The Mating Game Notes Eastern Gray tree frog Located: Eastern North America Habitat: Small trees/ shrubs by shallow bodies of waters Reproduction: Males attract females using a flute like trill, when the females are ready to lay their eggs, males and females climb to the pond to mate. Females can have up to 2,000 eggs Growth: Tadpoles become young frogs in eight to 10 weeks. By summer's end, young frogs have left the pond to begin feeding in trees and shrubs alongside the adults African Elephant Location: Sub-Saharan Africa Habitat: primarily savanna but also bush and forest habitat Reproduction: Males maintain a complex dominance hierarchy outside the matriarchal society of the females. Growth: After mating, gestation usually lasts about 22 months -- the longest gestation period of any mammal. Females generally give birth to one calf, which if male leaves the herd at 12 to 15 years of age, and if female remains with the herd for the duration of her 60- to 70-year life span. Uganda kob Location: Central Africa Habitat: floodplains and other well-watered areas Reproduction: ales defend territories on courtship arenas called leks. An average lek about 200 meters in diameter will contain about 15 circular territories, each defended by a male. Males patrol their territory's boundary, whistling loudly in an attempt to attract females. Growth: Gestation lasts for about nine months, after which the female gives birth to one offspring on average. Green Tree frog Location: Eastern North America Habitat: Low vegetation very near constant water sources Reproduction: Males use a nasal croak to attract females. When eggs are mature, the females enter the water and are clasped by the males in a process called amplexus. As the female lays the eggs, the male fertilizes them externally. Growth: Tadpoles transform into adults after about two months.
