Tuesday, May 2, 2023

Cuttlefish are the GOAT's of camouflage. They have the ability to blend into their environment by changing their color almost immediatly. Let's take a look at 10 facts about the Cuttlefish.

1. Cuttlefish belong to the class Cephalopoda which also includes squid, octopuses, and nautiluses.

2. Cuttlefish have large W-shaped pupils, eight arms, and two tentacles. 

3. They generally range in size from 15 to 25 cm (6 to 10 in), with the largest species, the giant cuttlefish being around 50cm 20 inches.

4. The average cuttlefish lives about 1–2 years.


5. Cuttlefish also have one of the largest brain-to-body size ratios of all invertebrates. In other words, they are smart.

6. Cuttlefish can be found in tropical and temperate ocean waters. They are found along the coasts of East and South Asia, Western Europe, the Mediterranean, as well as the coasts of Africa and Australia.

7. Cuttlefish like other cephalopods have the ability to produce venom, excreting it through their beak to help kill their prey.


8. Cuttlefish have the ability to rapidly alter their skin color.  Cuttlefish change color, the pattern and the shape of the skin to communicate to other cuttlefish, to camouflage themselves, and to warn off potential predators.

9. Cuttlefish use chromatophores within their skin to quickly change their color. Chromatophores are sacs containing hundreds of thousands of pigment granules which results in color change.


10. Despite their inability to perceive color, cuttlefish have the ability to detect their surroundings and match the color, and texture of their surroundings even in almost total darkness. We are not really sure how they do this.

Bonus : Cuttlefish like to feed on crabs and fish, they also feed on small shrimp.
