What is the cause of deformed frogs?

The variations in malformation suggest multiple causes are involved in this worldwide problem; four major causes that have been identified include injuries from predators, a specific parasite (fluke), nutritional deficiencies, and contaminants.

What is a deformed frog?

What three environmental factors can cause frog malformations?

Three environmental factors considered responsible for malformations are ultraviolet (UV) light from the Sun, chemical contaminants, and parasites. Research supports the notion that UV light may be sufficient to cause major developmental changes in amphibians.

What causes a frog to be deformed on the left?

Many of them look as if they had been exposed to retinoids. The frog on the left was captured in the field from a confirmed deformed frog locality. The frog on the right is a lab-raised frog whose deformity was caused by an attack by a fellow tadpole during its limb development. (Courtesy of Dr. Stanley Sessions, Hartwick College)

When did malformation of frogs become a problem?

Malformed frogs first came to national attention in 1995. Since that time, reports of malformed frogs and other amphibians have increased dramatically. Malformations have been reported in at least 44 states and in more than 50 species of frogs and toads. Multiple limbs, missing limbs, and facial abnormalities are the main malformations seen.
