Dolphin PPT
There are no bones in a dolphin's flukes, just tough connective tissue. The dolphin uses its flukes for swimming and its flippers for steering. Most dolphins have a boneless dorsal fin in the middle of their back that works somewhat like the rudder on a boat. Like the flukes, the dorsal fin does not contain any bones.
How deep do dolphins dive?
It's hard to say how deep oceanic dolphins can dive because most of the 32 species have not been studied. Bottlenose dolphins are shallow divers and typically don't go deeper than 150 feet. In the Indian River Lagoon the deepest waters are only 10 to 12 feet deep.
In the group of toothed whales, there are several subgroups:
oceanic doer dolphins :5 species sperm whales :3 species beaked whales :19 species beluga and narwhal :2 species

They are known for their impressive hunting techniques, such as herding schools of fish and swimming in coordinated patterns to corral their prey.

After birth, the mother dolphin takes great care of her calf, nursing and protecting it until it becomes independent.Unfortunately, dolphins face various threats in their natural habitats, including pollution, habitat destruction, and fishing nets. Conservation efforts are being made worldwide to protect and preserve these amazing creatures. Many countries have established protected areas and regulations to help ensure the survival of dolphins and their ecosystems.海豚是一种高度智能的海洋哺乳动物，属于海豚科。

DolphinDolphins are a species of small toothed whales. They are considered mammals because they are born with hair, have lungs (breath air), give live birth, nurse their young, are warm blooded and have larger, more developed brains than other animals. Dolphins are considered to be highly intelligent.BirthFemale dolphin are sexually mature at 8 years of age. They give birth every 2 - 3 years. This can happen any time of the year, but usually takes place in the Spring and Summer. SleepSince the dolphin are air breathers and must be aware of their surroundings at all times, they let half of their brain sleep at one time. They must remain at the surface of the water. First, they close one eye and allow one side of the brain to sleep, then they switch sides. The dolphin remains motionless during this time.EatingDolphins use 94 sharp teeth to eat fish and crustaceans. They consume 14 pounds of fish and crustaceans a day, and 20 pounds or more in colder months.Swimming and BreathingThe dolphin usually cruises at 7 miles per hour, but is capable of short burst of 30 miles per hour or more. They are able to dive to a depth of 1000 feet and can slow their heart rate, which allows them to stay under for up to 8 minutes at a time. Dolphin prefer to make shallow dives and take a breath every 2 or 3 minutes. They are able to leap from the water in a jump that reaches 20 feet.EcholocationEcholocation is a term used to describe the way dolphin use sonar or sounds to identify each other, food availability, and obstacles under the water. The dolphin makes clicking sounds, which rebound off of solid objects and echo back to the dolphin. When the rebounding click returns, the dolphin can identify what the object is and how far away it is by the amount of time it takes to return and the quality of the returned sound. This allows dolphin to communicate with one another at night and in murky water.DisplaysDolphin have a large range of displays. They appear playful as they leap from the water, one after the other, and roll about the waters surface.The coveThe Cove is a 2009 American documentary film that describes the annual killing of dolphins in a National Park at Taiji, Wakayama, in Japan from an ocean conservationists point of view.[2][3] The film highlights the fact that the number of dolphins killed in the Taiji dolphin hunting drive is several times greater than the number of whales killed in the Antarctic, and reports that 23,000 dolphins are killed in Japan every year。
