Candy Crab - Hoplophrys oatesi

Candy CrabHoplophrys oatesi – A very colorful crab that grows from 1.5 to 2 cm. It lives on various species of soft coral in the #Dendronephthya genus. It camouflages itself by mimicking the colors of the polyps among which it hides. It adds further camouflage by attaching polyps to its carapace. Colors vary depending on the color of the coral, and may be white, pink, yellow or red.

The first pair of legs of this species has small claws. The body has pointed spines with a red and white pattern, similar in appearance to the host coral.

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.
