The Fun and Weird Side of Animal Behavior: 5 Facts You Didn’t See Coming!

5 Fun (and Sometimes Not-So-Fun) Animal Facts

Animals are full of surprises—some are cute, and others are just plain wild. Today, I’m sharing five quirky facts about our animal friends that will make you see them in a whole new light.

1. Cats: Killing for Fun?

Yes, our beloved house cats (Felis catus) aren’t just hunting for food or survival; they actually kill for fun. Studies show that domestic cats kill billions of small animals each year, including birds, mammals, and reptiles. Researchers estimate that cats kill around 1.3 to 4 billion birds and 6.3 to 22.3 billion mammals annually in the United States alone​ Their instinct to hunt is deeply ingrained—even well-fed cats will go after prey purely for entertainment. So next time your kitty brings home a “gift,” remember it's all in good fun for them, albeit not so fun for their prey.

2. Tigers Roar Louder Than Lions

Think you’ve heard a lion's roar in the movies? Think again! It’s more likely that the sound you’re hearing is a tiger. Tigers have the loudest roar of any big cat, reaching up to 114 decibels—louder than a jet engine at takeoff! In many films, especially older ones, tiger roars were used because they sound more dramatic. The average lion's roar, while impressive, typically ranges around 110 decibels .

3. Elephants Worship the Moon

Elephants are known for their intelligence and social complexity, but did you know they seem to exhibit a form of moon worship? On nights of the full moon, elephants have been observed to exhibit peculiar behaviors—gathering in herds, lifting their trunks toward the sky, and seemingly gazing at the moon. This phenomenon is not fully understood, but researchers believe it could be related to their advanced memory and social bonds . There are theories, but the mystery adds to their mystique.

4. Octopuses: The Ultimate Escape Artists

Octopuses are famous for their intelligence, but did you know they’re also masters of escape? These cephalopods have three hearts, blue blood, and the ability to squeeze through incredibly tight spaces. Their soft bodies allow them to compress themselves to fit through gaps as small as a quarter, and they’ve been known to break out of aquariums and slink away undetected​

One of the lesser-known facts about male octopuses is that they can detach their reproductive arm (called the hectocotylus) to escape aggressive mates. Some species of male octopuses leave their detachable arm with the female, which continues the reproductive process even after the male swims away Now that’s a dramatic exit!

5. Moose vs. Killer Whales?

You probably know moose can swim, but did you know they are excellent deep divers? Moose are capable of diving up to 20 feet (6 meters) underwater to feed on aquatic plants like pondweed and water lilies . But here’s where it gets crazier: There have been reports of moose getting into tussles with orcas, also known as killer whales, while diving in coastal waters off Alaska! While this might seem like an urban legend, there have been rare cases of orcas attacking swimming moose .

I had a blast writing these! Special shout-out to my girlfriend, fellow animal nerd, for helping me gather these fun tidbits. Got any other wild animal facts I might’ve missed? Hit me up and let me know! Stay tuned for more animal facts next week.
