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 ...

There are many strange creatures that we share the planet with, but cuttlefish are among the strangest. And in a stunning video from researchers intent on finding out more about them, their ...

Cuttlefish wave their expressive tentacles in four distinctive dancelike motions, a new study finds—possibly to communicate visually and by vibration. These marine invertebrates, which have ...

Cuttlefish may "wave" at each other with their tentacles to communicate, new research suggests.. But the study, which has not yet been peer-reviewed, didn't determine what messages the arm waving ...

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 ...

Now, nearly 20 years later, she still uses cuttlebone — the chalky internal shell of the squid-like cuttlefish — as molds for casting jewelry. Dried cuttlebone, when sanded, has a “unique ...
