Main Ref. Wetherbee, B.M., S.H. Gruber and E. Cortes, 1990
Remarks Exhibits no pattern of periodicity. Feeding is asynchronous and intermittent. Daily ration is estimated at 1.5 - 2.1% body weight per day; meal completely evacuated from stomach 25-41 hr after feeding, depending on meal type and temperature; fecal production continues for 68-82 hr after feeding (Wetherbee 1990).
