A defining characteristic of the cuttlefish, the cuttlebone is a porous internal shell that helps control buoyancy, making it functionally similar to swim bladders in fish. Cuttlebones have both ...

Cuttlefish also have an internal structure called a cuttlebone that allows them to conserve energy by helping to keep them buoyant. The cuttlebone is a long, oval bone filled either with gas or ...

Cuttlebone is made of aragonite, a porous form of calcium carbonate, and helps the animal maintain buoyancy and protects its organs. The smallest of the roughly 120 species of cuttlefish is the 3- ...

In the ocean, the cuttlefish uses cuttlebone as a hard buoyancy tank to control its movement up and down the water column, to depths as low as 600 meters. The animal adjusts the ratio of gas to ...

"Cuttlebone in the scaffolds or in the capsules ... one of the tasks was removal of the traces of the protein tropomyosin found in cuttlefish muscle tissue, which amino sequence is slightly ...

Grasse hypothesizes that the behavior could have something to do with the size of the flamboyant cuttlefish’s cuttlebone, a calcium carbonate structure in the upper portion of the mantle cavity.

There are many strange creatures that we share the planet with, but cuttlefish are among the strangest. And in a stunning ...

With a powerful beat of her tail and a twist of her body, she jabbed downwards with a sharp thrust that killed the cuttlefish instantly. The thrust breaks the cuttlebone, a hard structure inside ...

Studying two species, common cuttlefish ( Sepia officinalis) and dwarf cuttlefish ( Sepia bandensis ), the two researchers have identified four arm-waving signs, which they call “up,” “side,” “roll” ...

This internal shell in the cuttlefish is known as the cuttlebone. Standing on the beach, I snap one in half. The cuttlebone is hard, but the internal structure is fragile, revealing a honeycombed ...
