They are commonly found attached to sharks, manta rays, whales, turtles, and dugongs, hence the common names "sharksucker" and "whalesucker". Smaller remoras also fasten onto fish such as tuna and swordfish , and some of the smallest remoras travel in the mouths or gills of large manta rays, ocean sunfish , swordfish and sailfish .
The sea lamprey has an eel-like body without paired fins. Its mouth is jawless, round and sucker-like, and as wide or wider than the head; sharp teeth are arranged in many concentric circular rows around a sharp, rasp-like tongue. There are seven branchial or gill-like openings behind the eye. Sea lampreys are olive or brown-yellow on the ...
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]
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.
Blenniformids are generally small fish, only occasionally reaching lengths up to 55 cm, with elongated bodies (some almost eel-like), and relatively large eyes and mouths. Their dorsal fins are often continuous and long; the pelvic fins typically have a single embedded spine and are short and slender, situated before the pectoral fins.
The frilled shark's lower jaw has 21–29 rows of recurved, needle-like teeth, for snagging, capturing, and eating soft-bodied cephalopods, small sharks, and bony fish. The eel-like bodies of C. anguineus and C. africana differ anatomically; C. anguineus has a longer head and shorter gill slits, a spinal column with more vertebrae (160–171 vs ...
An example of a flabby fish is the cusk-eel Acanthonus armatus, [58] a predator with a huge head and a body that is 90% water. This fish has the largest ears and the smallest brain in relation to its body size of all known vertebrates. [59] Robust benthopelagic fish are muscular swimmers that actively cruise the bottom searching for prey.
A similar strategy has been employed by fish in the presence of large reef sharks, as they use the larger animal as a tool to ambush prey. [46] The opportunistic nature of giant trevally has also been made evident by studies on the mortality rate of undersized or egg-bearing lobsters released from traps at the water's surface of the Hawaiian ...
