Denise's pygmy seahorse

Denise’s pygmy seahorse, also known as Hippocampus denise, lives among the coral reefs of the western Pacific at depths of 40 feet to 300 feet. It stands around 1/2 inch tall and is considered one of the best-camouflaged fishes in the oceans. Previously, the animal was mistakenly thought to be a juvenile of another of the 32 known species of seahorses. Pygmy seahorses, which are typically 10 times smaller than non-pygmy relatives, were first discovered in the late 1960s.
