Smell and behavior: The scents of taking action

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.

'Junk DNA' uncovers the nature of our ancient ancestors

The key to solving one of the great puzzles in evolutionary biology, the origin of vertebrates -- animals with an internal skeleton made of bone -- has been revealed in new research from Dartmouth College and the University ...

Lampreys provide hints to ancient immune cells

Studying lampreys allows biologists to envision the evolutionary past, because they represent an early offshoot of the evolutionary tree, before sharks and fish.

Sea lampreys jettison one-fifth of their genome

(PhysOrg.com) -- Researchers have discovered that the sea lamprey, which emerged from jawless fish first appearing 500 million years ago, dramatically remodels its genome. Shortly after a fertilized lamprey egg divides into ...

Human rules may determine environmental 'tipping points'

A new paper appearing in the Proceedings of the National Academy of Sciences (PNAS) suggests that people, governments, and institutions that shape the way people interact may be just as important for determining environmental ...

Sea lampreys turning up the heat

(Phys.org) —Male sea lampreys may not be the best-looking creatures swimming in our lakes and streams, but they apparently have something going for them that the ladies may find irresistible.

Lamprey

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.
