Waaaa!! Now it seems clearer! =)
1. Lobsters, like grasshoppers, feel no pain. They have a decentralized nervous system with no cerebral cortex, which in humans is where a reaction to painful stimuli proceeds.
2. You can cut up a starfish into pieces, and each piece will grow into a completely new starfish.
3. Starfish have eyespots at the tip of each arm. These act as light sensors and contain a red pigment that changes chemically in the presence of light. The eyespots are believed to influence the starfish’s behavior, particularly movement.
4. Dolphins do not breathe automatically, as humans do, and so they do not sleep as humans do. If they became unconscious, they would sink to the bottom of the sea. Without the oxygen they need to take in periodically, they would die.
5. Dolphins swim in circles while they sleep, with the eye on the outside of the circle open to keep watch for predators. After a certain amount of time, they reverse and swim in the opposite direction with the opposite eye open.
6. Dolphins have killed sharks by ramming them with their snouts.
7. Some sharks swim in a figure eight when frightened.
8. Sharks can be dangerous even before they are born. Scientist Stewart Springer was bitten by a sand tiger shark embryo while he was examining its pregnant mother.
9. Lemon sharks grow a new set of teeth every two weeks. They grow more than twenty-four thousand new teeth every year.
10. Seals can sleep underwater and surface for air without even waking.
11. Seals must teach their young how to swim.
12. The hippopotamus gives birth underwater and nurses its young in the river as well, although the young hippos must come up periodically for air. Hippopotami cannot swim.
13. The fastest dog, the greyhound, can reach speeds of up to forty-five miles per hour. The breed was known to exist in ancient Egypt more than five thousand years ago.
14. Jackals have one more pair of chromosomes than dogs or wolves.
15. To safeguard its food when away, the wolverine marks it with a strong musk so foul smelling that other animals won’t touch it.
16. Very unusual for carnivores, hyena clans are dominated by females.
17. The elephant is the only mammal that can’t jump.
18. Elephants perform greeting ceremonies when a member of the group returns after a long time away. The welcoming animals spin around, flap their ears, and trumpet.
19. There are more than 150 breeds of horses in the world.
20. Rhinos are in the same family as horses and are thought to have inspired the myth of the unicorn. A rhinoceros’s horn is made of compacted hair.
21. A geep is a cross between a goat and a sheep.
22. The only purple animal is the South African Blesbok.
23. The world’s smallest mammal is the bumblebee bat of Thailand, weighing less than a penny.
24. The longest recorded life span of a camel was thirty-five years, five months.
25. Camel’s milk does not curdle.
26. The giant armadillo has as many as one hundred teeth, although they are small and fragile.
27. Giant tortoises can live to be 150 years old or older.
28. The gender of a sea turtle is determined by the temperature of the sand during egg incubation. Warm temperatures produce more females; cooler temperatures produce more males.
29. Skunks have more than smell to protect themselves. They can withstand five times the snake venom that would kill a rabbit.
30. The hedgehog has a large muscle running along its stomach so it can pull its lithe body into a tight, prickly little ball for defense.
31. An armadillo can walk underwater.
32. The koala is one of the few land animals that does not need to drink water to survive.
33. It takes a sloth two weeks to digest the food it eats.
34. Carnivorous animals will not eat another animal that has been hit by a lightning strike.
