Potbelly Seahorse, Hippocampus bleekeri Fowler, 1908

Scientific name: Hippocampus bleekeri
Similar species:
The Potbelly Seahorse looks similar to the Bigbelly Seahorse, Hippocampus abdominalis. The two species can be separated by the Bigbelly Seahorse's shorter snout, the more common presence of head filaments in the Potbelly Seahorse, and their disjunct distributions.

Introduction

About the Potbelly Seahorse

The Potbelly Seahorse is one of the largest species of seahorses, growing to 30 cm in length. It has more tail rings than any other seahorse species, a low coronet, and as the common name implies, adults have very big 'bellies'. The colouration of the Potbelly Seahorse is variable. It can be grey, brown, orange, yellow. It often has dark spots and long filaments on the head or body. The colouration appears correlated with habitat.
