Coelacanths are considered living fossils because they exhibit ancient features and characteristics that have remained relatively unchanged for millions of years, dating back to the Devonian period. Their unique skeletal structure, including lobed pectoral fins and a distinct braincase, closely resembles those of their ancestral species. Additionally, coelacanths were thought to be extinct for about 66 million years until a living specimen was discovered in 1938, providing a direct link to prehistoric marine life. This combination of ancient traits and survival through significant evolutionary periods makes them a remarkable example of a living fossil.
Coelacanths are carnivorous, feeding mainly on small fish and cephalopods. They are nocturnal hunters, using their sharp teeth to catch prey in the deep ocean waters where they live.
It was first thought that coelacanths only lived off steep rocky shores (where there are abundant refuge caves) at depths below 200 metres. We now know that coelacanths live in various habitats** and have been caught at depths ranging from about 15 metres to 600 metres. ** Rocky volcanic slopes of the Comoro Islands; rocky canyons and slopes with undercut terraces and some caves off the East African coast; amongst limestone/coral slopes off East Africa and Madagascar as well as similar habitats in Indonesia. At least three specimens have been trawled over muddy or sandy regions (South Africa, Mozambique and Malindi in Kenya). Hope this answers the question!
The group of fishes most closely related to ancestral amphibians are the lobe-finned fishes, which include the coelacanths and lungfishes. These fishes share certain characteristics with amphibians, such as limbs with digits and lungs or lung-like structures, indicating a close evolutionary relationship.
Physical similarities between two species are not always a result of the species being closely related. Linnaeus' system does not account for similarities that are evolved this way.
Coelacanths have been found off the coast of southern Africa near Madagascar.
sliths
Coelacanths eat whatever they find as they drift in the current. Because they can lift the upper jaw as well as move the lower jaw, coelacanths can open their mouths quite far to suck prey from crevices
Not really. In 1995, results from a dive counted about 40 coelacanths. The number has changed since then, but coelacanths are still nowhere near abundant. South African fisherman who fish for oilfish sometimes catch a coelacanth by accident. Without the strength to swim hundreds of meters back to their habitat, they usually die. Some of them get sold to scientists. As far as we know, coelacanths are very rare. Prior to around 1940, we thought they were extinct. They are still in danger.
The bony fish. They are also known as lobe-finned fishes.
it has been difficult to find Coelacanths because it lives depth range of 600- 1,000 feet under water and cause its in the Indian Ocean near Southern Africa.It was also called the missing link.
