Hi gang, I have an extra beautiful Caribbean reef octopus clinging to a colony of mountainous star coral for you all today that I found late at night on our house reef.  The Caribbean reef octopus (Octopus briareus) is a coral reef marine animal. It has eight long arms that vary in length and diameter. The mantle is large and chunky in comparison (up to 60 cm long). This species is difficult to describe because it changes color and texture to blend into its surroundings, using specialized skin cells known as chromatophores. Its color range is very large; it can change from crimson to green, and bumpy to smooth. It weighs around 3.3 lb or 1.5 kg.

The Caribbean reef octopus lives in hidden, rocky lairs that are difficult to locate. Their lairs are usually created in shallow warm waters. O. briareus is not a social animal, and stays at a safe distance from other octopuses of the same species, except for mating. MORE
