    What does this look like to you?



    It's a harp sponge. Most sponges filter ocean water for bacteria but this one has velcro like barbs on it's branches which grab tiny crustaceans as they swim past. Since sponges don't have a digestive cavity, the prey is surrounded by digestive cells which slowly digest it.
