An Ecological Study of Snails of the Genus Busycon at Beaufort, North Carolina

“…A proteolytic enzyme has been demonstrated in Busycon saliva (Mendel and Bradley 1905). A proteolytic enzyme has been demonstrated in Busycon saliva (Mendel and Bradley 1905).…”

“…Adult animnals appear to be exclusively carnivorous. The enzymes of this snail are of the types that would be expected in an animal with a high percentage of protein foods (Mendel and Bradley 1905). The foot of Busycon is broad and flat; its structure permits the animal to move with apparent effortlessness over shifting sand and soft mnud in search for food.…”

“…Shells of Pelecypods that have recently been eaten by Busycons, or those that are in the procrss of being eaten, are always covered with a thick, sticky material, probably saliva. A proteolytic enzyme has been demonstrated in Busycon saliva (Mendel and Bradley 1905). In fact this is the only protease found throughout the digestive tract of this genus.…”

“…Many of the earlier workers (Mendel and Bradley 1905, Herrick 1906, and Rogers 1920 suggested that Busyeons obtained their food by boring a hole through the shell and sucking out the soft parts for food. The process by which an animal obtains and ingests its food is of fundamental importance in determining its food, and even habits and habitats.…”

“…The process by which an animal obtains and ingests its food is of fundamental importance in determining its food, and even habits and habitats. Many of the earlier workers (Mendel and Bradley 1905, Herrick 1906, and Rogers 1920 suggested that Busycons obtained their food by boring a hole through the shell and sucking out the soft parts for food. Colton (1908) corrected this erroneous impression when he observed Busycons as they ate food in a laboratory tank.…”
