  1. Atlantic Bottlenose Dolphin Tursiops Truncatus By: Lindsey Gonzales Seth Cunningham

  2. “There’s no place like home!” • In the Atlantic Ocean, bottlenose dolphins are found from Nova Scotia and Norway to Patagonia and the tip of Southern Africa. They are the most abundant dolphin species along US from Cape Cod through the Gulf of Mexico.

  3. Survival of the Fittest ; How Dolphins Survive • Dolphins are carnivorous and they are active predators.Their natural predators are sharks and occasionally killer whales. • They migrate when resource supplies are low and when the climate changes.

  4. Can swim at “burst” speeds of up to 18-22 mph but on average swim 3-7 mph. Dolphins breath oxygen by surfacing 2 - 3 times a minute, but can hold their breath for 5 - 10 minutes. Dolphins dive regularly to depths of 10 - 150 ft., but the best trained can dive 1,795 ft. Survival continued …

  5. Dinner Time ! • Dolphins eat fish and squid. Some types are mullet, sea trout, but they’re not picky. They eat almost any kind of fish. • Dolphins eat approx. 4% to 5% of their body weight per day. An average Atlantic Bottlenose weighs 419 - 573 lbs, so that means they eat 20.95 - 28.65 lbs. of food every day!

  6. Dinner Time continued… • Dolphins cooperate with each other when it’s time to hunt. Dolphin pods herd large schools of fish into small dense masses and then slap the masses with their tail flukes. It then stuns the fish and the dolphins feast. • Dolphins swallow their food whole.

  7. “Awe, how cute!”Dolphin Babies • Dolphins reproduce sexually. • Female dolphins are pregnant for about 12 months. • A dolphin can calve ever 2 years but generally calves every tree years.

  8. A mother dolphin is very protective of her child and usually only lets the assisting dolphin near the baby. A baby dolphin nurses for up to 18 months. Baby dolphins learn everything from their mom. Within a few days of birth, a baby calf can vocalize. Dolphin babies continued...

  9. “Your getting so big!” • A baby dolphin is about 42-52 in. long and weighs 44lb. • Adult dolphins are about 8.2- 8.9 ft. long and weigh between 419- 573 lb.

  10. Long live the dolphins! • A dolphins average life span is probably 20 years or less. • Bottlenose dolphins have lived as long as 48 years.

  11. Endangered Species? • Bottlenose dolphins are NOT endangered! • In the Gulf of Mexico, there is estimated to be at least 67,000. • In the western North Atlantic, the bottlenose population is estimated at about 11,700.
