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.

This article was originally posted at Amazing Zoology For the first time in history, scientists have recorded a full-fledged conversation between two bottlenose dolphins. It was known for years that dolphins use very complex language to communicate each other. But it is the first time we get clear evidence to say they are stringing together words to create sentences and even have grammar, a recent study [1] says. What was the experiment? Signals produced by dolphins are classified into five different types. Of these, ‘mutually noncoherent pulses’ or ‘NPs’ were considered for the current study. The experiments were performed on two adult Black Sea bottlenose dolphins (Tursіps truncatus), named Yasha (male) and Yana (female), in a closed concrete pool. The speech patterns were recorded using waterproof Hydrophones places in the pool. The recordings of these dolphins were saved and analysed using various techniques.
