A dinosaur fish, also known as a coelacanth, is a type of lobe-finned fish that has been around since the Devonian period, over 400 million years ago. Unlike other types of fish, coelacanths have a unique combination of characteristics that set them apart, such as their fleshy fins, which resemble the limbs of tetrapods, and their robust, heavy bodies.

Dinosaur fish are not actually related to the dinosaurs that roamed the Earth millions of years ago; rather, they share a common ancestor with them. Remarkably, coelacanths survived the mass extinction event that wiped out the dinosaurs around 66 million years ago and are still alive today. They are considered a living fossil, providing valuable insights into the early evolution of vertebrates.

Coelacanths are typically found in deep-water environments along continental shelves and slopes, at depths ranging from 150 to 700 meters (500 to 2,300 feet). They prefer cold waters and are often found near undersea caves and crevices where they can hide from predators.

The size of dinosaur fish can vary significantly among species. The most well-known species, *Latimeria chalumnae*, can grow up to about 1.5 meters (5 feet) in length and weigh up to 90 kilograms (200 pounds). Another species, *Latimeria menadoensis*, tends to be slightly smaller, reaching lengths of up to 1 meter (3.3 feet).
