Ctenophore

 
 ctenophores (ten-o-for) are not realy a jellyfish, but they are related to jellyfish.  Like jellyfish, they have jelly-like bodies with a circular or radial design, but they have no stinging cells.  There are about a hundred speices of comb jellies.  The largest are up to 5 feet (1 . 5m) in diameter, but most are very small- about an inch ( 2 . 5 cm) across.  Most comb jellies are transparent- which makes it difficult ror their prey to see them- but some deep-sea speices are brightly colored.  This small ctenophore may not look scary, but it has caused a lot of damage in some parts of the world.  It eats so many fish eggs and other small animals that larger predators do not have enough to eat.
