“Amphibian horror” isn’t a movie genre, but on this evidence perhaps it should be. Harvard biologists have described a bizarre, hairy frog with cat-like extendable claws.

Trichobatrachus robustus actively breaks its own bones to produce claws that puncture their way out of the frog’s toe pads, probably when it is threatened. . . . Read Complete Report

Australian scientists have successfully revived and reactivated the genome of an extinct frog. The “Lazarus Project” team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog.

The extinct frog in question is the Rheobatrachus silus, one of only two species of gastric-brooding frogs, or Platypus frogs, native to Queensland, Australia. Both species became extinct in the mid-1980s and were unique amongst frog species for the way in which they incubated their offspring. After the eggs were fertilized by the male, the female would then swallow the eggs until they hatched. The tadpoles would then develop in the female’s stomach for at least six weeks – during which time the female would not eat – before being regurgitated and raised in shallow water. . . .
