Unusual nests and places

Unusual nests and places: you’d never think of this one!

Nests to shelter eggs, the young of a species and its parent(s) are constructions that are being employed by a wide range of very different animals. Nests may be made entirely from material that is produced by the nest maker alone as, for example, in spiders that spin a cocoon to house their eggs or as in anabantoid labyrinth fishes like the Siamese fighting fish and the South American catfishes of the genus Hoplosternum, which construct nests of air bubbles that these fish spit into a pile that then floats on the surface of the water.

Tongue Twisters

To train our tired tongues tremendous tricks

A look at the tongue and an experienced physician can diagnose dermatoses, diabetes, liver ailments, stomach disorders and other diseases quite easily. But the tongue is more than a mirror of our health (and for some people an organ that has to tolerate piercing – a custom dating back to pre-Columbian Amerindian Maya and Aztec cultures). It lets us taste, possesses the best two-point discrimination of any body region, is tremendously sensitive to temperature and most of all it lets us speak. Trying to say “Peter Piper picked a peck of pickled pepper” or “A proper copper coffee pot”, your tongue twists and it twists because of a remarkable arrangement of nerves and longitudinal, transverse, circular, and oblique muscle fibres. —>—>
