Timestamped Summary
00:00
The celacanth, a fish that has been around for 400 million years and was thought to be extinct, was rediscovered in the 1930s.
04:37
The celacanth, a fish that was thought to be extinct, was rediscovered in the 1930s by a trawler off the coast of South Africa, and its identification was made possible by the preservation of its scales.
09:21
The coelacanth, a fish that was thought to be extinct, was rediscovered in the 1930s and named Latimeria chelumne after the woman who found it, and it was later discovered in Indonesia as well.
14:02
The coelacanths have not changed much over time because they have stayed in the same environment and have not needed to evolve quickly, and the areas where they live now are not conducive to fossilization.
18:43
Coelacanths are deep water dwellers that live in the twilight zone of the ocean, are nocturnal hunters, and have a unique rostral organ in their snout that detects low-level electrical signals and frequencies from prey.
23:26
Coelacanths have unique features such as a notochord, which is a hollow pressurized tube filled with oil, and their mode of reproduction is called ovoviviparity, where the eggs develop and hatch inside the female for a three-year period before being born, and there is a theory that they are monogamous.
28:27
Coelacanths have unique features such as a notochord, ovoviviparity, and a theory of monogamy, and they were long thought to be the missing link between fishes and land-dwelling animals.
33:10
Coelacanths have a high fat content, with their brains occupying only 1.5 percent of their skull, and they also have vestigial lungs that serve no purpose in adulthood.
38:06
Living fossils include the bow fin, dogfish, mudfish, gar, hagfish, and sturgeon, each with their own unique characteristics and behaviors.
