View original article at http://amzoo.in/w2bzo © Copyright Royal Belgian Institute of Natural Sciences Among the newely discovered 26 species of amphipods of genus Ephimera from Southern Ocean off Antarctica, one species stood out for its humped back. It was named Epimeria quasimodo and is about 2 inches long. It was named for Victor Hugo’s character, Quasimodo the hunchback, in reference to its somewhat humped back. Extraordinary morphological structures and colors, makes the genus Epimeria an icon of the Southern Ocean that includes both free-swimming predators and sessile filter feeders. The genus is abundant in the glacial waters circulating south of the Polar Front and their crested adornments are reminiscent of mythological dragons. Suggested Reading 1.

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...

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.
