Latimeria, commonly known as coelacanth, is a prehistoric fish that was once thought to be extinct but was rediscovered in the 20th century. The name Latimeria is derived from the scientist who discovered the first live specimen, Marjorie Courtenay-Latimer. The coelacanth is often referred to as a "living fossil" due to its ancient lineage and unchanged appearance. Other synonyms for Latimeria include the gombessa, the Welshman, and the four-legged fish. Despite being a rare and mysterious creature, the coelacanth has captured the imagination of scientists and the public alike, and has become a symbol of conservation and resilience.
