Coelacanth

Often regarded as a creature of myths, this fish is a large species known for its unique respiratory adaptation, with nostrils that open into the oral cavity, enabling it to breathe air. Its robustly developed pectoral and pelvic fins are so strong that they allow the fish to crawl on land. Inhabiting the deep and distant seas, this fish is notoriously difficult to catch, but its rarity and unique characteristics make it highly valuable.
