What is Chimaer?
Chimaer is a type of fish considered to be one of the oldest still existing. Chimaeras mostly deep water consists of over 40 different species scattered around the world. Chimaer, also known as Ghost Shark, Ratfish or Rabbitfish, has had many interesting features over the years.
Originally, the species of Chimaer emerged from the same ancestor as sharks, but at least 400 million years ago distinguishes. They are considered somewhat related to other cartilage species such as rays and skates. Just as sharks remain a cartilage group that has a skeleton made of hardened cartilage, but not bones. Unlike their shark cousins, however, these fish have molten upper jaws and molten dighters that look like incisors of rodents or rabbits, ie nicknames Ratfish or rabbit.
Although many species have variations, most of Chimaeer is recognizable by their long, slender tails and wide flat heads. Some have bright green eyes or dloA bit tapered muzzle. The color varies according to the species, with most brown to silver gray. Some, such as spotted rats, have a brown overall color distributed with white spots.
as well as sharks and rays have smooth skin and no scales. Sizes differ between different species, with some, such as the deep living Chimaera, reaching up to five feet (1.52 meters) in length. Females are generally significantly larger than men. Males have a distinct connecting organ near the fins used to hold larger women during mating. Cases of Chimaer eggs are clear and have a leather egg case in the shape of a spindle.
Somewhat dangerous to a person, Chimaer has a spine or fin that can be used for defense. If they are attacked or grabbed, the fish can raise this spine to avert predators. Not all kinds of this unusual spine, but serves as an excellent defense mechanism for many drUsům Chimaer.
Despite their deadly poison, people injuries are rare due to extreme depth in which many of these creatures are dwelling. While several species prefer coastal waters of slight depth, most live in much depth of the world's oceans, often descends up to 8500 ft (2.59 km) near continental shelves. Since the deep sea research has expanded due to improved submarine technology, many new Chimaer species have been found in deep places, bringing the total number of different types of Chimaer to more than 40.
