Are coelacanths dinosaurs?
The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years, a new study found. Coelacanths, which have been around for 400 million years, were thought extinct until they were found alive in 1938 off South Africa. Scientists long believed coelacanths live about 20 years.

How old is the coelacanth?
360 million years
Fossils description Coelacanths are known from the fossil record dating back over 360 million years, with a peak in abundance about 240 million years ago. Before 1938 they were believed to have become extinct approximately 80 million years ago, when they disappeared from the fossil record.
How many coelacanths exist?
two
There are only two known species of coelacanths: one that lives near the Comoros Islands off the east coast of Africa, and one found in the waters off Sulawesi, Indonesia.
Are coelacanths still alive?
Coelacanths reside at ocean depths of as much as half a mile (800 meters). The two extant species, both endangered, are the African coelacanth, found mainly near the Comoro Islands off the continent’s east coast, and the Indonesian coelacanth.

Are coelacanths going extinct?

Coelacanth/Extinction status
What fish went extinct in 2020?
Smooth handfish (Sympterichthys unipennis)—One of the few extinctions of 2020 that received much media attention, and it’s easy to see why. Handfish are an unusual group of species whose front fins look somewhat like human appendages, which they use to walk around the ocean floor.
What is the oldest fish in the world?
the Greenland shark
As for the current holder of the record for oldest fish in the sea, it’s the Greenland shark. A 2016 study examining these cold-water sharks’ eyes found one female estimated to be nearly 400 years old—good enough to hold the record for the oldest known vertebrate not just under the sea but anywhere on the planet.

Why are coelacanths important to vertebrates?
As rare as they are today, lobe-finned fish like Coelacanths constitute an important link in vertebrate evolution. About 400 million years ago, various populations of sarcopterygians evolved the ability to crawl out of the water and breathe on dry land.
