📖 Overview

Only known to occur on gorgonian corals of the genus Muricella, with up to 28 pairs on a single gorgonian. The tubercles and truncated snout of this species match the color and shape of the polyps of the host gorgonian, while its body matches the gorgonian stem. So extreme is this camouflage that the original specimens were only noticed after their host gorgonian had been collected and observed in an aquarium. Post-pelagic young settle on various hosts, but to breed, they appear to prefer the red polyp Muricella spp. That usually grow in depths over 20 m . Ovoviviparous . The male carries the eggs in a brood pouch which is found under the tail . Minimum depth reported taken from Ref. 128812.
