Definition
- Noun:
- A family of marine fishes: Echeneididae is the scientific family name for a group of fish commonly known as remoras or suckerfish. These fish are characterized by a unique, modified dorsal fin that forms a flat, oval-shaped sucking disk on the top of their head.
- Fishes with a specialized clinging organ: The primary defining feature of this family is the presence of this adhesive disk, which they use to attach themselves to larger marine animals like sharks, rays, turtles, and whales, or even to ships and other objects.
Usage Examples
- Noun:

- Marine biologists study the symbiotic relationships between members of the Echeneididae and their hosts.
Advanced Usage
