👉 Cryptocephalinae is a group of small, round-shaped fish that are commonly found in freshwater and brackish water bodies around the world. They have a long, slender body with a single tentacle (also known as the caudal fin) extending from their head. Cryptocephalinae are primarily terrestrial species, but some can also be aquatic. These fish are often associated with saltwater habitats and are important prey for many marine animals.
