Caribbean Reef Octopus

The Caribbean reef octopus (Octopus briareus) is moderate sized (ML < 120mm), with long arms (4 to 6 times mantle length), and characteristically loose webbing that is both deep and thin (almost billowing), which it uses to envelope coral heads, rubble, and prey, as well as an iridescent blue-green color pattern (Jereb & Roper, 2005).
