The sucking disc begins to show when the young fish are about 1 cm (0.4 in) long. When the remora reaches about 3 cm (1.2 in), the disc is fully formed and the remora can then attach to other animals. The remora's lower jaw projects beyond the upper, and the animal lacks a swim bladder. [9] Some remoras associate with specific host species.
One of the whalesucker's most outstanding traits, shared among the Echeinedae family, is an adhesive disk. The adhesive disk is a round, oval, sucking disk located on the top of a remora's head, with two layers of lamellae that allow for the remora to stick and unstick to the epidermal surfaces of larger fish, mainly cetaceans.
The common remora (Remora remora) is a pelagic marine fish [3] belonging to the family Echeneidae.The dorsal fin, which has 22 to 26 soft rays, acts as a suction cup, creating a vacuum [4] to allow the fish to attach to larger marine animals, such as whales, dolphins, sharks, and sea turtles.

Think of it as the advertising version of the symbiotic relationship between sharks and their parasite-eating remora. “We grew last year in a linear environment. There’s something to be said ...
When attached to a host, the remora eats parasitic crustaceans, food scraps from its host's feeding activity, and even some small food captured by filtering water through its villiform teeth. [ 11 ] Without a host, the fish stays close to the shore and can aggregate with other individuals; its diet is then composed of free-living crustaceans ...
Remoras (also called suckerfish) can swim freely but have evolved suckers that enable them to adhere to smooth surfaces, gaining a free ride , and they spend most of their lives clinging to a host animal such as a whale, turtle or shark. [3] However, the relationship may be mutualistic, as remoras, though not generally considered to be cleaner ...
The whale discovered in July is believed to be a male and is the seventh specimen of this species ever found. In 2010, the first intact specimen was discovered when a mother and calf were stranded ...
