Platypus

From the Paper:

"The platypus spends a great deal of time - ?most of [its] life,? according to Gould (1985, 14) - in the water, swimming, playing, and, principally, foraging for food. Adults can spend up to 12 or 14 hours continuously feeding, especially during breeding seasons (Fleay, 1944). During winter, their diets consist of various fly larvae, horsehair worms, and freshwater shrimp; in summer, shrimp and worms are replaced by still other types of fly larvae (Grant, 1989). The enormous amounts of food consumed by adult platypus have been a source of encumbrance in maintaining them in captivity: Fleay's Jill, weighing 2 lbs herself, was observed to consume 1.75 lbs of food in a single day (1944).
The platypus temperament presents a challenge to researchers hoping to study their habits. Platypus do not easily survive capture.."
