This undated image released by McMaster University, shows a new species of African clawed frog. Scientists have discovered six new kinds of African clawed frog, and added back another to the list, boosting the number of known species by 30 percent and offering new avenues for research on human disease, said a study on December 16, 2015. The creatures are “most widely studied amphibians in the world”, and now there are 29 known clawed frog species instead of just 22, according to the study in PLOS ONE. African clawed frogs share a close evolutionary relationship with humans and are often used in biomedical research, including those involving genetic studies and cancer. The amphibians sport unusual claws on their first three toes, and reside in slow moving or stagnant water in west and central sub-Saharan Africa.
