Among the extant animals, there are also many species that are contemporaries of dinosaurs, and even some species are older than the dinosaur era, such as the coelacanth, which is an ancient species. Recently, on the coast of Madagascar, fishermen have mistakenly caught a rare fish, which is an ancient fish - coelacanth, and finally handed this fish to the relevant units for research.
According to reports: this coelacanth is accidentally caught by the lensnet, the lentillin is a deep-sea fishing net, when the glitternet is opened vertically in the sea, just wait for the fish to swim in, the fish will be entangled in the net, it is difficult to escape, many deep-sea creatures will be caught by the net, which is a great threat to the survival of deep-sea species.
The last coelacanth will be used for research, in fact, there are statistics: coelacanth is rare in other places, but in the coastal areas of Madagascar, the chance of catching coelacanth is also very large, as many as 100 coelacanths are caught, indicating that this area of Madagascar may be the habitat of coelacanth populations, but this also shows that the barbed net is also a great threat to the survival of coelacanth populations, so the fishing method may affect the survival of coelacanth populations or other deep-sea species.
In marine life, coelacanth is not just a fish, but a collective term for some leaf-finned teleost fish, which are also very ancient species, according to fossil research: coelacanth first appeared 377 million years ago, coelacanth history is earlier than dinosaurs.
Because it was difficult to find the traces of coelacanth for a period of time, it was once believed that coelacanth was extinct about 60 million years ago, in fact, the coelacanth population is mainly distributed in the deep sea of the Indian Ocean, and in some places it is used as a food fish, such as in the Comoros Islands, they usually salt the fish meat of the cavannah fish to be salted and dried to eat, and the coarse scales are used as abrasive, which is a common edible fish in the eyes of the local islanders.
Coelacanths are of great research value, for example, in the evolution of species, it is believed that many land animals are from the sea, and coelacanths can use their fins to walk as feet, which is important evidence for the evolution of fish to amphibians. At the same time, coelacanth has been included in the "near-threatened" species protection list, banning the trade of coelacanth and protecting this rare ancient fish!
