  2. These are some animals you can find in the ocean:

  3. Dolphins Here are some interesting facts about dolphins: 1. Dolphins have life expectancy of about 40 to 50 years. 2. They eat several kinds of fish and squid. An average adult dolphin will eat 22 to 50 lbs of fish each day. 3. Dolphins can sleep in several ways, such as swimming slowly and surfacing for air, floating at the surface with the blowhole exposed, or rest on the bottom of shallow water and rise to the surface every now and then to breath.

  4. Dolphins (continued) Here are some more interesting facts about dolphins: 1. The deepest dive ever recorded for a dolphin was 990 feet. Dolphins do not normally dive very deep. They tend to stay in relatively shallow water. 2. Even though dolphins live in the ocean, they do not drink the water. It is too salty for them to drink. The water they get comes from the food, the fish and squid they eat. When they metabolize their fat, their kidneys retain as much water as possible.

  5. Whales Here are some interesting facts about whales: 1. The largest whale is the blue whale, who can grow to over 100 feet. 2. The heart of an average whale weighs 1,750 lbs. The brain of an average whale weighs 12.5 lbs. 3. A whale’s lungs can store up to 5,000 liters of air.

  6. Whales (continued) Here are some more interesting facts about whales: 1. While eating, the skin stretches so that when it opens its mouth, water is filtered, and food is retained. 2. Whale pregnancies last 2-3 years. 3. Whales never travel alone. They are found in groups of 2-10.

  7. Seals Here are some interesting facts about seals: 1. Seals are able to dive 1000 feet, and can stay underwater for 30 min. 2. They have more blood for their body size than any other land animal. 3. They come on land or ice to mate.

  8. Seals (continued) Here are some more interesting facts about seals: 1. Seals propel themselves with their rear flippers. They steer with their front flippers. 2. A seal’s milk is forty-five to fifty percent fat. 3. Some seals, due to their mother’s fatty milk, add almost 3 lbs a day until they are around 3 weeks old.

  9. Stingrays Here are some interesting facts about stingrays: 1. Stingrays are usually found in shallow coastal temperate water. 2. They spend the majority of their time inactive, partially buried in the sand, often moving only with the tide. 3. The eyes are found on the top, while their mouth, nostrils, and gills are located on their belly.

  10. Stingrays (continued) Here are some more interesting facts about stingrays: 1. Since stingrays cannot see their mouths, they use electrical sensors located around the mouth to search for potential prey. 2. They have jaw teeth that allows them to crush hard prey, such as clams, oysters, and mussels. 3. Most stingrays move their body like a wave in order to swim. Others flap their sides like wings.

  11. Sharks Here are some interesting facts about sharks: 1. Sharks shed and replace their teeth constantly. Some species shed up to 30,000 teeth in their lifetime. 2. The average life span of a shark is 25 years, but some sharks live to be 100. 3. Sharks have no bones. Their skeleton is made up of cartilage.

  12. Sharks (continued) Here are some more interesting facts about sharks: 1. There are more than 340 known species of sharks. 2. Sharks first appeared in the fossil record over 400 million years ago. 3. Sharks can generate about 6.5 tons per square inch of biting force. 4. A sharks skin is filled with dermal dentils, which resemble teeth.

  13. Manatees Here are some interesting facts about manatees: 1. The average adult manatee is about 9.8 feet long and weighs between 800-1,200 lbs. 2. Manatees can be found in shallow, slow-moving rivers, estuaries, saltwater bays, canals, and coastal areas. 3. They are gentle and slow-moving. Most of their time is spent eating, resting, and traveling.

  14. Manatees (continued) Here are some more interesting facts about manatees: 1. Manatees are completely herbivorous. They eat aquatic plants and can consume 10-15% of their body weight daily in vegetation. 2. On average, a manatee will come up to breathe every 3-5 minutes, unless they are exerting a lot of energy, in which they will surface every 30 seconds. When resting, they have been known to stay submerged for 20 minutes. 3. The life span of manatees is about 60 years.

Dolphins get their water consumption from the salt water of the ocean. • How long do whale pregnancies last? • A mother seal’s milk can contain around how much percent fat? • What do stingrays use to hunt for prey? • True or False. Sharks have no bones. • Manatees have a life span of about how many years?

  17. Answers • False. They get it from the fish and squid they eat. • 2-3 years. • 45-50% fat. • Electrical sensors located around their mouth. • True. Their skeleton is made up of cartilage. • 60 years.
