Overall, the passage is a collection of interesting and little-known facts about various animal species, presented in a humorous and engaging way.
Here are the key facts extracted from the text:
1. The sound of the lion in the MGM logo is actually the roar of a tiger.
2. Tigers have a louder and more intimidating roar than lions.
3. The "Majestic shaking call" of the bald eagle in movies is actually the sound of a red-tailed hawk.
4. The dolphin sound from SpongeBob is actually a sped-up edited call of the Australian bird called a Kookaburra.
5. Mufasa's roar in The Lion King was made by combining the sounds of a tiger, an F-16 fighter jet, and a grizzly bear.
6. Longhorn beetles are known for their loud, high-pitched sound, which is often described as "Satan's plumbing."
7. Longhorn beetles are one of the biggest threats to trees, as their larvae feed on plant tissue and can destroy trees from the inside.
8. Adult Longhorns will girdle tree branches to create a nursery for their young.
9. Asian longhorn beetles are an invasive species in America, causing over $600 billion in damage.
10. Seagulls are known to eat almost anything, including rabbits, other birds, and even small mammals.
11. Seagulls have been observed attacking and killing sheep, baby seals, and even other seagulls.
12. Rhinoceroses are related to horses and have sensitive skin and feet.

14. Rhinos have poor eyesight, but have a keen sense of smell and hearing.
15. The Gharial is a type of crocodile that is native to India and Nepal and has a distinctive long, thin snout.
16. Gharials are endangered due to habitat loss, pollution, and hunting.
17. The Siberian unicorn, also known as the Elasmotherium, is an extinct species of rhinoceros that lived during the Ice Age.
18. The Elasmotherium had a distinctive horn made of keratin, the same protein that makes up human hair and nails.
19. Zebras are actually black with white stripes, not the other way around.
20. Zebras have a unique striping pattern that is like a fingerprint, no two zebras have the same pattern.
21. Hibernation is a state of inactivity and reduced metabolism that some animals enter to conserve energy.
22. True hibernators, such as chipmunks, experience a significant drop in body temperature, heart rate, and metabolism during hibernation.
23. Bears do not truly hibernate, but rather enter a state of torpor, which is a period of reduced activity and lowered body temperature.
24. Cuttlefish have 3D vision and use it to judge distances and catch prey.
25. Scientists have used 3D glasses to study the vision of cuttlefish and found that they use stereopsis to perceive the world.
