Coelamon is an Ancient Fish Digimon whose name and design are derived from the coelacanth (Latimeria chalumnae). It possesses gigantic talons and a hard outer skin. When the Computer Network was being repaired after being disrupted by a malicious hacker, this Digimon was discovered in the Net Ocean, and as its body structure is extremely primitive, it has fins that have developed like hands and feet. Based on this fact, it is conjectured that primeval Digimon that originated in the Net Ocean experienced many digivolutions and took on terrestrial forms, and increased their numbers into various strains.
