Boas and Pythons of the World. When in captivity, feeding them every two weeks with mice is a sufficient diet. They do not have external ears. breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female, defends an area within the home range, occupied by a single animals or group of animals of the same species and held through overt defense, display, or advertisement. An introduced population exists in extreme southern Florida,[25] and a small population on St. Croix in the U.S. Virgin Islands now appears to be reproducing in the wild.
