It is not known to evolve into or from any other Pokémon.
Relicanth is a Pokémon that is heavily based on the coelacanth. It is covered with hard, brown scales that are similar to craggy rocks. The composition of its scales and fatty body allow it to withstand the intense pressure of the ocean depths. Its tan head has protruding cheekbones, which are smaller on a female. A triangular spike protrudes from the back of its head. Tan patches cover its body and there is a red spot located on both sides. It possesses two pairs of pectoral fins, which it uses to push itself along the sea bottom. Additionally, it has dorsal and pelvic fins near its tail. Its tail fin has a wavy outline. Relicanth is a filter feeder, and it feeds on microscopic organisms with its toothless mouth. It has remained unchanged for 100 million years, and stays as such because it is already a perfect life-form.

Relicanth shares many similarities with Fossil Pokémon, in the sense that it is also part-Rock-type, has a gender ratio of seven males to one female, and it is referred as an ancient Pokémon in some Pokédex entries.
Relicanth are based on the coelacanth, an order of fish that was thought to be extinct. They are considered living fossils because they are virtually unchanged from their prehistoric forms. Like their real-life counterpart, Relicanth were thought to have gone extinct 100 million years ago until they were recently rediscovered in a submarine exploration. Relicanth matches the Indonesian coelacanth in color, but its Shiny coloration is like that of the more well-known West Indian Ocean coelacanth. It may also take inspiration from placoderms, an extinct class of fish with armored heads.
Relicanth may be a combination of relic (something old that has survived the passage of time), relict and coelacanth.
Glanth may be a combination of 爺 jī (old man) and coelacanth.
