An illustration of two platypuses by John Gould (1863).
Here, Gould focuses on the bill, webbed feet, and thick tail of the platypus. In the lower right, a platypus is in a curled posture (adopted while sleeping and likely to be the position a female adopts while incubating her eggs).
This sketch was completed during a trip that Gould made to Australia from 1838-1840.
