It may be possible to increase melatonin levels by adding certain foods to the diet that contain this hormone. One study explains that all plant foods include Melatonin at differing levels. Some plant foods that include more Melatonin than others are rice, tomatoes, walnuts, barley and olives.
The Maryland Zoo in Baltimore houses African elephants (Loxodonta africana) who are very different from their Asian elephant (Elephas maximus) cousins. The African elephant (Loxodonta africana) is the largest land animal in the world.he forest elephant is generally smaller, with rounder ears, and tusks that grow downward. Normally, forest elephants inhabit the rain forests of central and western Africa and do not overlap the territories of the savannah elephant.
Two species are traditionally recognised, the African elephant (Loxodonta africana) and the Asian elephant (Elephas maximus), although some evidence suggests that African bush elephants and African forest elephants are separate species (L. africana and L. cyclotis respectively).he elephant's penis can reach a length of 100 cm (39 in) and a diameter of 16 cm (6 in) at the base. It is S-shaped when fully erect and has a Y-shaped orifice. The female has a well-developed clitoris at up to 40 cm (16 in). The vulva is located between the hind legs instead of near the tail as in most mammals.
