the side of their body rather than the underside. This is how you can tell that a creature is a shark and not a ray.
