This frog (Breviceps namaquensis) sounds like a bike horn.

Not one to be outdone by the dynamic trio of Alvin, Simon, and Theodore of Alvin and the Chipmunks, the least chipmunk (Eutamias Minimus) is the smallest of all chipmunk species (shown above). Least chipmunks range over most of western North America occupying the widest geographic and altitudinal range of any chipmunk. These tiny rodents possess a long, narrow but fairly bushy tail, and have soft, dense fur which is moulted twice a year - the summer coat being brighter in color than the more greyish winter coat. Like other chipmunks, this species has relatively short ears which are covered in short hairs and pouches inside the cheeks which are used to carry food. Interestingly, the female least chipmunk may be slightly larger than the male ...

After watching this incredible footage, I can't help but notice the similarities between humans and chimpanzees - it's quite fascinating!

Stingrays are ovoviparous, meaning that the eggs develop and hatch inside the mother, who then give birth to live young. They have between 5 and 13 offspring at a time. Before birth, the female holds the embryos in the womb without a placenta. Instead, the embryos absorb nutrients from a yolk sac, and after the sac is depleted, the mother provides uterine "milk".
