Puffer fish

Tetraodon nigroviridis aka Puffer fish

Tetraodon nigroviridis also has some degree of value as a lab animal, in particular in the field of genetics, because it has the same number of genes as human beings but in a genome about one-tenth the size

Lots of fishy in this place. Too bad we spent too much time watching the otters take a bath that we missed the good seats over at the Dolphin show :(
Oh, I forgot to mention that there's also diff sorts of life there, like sea horses (alsmost missed this one, no pic :(), nemos (didn't see this one), frogs, snakes, perverted turtles, butterflies, monkeys, tarantulas, sea lion, beluga (& new born), crocs.
