Myth: Felines and canines are colorblind

Although it was long believed that our furry companions had limited vision and only saw certain colors, it's not the case. Cats and dogs have much better color eyesight than we thought.

Both can see shades of blue and green. In fact, cats have way more light-sensing cells or rods in their eyes than humans do, and that's why they can see better in low-light situations. Of course that doesn't explain why they sometimes act that way they do. Here's some insight to explain your feline's behavior.

Admit it. You've crashed into a wall making your way to the bathroom during the night. That won't happen with a cat, felines: According to ScienceABC, they have an extra "mirror" layer at the back of their eye behind their retina, which means that the incoming light has two chances to hit the rods. In the human eye, if it misses, the light is absorbed in a black layer behind the retina, and is gone forever.

Pups have less color-sensing cells in their eyes so their color vision may be only 1/7th as vibrant as ours. According to the American Kennel Club, scientists believe that a dog's color vision is similar to that of a person who has red–green colorblindness.

Myth: Bees can only sting once

Unless you're like this couple who unexpectedly became honey bee entrepreneurs, you do your best to avoid winged stingers. With good reason: Bumble bees and yellow jacket wasps have mostly smooth stingers and can attack repeatedly. And if there's a European hornet that's buzzing around your yard, stay away! According to an article in Forbes, they don't even bother stinging you because they're large enough to bite with their jaws—yikes. And then there are good old wood bees that burrow holes in your wood deck or home. Stick a finger in there and a female may sting you. But you're safe if it's a male wood bee. Poor guys don't have stingers.

Turns out the only bee with a single sting is the honey bee. Once they get you, it's the big bee hive in the sky for them. Find out the intricate democracy that makes bees one of the 8 smartest animals in the world.

Myth: Male animals aren't nurturing

Although it's the female emperor penguin that lays the eggs, this mom takes off right after for a two-week ocean holiday to replenish nutrition levels. Who watches the kids while Mom is out regaining her strength? The poppa penguin, of course. Not only does he watch them, he actually holds the egg between the tops of his feet and his brooding pouch for those two months. He actually starves himself to prevent moving to avoid anything happening to his offspring. Now that's willpower.

Not to be outdone, Jacana fathers, another feathered friend, are also very giving of themselves. In fact, they hang around the nest long after the mommies take off for migration even taking care of eggs that were fertilized by other males.

Myth: Ducks can't fly

There are many more grounded birds than you might expect, but ducks aren't one of them. (They're also pretty good at staring contests, apparently.) Some wild ducks can actually fly 50 miles per hour, but most are much slower due to their heft. The reason ducks may have this reputation is the steamer duck, of which three out of four species are flightless. Even the ones who can fly don't always pull it off: Some of the males are too heavy to actually achieve lift off. According to Britannica, these South American ducks earned their name by running across water and thrashing their wings like the wheels on a steamboat. It's understandable that watching all your other duck pals fly off must be frustrating. Perhaps enough to give you anger issues as steamer ducks are known to be mighty aggressive, engaging in epic, bloody battles with each other over territory disputes. Don't feed the ducks takes on a whole new meaning when you consider steamer ducks have been known to kill waterbirds several times their size.

Myth: Touch a baby bird and mom will fly the coop

Did some crafty bird decide to give birth in a nest under your deck or porch? (And if they haven't, here are some tips to attract birds to your yard.) No you don't need to surround it with yellow warning tape to make sure no one touches the newborns. It's only folklore that birds will reject their young if humans touch them.

"If a bird's nest is disturbed by a potential predator during the nesting or egg-laying stage, there's a possibility that [it] will desert and re-nest," Frank B. Gill, former president of the American Ornithologists' Union, told Scientific American. "However, once the young are hatched and feeding, [their parents are] by and large pretty tenacious."

Birds can't detect human scents. Most have small and simple olfactory nerves limiting their sense of smell. But messing with the nest could still make your feathered friend flighty. "The fact is, birds don't abandon their young in response to touch, [but] they will abandon [their offspring and their nest] in response to disturbance," explains biologist Thomas E. Martin of the University of Montana and the U.S. Geological Survey, who has handled birds from Venezuela to Tasmania without instigating abandonment. "They are likely responding to disturbance in relation to risk of harm to young."

So when in doubt, hands off the nest is best.

Myth: The king of the jungle is a freeloader

Lions have gotten a bad rap for not helping out their ladies when it comes to hunting. But a new study reveals the king of beasts might be doing his share after all.

According to NBC News, by combining GPS collars that track lions' movements with airborne Light Detection and Ranging (LiDAR) measurements that provide 3-D maps of the landscape and vegetation, the research team was able to reveal that male lions are solitary predators who leap out of thick vegetation to ambush their prey. That's in contrast to the social hunting behaviors of lionesses that hunt in packs. And female lions live together for life. Their female cubs also stay with the pride, even after they're grown, but male cubs must venture out on their own once they reach maturity. So lions may still hunt as loners, but they're far from lazy.

Myth: Females are the only ones to get pregnant

If you're a seahorse that is. Turns out in this sea-faring family it's the guys who get pregnant and give birth to the young.

Male seahorses have a brood pouch where females deposit their eggs. He then fertilizes the eggs and incubates them for a period up to 45 days, when they emerge as fully developed little seahorses. The new seahorse fathers even experience muscular contractions as they give birth.

Seahorses get big when preggers—they can deliver 100 to 200 babies in one go. (Are you trying to lose baby weight? Here are some new workouts to try.)

Myth: Octopuses are just another dumb mollusk

If you saw Finding Dory, the Pixar movie that followed the smash hit Finding Nemo, you might recall Hank, an octopus that can change colors to blend in with his surroundings. Had Finding Nemo been scientifically accurate, it would have been a very different movie; however, a mimic octopus is a real thing. It's an octopus that can take on the appearance of other creatures like flatfish or sea snakes without needing them nearby to model. They just remember. But the mimic octopus is not the only smart octopus. There's the story of Inky, a New Zealand octopus that escaped an aquarium via a drainage tube that led back to the sea. It was actually used as the basis for Hank's escape in Finding Dory.

"Increasingly, researchers who study octopuses are convinced that these boneless, alien animals—creatures whose ancestors diverged from the lineage that would lead to ours roughly 500 to 700 million years ago—have developed intelligence, emotions, and individual personalities," writes Sy Montgomery in an article in Orion Magazine.

Although not as cute and furry as a labrador, an octopus also likes to play which is another sign of intelligence according to The Journal of Comparative Psychology.

Myth: Lizards are loners

Lizards may appear as loners with not much going through their lizard brain except for when their next fly meal may come along. According to Wired Magazine, these reptiles were assumed to be asocial and behaviorally simple. It seems lizards may be the misunderstood step-child of the reptile world. Recent research has shown some lizards are devoted parents, and mates that can distinguish their kin from strangers; they can even recognize individuals. Many lizards spend the first few months of their lives in the company of their siblings or a family group, where they might learn important life lessons and skills. And it can be detrimental to their development when they don't have social interactions, according to researchers from the University of Sydney. It seems that reptiles, like humans, benefit from an early environment rich in social interaction. (Need more socializing? Try some new ways to make friends.)

Myth: Blind as a bat

That saying may be appropriate when your son can't find the ketchup bottle right in front of his face or your husband lost his car keys... again. (Share some tips with them on getting organized.) But it wouldn't be fair to cast aspersions bats.

Yes, says Livescience, bats hunt in the dark using echolocation, which means they use echoes of self-produced sounds bouncing off objects to help them navigate. But they can also see. Research indicates that bats sometimes prefer using eyesight to sound when hunting. And many fruit bats don't even echolocate at all. In fact, they have particularly sharp vision.
