BUFO FOWLERI , Fowler's toad. This smaller toad is found along beaches, roadsides, 

 and in sandy areas where there may be shallow water in the central, east and northeast- 

 ern States. The adults measure not more than 3 inches in length. The general color is 

 green with middorsal light stripe. The male throat is black. The warts are generally 

 small, rounded and uniform, and generally at least 3 warts are enclosed in each dark 

 patch. Conspicuous shoulder glands, the parotids, are oval and long and in contact with 

 long ridges behind the eyes. Food the same as Bufo americanus. 



Breeding occurs from April to June, a little later than for Bufo americanus. About 8,000 

 eggs are layed in strings, each egg measuring about 1. to 1.2 mm. in diameter. The 

 metamorphic span takes about 40 to 60 days and is generally complete by August.
