Pahanin makes light of the marine biological description of the working internals within the ship. He sees humor in the cephalopod related word term used.

Definition Summary

Cuttlefish: A cephalopod related to squids and octopus. Intelligent animals which have a ring of arms surrounding their head, a beak made of chitin and interior flattened oval internal skeleton/shell a.k.a. cuttlebone.

Cuttlebone: a chambered, gas-filled shell used for buoyancy control; its siphuncle is made of tiny narrow layers connected by numerous upright pillars. Giving the ability to fly and glide through the ocean.

Siphuncle: (in shelled cephalopods such as nautiloids and ammonoids) a calcareous tube containing living tissue running through all the shell chambers, serving to pump fluid out of vacant chambers in order to adjust buoyancy. 

Some facts about cuttlefish:

♦ Over 100 species of cuttlefish exist. They vary in size from 3 inches to several feet in length. The giant cuttlefish is the largest cuttlefish species and can grow to over 3 feet in length and weigh more than 20 pounds.

♦ Cuttlefish are cephalopods and are related to octopus, squid, and nautilus. They are intelligent animals with a ring of arms surrounding their head, a beak made of chitin, a shell (only the nautilus has an exterior shell), a head and foot that are merged, and complex shaped eyes.

♦ Cuttlefish have two long tentacles that are used for grappling prey, it can then manipulate using its arms. Both the tentacles and arms have suckers.

♦ Cuttlefish have a fin that goes around their body, which looks like a skirt. They use this fin for swimming. When quick movement is needed, they can expel water and move by jet-propulsion.

♦ Cuttlefish are active predators who feed on other mollusks, fish, and crabs. They may also feed on other cuttlefish. They have a beak in the middle of their arms that they can use to break the shells of their food.

♦ Cuttlefish change color to match the surroundings, especially when threatened. Millions of pigment cells, called chromatophores, in their skin that can shift and reflect colors, even the pattern on its skin can be changed.

♦ Cuttlefish have ink called sepia and can be released in a cloud that confuses predators providing opportunity to escape. This ink historically was used for writing and drawing, can be used to treat medical conditions and is also used as a food coloring.

♦ Cuttlefish have a long, oval bone called a cuttlebone used to regulate buoyancy via internal chambers that may be filled with gas or water. This gives them the ability to glide and fly through the ocean. Cuttlebones have a high calcium/mineral content and are used as a supplement for many pets.

♦ Cuttlefish are blind to color but they can see polarized light. To focus on an object, a cuttlefish changes the “W” shape of its eye, allowing them to control reflective light and perceive it’s surroundings.
