摘要

All snakes are carnivorous and often represent the dominant predatory species in food chains of terrestrial and aquatic communities. Snake food habits, feeding behavior, and tropic ecology have been extensively documented (Mushinsky, 1987). Food lists on the dietary preferences of North American snakes can be found in virtually any study on snake ecology. Snakes often eat a variety of vertebrate prey (often including snakes themselves [e.g., see appendix in Greene, 1988]); vertebrates constitute the principal component of the diet in 95 of 116 snakes species (82%) reported by Mushinsky (1987). Only recently has the snake diet literature begun to emphasize foraging theory and the interrelationships between predator and prey (see review by Arnold, 1993).
