Different fish swim by undulating different parts of their bodies. Eel-shaped fish undulate their entire body in rhythmic sequences. Streamlined fish, such as salmon, undulate the caudal portions of their bodies. Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
Fish, like these yellowfin tuna, use many different mechanisms to propel themselves through water. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and ...
In British folklore, the monster known as the Lambton Worm may have been based on a lamprey, since it is described as an eel-like creature with nine eyes. [citation needed] In Japanese, lamprey are called yatsume-unagi (八つ目鰻, "eight-eyed eels"), thus excluding the nostril from the count. [citation needed]
The reedfish is nocturnal, and feeds on annelid worms, small crustaceans (such as shrimp), insects (both adults and their larvae), snails and small fish. [4] [10] [15] When moving through water slowly, it tends to use its pectoral fins, changing to an eel-like form of swimming (making more use of full-body movements and the caudal fin) when ...
The silver lamprey is an eel-like fish with an attenuate body composed of 49–52 clearly defined segments (i.e. myomeres, between the last gill slit and the anus).Silver lampreys possess a cartilaginous skeleton, and adults generally grow to a length of 12 inches and are silvery or bluish in color when spawning.
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups.Ambiguous common names are accompanied by their possible meanings.
Ridley Scott’s “Gladiator II” is full of memorable action scenes, from a bloody showdown featuring CGI baboons to Paul Mescal outsmarting a charging rhino in the Roman Colosseum.
The remora (/ ˈ r ɛ m ə r ə /), sometimes called suckerfish or sharksucker, is any of a family (Echeneidae) of ray-finned fish in the order Carangiformes. [4] Depending on species, they grow to 30–110 cm (12–43 in) long.
