Gestation time is the length of time that it takes from fertilization to birth.
mammalWhales have all the characteristics of mammals they: perform internal fertilization, produce milk for their young, breathe air, have hair (as fetuses), and are endothermic vertebrates.
Tigers have Internal Fertilization. (occurs inside the body). Tigers copulate frequently and noisily and repeatedly for 5 or 6 days. Each usually take about 20 to 30 seconds. Then the gestation period is 16 weeks.
During external fertilization, many gametes are released into the water by each sex at the same time and place. This type of fertilization requires water because animal sperm must swim to the eggs. Water also protects the gametes from drying out. Species which have external fertilization are either aquatic or return to water for reproduction.
