As stated in the introduction/ interview segment, Georgia Aquarium proudly states that their profits received from ticket sales and other things are used for the caring of their animals. Compared to the size of the fish, the teeth are considered minuscule. Evidence indicates the pups are not all born at once, but rather the female retains sperm from one mating and produces a steady stream of pups over a prolonged period. whale shark lifespan in captivity.

Dr. Carson generously supported his response to the deaths of Ralph and Norton, and assured us that these deaths were not in any way correlated to maltreatment in the aquarium, so yes, I am satisfied with his statement.
