Chimaeras


Chimaeras are named after a mythical Greek she-monster which had the head of a lion, combined with the tail of a dragon or a serpent, and the body of a goat.

Chimaeras
While chimaeras are evidently not a mixture of these creatures, there is probably that they are odd-looking fish. On account of they look a small such as sharks, they are moreover in some cases called apparition sharks. Unlike most sharks, however, chimaeras are weak swimmers, especially since they do not possess a “normal” fish tail. The most powerful fins in these fish are the pectorals (chest fins), which are shaped like fans. They use their fins to propel themselves along.

Special Features
ChimaerasChimaera teeth develop throughout the fish's essence, as they do in rodents for example rats and rabbits. There are several sets of teeth that likewise look a small such as those found in rodents, giving rise to the other common names, ratfish and rabbitfish. The teeth are fused together to form three crushing plates, one in the lower jaw and two in the upper jaw. These teeth are very tough and are used to crush the shells of the creatures that form their diet.

Chimaeras
Chimaeras tend to be found in deep, cold water where light levels are very low. They adapt to the aforementioned conditions by having truly great eyes. They can also track down food by smell and by using special sensory organs to detect their prey’s electrical impulses.
