A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the blind, filter-feeding larvae of modern lampreys are a holdover from the distant ...

In all animals, including humans, smell—the oldest of the five senses—plays a predominant role in many behaviors essential for survival and reproduction. It has been known since ancient times that animals react to odours.

Lamprey are blood-sucking vampire-like fish that attach to and eventually kill game fish, making them the bane of many a fisherman's existence. Like something out of a horror film, these parasites use radial rows of sharp ...

(Phys.org)—A team of researchers with members from several institutions in Japan has developed a new way to edit genes that involves cutting just one strand of DNA rather than both of them, as is normal for CRISPR-Cas9. ...
If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire evolutionary ...

A sea lamprey has no jaw, no proper teeth and no bones. Yet this predator can attach like a suction cup to a fish 100 times its size, use its tongue to burrow a hole into its side, liquefy its tissues and eat it.

It's a mystery. Invasive sea lamprey, the Great Lakes' biggest predator, primarily feed on lake trout, one of the lakes' most prized sports fish. When trout populations are high, researchers expect to see fewer lamprey-wounded ...

Geotriinae Mordaciinae Petromyzontinae
Lampreys (sometimes also called lamprey eels) are a Predator family of Jawless fish, whose adults are characterized by a toothed, funnel-like sucking mouth. Translated from an admixture of Latin and Greek, lamprey means stone lickers (lambere: to lick, and petra: stone). While lampreys are well-known for those species which bore into the flesh of other fish to suck their blood, most species of lamprey are non-parasitic and never feed on other fish . In zoology, lampreys are sometimes not considered to be true fish because of their distinctive morphology and physiology.
