Frogs used for illegal doping in horse racing
Racing regulators kept hearing the reports: trainers were giving their
horses a powerful performance-enhancing potion drawn from the backs of a
type of South American frog.
But for months postrace testing could not find the substance, a
painkiller far more powerful than morphine. Then a lab in the Denver
area tweaked its testing procedure, and in recent weeks more than 30
horses from four states have tested positive for the substance,
dermorphin, which is suspected of helping horses run faster.
“We hear about some pretty exotic stuff,” said Dr. Steven Barker, who
directs the testing laboratory at Louisiana State University. “Frog
juice — this is exotic.”
The discovery comes as the racing industry is struggling to counter
perceptions of a pervasive drug culture. Indeed, dermorphin is the
latest in a long list of illegal performance-enhancing drugs that have
found their way onto racetracks. Cobra venom has also been used by
trainers to deaden pain so that injured horses can race.

No tadpoles here
Carrying out his fatherly duty, a male Oreophryne frog in Papua, New Guinea, guards his clutch and two newly hatched froglets that rest atop the egg mass.
Like many of the Microhylidae
family, these frogs bypass the tadpole stage, developing fully within
the egg.
Male frogs embrace their clutch each night to keep the eggs
moist and protect them from predators such as insects.
