Stumpy Cuttlefish – Dwarf Cuttlefish – Sepia bandensis
This weird and wonderful cuttlefish is not actually a fish but is in fact a mollusk. They have an internal shell (cuttlebone), amazing large W-shaped pupils, eight arms and two tentacles which they use for feeding.
This little fellow was smooth a few moments before and then bumped himself up changed color from almost white to this tan, a true ‘chameleon of the sea’.
Oooh! A Side-gilled slug – Pleurobranchus forskalii – gills are found on the right side of the body in the gap between the mantle and the foot. This relatively large pleurobranch is often found in quite large populations in shallow lagoons, reef crests and pools and sea grass beds.
The Funeral Nudibranch – Jorunna funebris, gets is name from the black and white coloration. It feeds on a blue sponges (Neopetrosia sp.), which makes it poisonous, and able to secrete chemicals that make them distasteful or toxic.
As a members from the family Discodorididae they are able to retract its gills into a gill pocket. Many species are able to break off part of their mantle to distract predators. They generally have a narrow foot compared to the wide mantle skirt.
Introducing Huenia heraldica, the Halimeda Crab. Its ability to camouflage in Halimeda algae (duh!) is nothing short of remarkable.
Halimeda algae is a smart object to mimic since very few organisms enjoy dining on this hard algae.
This species is a decorator crab; It sometimes attaches rigid fronds of halimeda algae to its rostrum in front of the eyes to enhance its camouflage.
The Devil Scorpion Fish – Scorpaenopsis diabolus, the false stonefish is a carnivorous ray-finned fish. It has venomous spines and is a bottom-dwelling predator that relies on its camouflage to catch passing prey. The inner sides of the broad pectoral fins have orange, black, and white blotches and the fins can be “flashed” as a warning.
Originally spotted using an ultra-violet light. They exhibit biofluorescence, that is, when illuminated ultraviolet light, it re-emits it as red, and appears differently than under white light.
Biofluorescence may assist in intraspecific communication and camouflage.

A face a mother may not love. They always scares the crap out of me when I see one, especially when they crawl around on their ventral fins.
Ornate Ghost Pipefish – Solenostomus paradoxus. The species name comes from the Greek paradoxos, referring to this fish’s unusual external features.
