Bottlenose Dolphins Size They vary in size. How big they grow depends on where they live. Big males weigh over 1400lb in cold water. Males grow to 13ft in cold water. Females grow to more than 10ft in cold water. Both males/females grow from 8.5 to 8ft in warm water. Mating Females gain up to 100lbs while pregnant. Usually are bred and give birth from late spring to late summer. Males visit female groups to look for mates. After mating the males will leave in search of other mates. Food They are fond of fish,eels,squid,octopus,crab,lobster,mullet,and catfish. An active bottlenose needs to eat 10-30lbs of food a day. Bottlenose dolphins are carnivores.

Snacking is another way they chase the fish until they can grab it. Range The only places bottlenose dolphins can't be seen doing acrobatic leaps are the frigid polar seas.
