Digital Calendar photo description
Colourful Cuttlefish
While diving deep on Giants Castle reef off Tofo, Mozambique, the photographer glided along a sponge‑encrusted reef wall hoping for Manta Rays to swim overhead. This Cuttlefish was curiously investigating the photographer, while blending with the background of the reef. The Cuttlefish is able to flash different colours and designs and uses this, plus its well known intelligence and good eyesight, to remain undetected or, if need be, use jet propulsion to make a rapid getaway
Cuttlefish - Sepia latimanus
Cuttlefish are marine animals of the order Sepiida belonging to the class Cephalopoda (which also includes squid, octopuses, and nautiluses). Despite their name, Cuttlefish are not fish but molluscs. Recent studies indicate that Cuttlefish are among the most intelligent invertebrates. Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates. The origin of the word Cuttlefish can be found in the old English term cudele, which derived in the
15th century from the Norwegian koddi (cushion, testicle) and the Middle German kudel (pouch), a good
description of the cephalopod's shape. Cuttlefish have an internal shell (the cuttlebone), large W-shaped pupils, and
eight arms and two tentacles furnished with denticulated suckers with which they secure their prey.
