Side Gilled Slug – Pleurobranchus forskalii

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.

Halimedia Crab - Huenia heraldica
I blend in

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

Devil Scorpion  Fish - Scorpaenopsis diabolus

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.
