Comment: Against dolphin captivity
The average life span of a dolphin in the wild is 45 years; yet half of all captured dolphins die within their first two years of captivity. The survivors last an average of only 5 years in captivity.
When a baby dolphin is born in captivity, the news is usually kept secret until the calf shows signs of survival. Although marine mammals do breed in captivity, the birth rate is not nearly as successful as the one in the wild, with high infant mortality rates.
Wild dolphins can swim 40 to 100 miles per day – in pools they go around in circles.
Many marine parks subject their mammals to hunger so they will perform for their food. Jumping through hoops, tail walking and playing ball are trained behaviors that do not occur in the wild.
When trapped together, males often become agitated and domineering. This creates pecking orders (unknown in the wild) and unprovoked attacks on each other and the trainers. In the ocean, although fights are not unknown, the wild dolphins have a chance to escape.
