In a commensal relationship, one organism benefits while the other is unaffected. By attaching itself to a leopard shark, a remora is carried along on the shark's power. This allows the remora to “travel” to different areas without having to expend its own energy to swim. The shark is completely unaffected by the remora's presence.
