This article was originally posted at Amazing Zoology Did your ever realise that microscopic mites live on your face and entire body through out the life time? These mites called Demodex live its entire life in the skin and pores of humans and other mammals. Of the identified 65 species, two species live on your face, they are Demodex folliculorum and Demodex brevis . Two species live in slightly different areas, D. folliculorum lives in pores and hair follicles and D. brevis prefers to live deep inside your sebaceous glands. The adult mites are only 0.3–0.4 mm long, with  D. brevis  slightly shorter than  D. folliculorum . These mites are mostly seen associated with the face as the face has larger pores and more sebaceous glands. They are also seen else where in the body including genital area and breasts.

Whales are the largest living organisms living on the surface of Earth. An adult blue whale weighs up to 173 tonnes with 30 meters in length. [1] When a whale dies in the ocean, its body usually falls to the sea floor and becomes a huge source of organic matter for the animals that live there. This is known as a Whale fall.

Stingrays can chew their food, like mammals

This article was originally posted at Stingrays can chew their food, like mammals [toc] Is chewing a unique mammalian feature? Unlike mammals, other animals usually don’t have the ability to chew their food. Chewing can be defined as the interaction of upper and lower teeth by compressing and shearing food in between. And the peculiarity of mammalian chewing is the opposable motion of upper and lower jaw. Chewing is a very recent evolutionary adaptation. There are a few animals along with mammals to do that. Chewing is estimated to have evolved some 60-70 million years during the diversification of mammals. Some scientists even believed chewing one of the key innovations that allowed mammals to flourish, by dining well on insects, grasses, and other abundant sources of food. Now, recent findings using high speed videography has given scientific evidence to show that chewing is not just a mammalian adaptation. Recent study [1]  reveals that ocellate river stingray ( Potam...
