This is a baby Pygmy Seahorse. The big black eyes made it look like a creature spawned from a science fiction movie. It is both cute and creepy.
There are many seahorse breeding programs in the world, however, not all had success due to the critical conditions the seahorses need to be in. This picture is an example of a very successful one. Bred in Steinhart Aquarium, this rare Bargibat's Pygmy Seahorse is among the first of its species to be hatched and cared for in captivity.
