Abstract
The methods used in the breeding and rearing of Peltophryne lemur along with comments on reintroduction efforts are described. Breeding was induced by injections of leutinizing releasing hormone, and fertile eggs were produced. Eggs hatched in approximately 24 h. Newly hatched tadpoles were small (5.0 mm) and delicate. Metamorphosis occurred in 20–30 days, and newly metamorphosed toads grew evenly and quickly to maturity in about 1 yr. Seventy‐five 20‐mm young were returned to Puerto Rico in May 1983. These toads were released at a pond where adult and young P lemur were seen. The successful maintenance and breeding of this species indicate it can survive in captivity. Future work on P lemur should concentrate on its status and survival in the wild.
