Comparison of A–C Hippocampus colemani in situ, Green Island, Taiwan with D–F Hippocampus pontohi in situ, Green Island, Taiwan. Note the differences in the shape and angle of the coronet (low and rounded in H. colemani vs. distinct and angular in H. pontohi), as well as differences in body colouration (H. colemani is known only to occur in shades of off-white, whereas H. pontohi is highly variable) (Photographs A Joe Chiu B Ryan Ku C, E, F Ming-Hung Yu D Ryan Ku).
