Discocephali is an older taxonomic term that refers to a group of fishes, mainly remoras, characterized by their unique head structure. Imagine it like the 'scientific club' for fish with suction cups on their heads. These fish have a specialized disc on top of their heads that allows them to attach to larger marine animals. They hitch rides and scavenge food. The term isn't used much anymore, but it highlights a specific anatomical feature.
