Coelacanths are thought to be the ancestors of terrestrial vertebrates, and are estimated to have appeared as early as 377 million years ago, when they were widely distributed on Earth.
The fish was thought to have gone extinct for a long time, until its sudden discovery in African waters in 1938.
Coelacanth is a large carnivore with a long lifespan, and the growth rate of coelacanth is very slow, the female coelacanth does not mature until the age of 50, and the male does not mature until the age of 40. Coelacanths can have a gestation of up to five years. Organisms with long growth cycles are vulnerable to climate change and human activities, and the conservation of coelacanth is currently underway, and the international trade in coelacanth has been banned.
As a deep-sea fish, coelacanth can be described as a food that does not refuse, so it can be called an omnivorous fish. Plankton in the ocean is generally the staple food of coelacanths, and some small fish that are significantly weaker than coelacanths will also become the meal of coelacanths.
In some cases, coelacanths can also become aggressive, preying on well-being fish and deep-sea fish such as manta rays. It also eats plants such as seaweed and seaweed.
