Notes on the Feeding Behavior and Caudal Luring by Juvenile Alsophis portoricensis (Serpentes: Colubridae)

Field observations of mating behavior in the neck-banded snake Scaphiodontophis annulatus (Serpentes: Colubridae).

We observed the mating behavior of the neck-banded snake Scaphiodontophis annulatus (a common species of colubrid in the South Pacific of Costa Rica) in the pre-montane wet forest of Las Cruces Biological Station (San Vito de Java, Costa Rica).

Effects of Prey Type on the Feeding Behavior of Alsophis portoricensis (Serpentes: Colubridae)

Alsophis portoricensis can inject the secretion of its Duvernoy's gland (=venom) into its prey, constrict it, or swallow it alive. We studied the differences in prey-handling behavior of Alsophis portoricensis when feeding on two of its natural prey species, the lizard Anolis cristatellus and the frog Eleutherodactylus coqui. Subduing time was higher for lizards, but swallowing and handling tim...
