Cuttlefish are intelligent and clever predators. They hunt near the bottom and do so quickly. They are counted, along with the perhaps slightly more famous octopus, among the cephalopods. They are less spectacular when it comes to changing their body shape, but they have reached perfection in changing their colour.

What colour they have at the moment depends on many factors. Camouflage allows cuttlefish to remain invisible to their surroundings, especially to enemies, but also to passing food. However, their colour also depends on their mood.

When studying cuttlefish, it has been observed that the curious and at the same time cautious one changes colour, as if it could not decide what to put on today. Changes in colouration also depend, for example, on the desire to impress a mate and then the colour of the males is very intense and they fight for the females.

A feature common to cuttlefish and octopuses is the fact that they have a melanoma sac, which is filled with sepia (a dark brown substance) that is fired when threatened.

Cuttlefish, also known as sepia, have a spindly and oval body, a distinctive visceral sac with two non-joining fins, and a head section with large eyes and grasping arms.

In males, one or two of the arms are transformed into a copulatory organ called hectocotylus (used to place spermatophores in the female’s mantle cavity). They have an internal skeleton reduced to a shell (os sepiae) called the cuttlefish bone. This is a hard calcareous formation found on the dorsal side under the mantle.

The dorsum itself is sometimes covered with unevenly spaced appendages, and the cuttlefish’s possession of an inner shell limits its ability to change shape. The mouth is located between the shoulders, surrounded by a lip, and has two cuticular jaws. See for yourself how skilfully these predators hunt.
