Repetitions and Duplications

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.
