Iguanas, Koalas and Komodo dragons all have two penises.
Iguanas, koalas, and Komodo dragons (along with many other reptiles and some mammals) have a unique reproductive feature: they possess two penises, or more accurately, hemipenes in the case of reptiles like iguanas and Komodo dragons. For koalas, they have a bifurcated (split) penis.
Dolphins sleep with both eyes open.
Dolphins do not sleep with both eyes open, but they do sleep with one eye open! This is because dolphins use a unique sleeping method called unihemispheric sleep, where only one half of their brain sleeps at a time while the other half stays awake. When a dolphin sleeps, the eye opposite the awake side of the brain stays open. This allows them to keep an eye out for predators, stay aware of their surroundings, and continue surfacing to breathe. After a while, the sides switch, so both halves of the brain get rest. This adaptation is crucial for their survival in the ocean!

Rat poison is so effective because rats can't vomit or burp.
Rats aren't the only animals that can't vomit. Other rodents, like mice and guinea pigs, also lack this ability. This trait is due to the structure of their digestive system and a strong barrier between the stomach and esophagus. Because of this, rats are very cautious about trying new foods—a behavior called neophobia. To overcome this, some rat poisons are designed to be slow-acting, so the rats don't associate the poison with the food they ate.

The European Wels catfish in France can lunge out of the water and hunt pigeons with a 28% success rate.
The European Wels catfish (Silurus glanis) in France has been observed exhibiting a unique and surprising behavior: lunging out of the water to catch pigeons on land. This behavior, known as "beaching," has been documented in the Tarn River, where the catfish have adapted to hunt birds. Studies have shown that these catfish have a success rate of around 28% when attempting to catch pigeons.
If you shave the striped fur off of a tiger, the skin underneath will be striped the same way.
If you were to shave the striped fur off a tiger, the skin underneath would indeed have the same striped pattern. The stripes are not just in the fur—they are part of the tiger's skin pigmentation. A tiger's stripes are like fingerprints—no two tigers have the exact same stripe pattern. These unique markings help tigers blend into their environment, especially in tall grass or forests, making them excellent ambush predators.
Humans are the only primates that can have blue eyes.
While blue eyes are rare in non-human primates, they do occur in some species. For example, certain blue-eyed lemurs, like the Sclater's lemur (also known as the blue-eyed black lemur), naturally have striking blue eyes. Additionally, some individual primates of other species, such as gorillas or macaques, can occasionally have blue eyes due to genetic mutations or albinism.
The placement of a donkey's eyes in its head enables it to see all four feet at all times.
Donkeys can see almost everything around them—almost 360 degrees! The only spots they can’t see are right in front of their noses and directly behind them. This helps them stay safe from predators. But because their eyes are on the sides, they’re not great at judging distances, which is why donkeys sometimes seem cautious or unsure when they’re checking out something new.

Anteaters only have teeth on the sides of their mouths shaped like flat stones to crush insects.
The anteater does not have any teeth. It does not require teeth to eat due to its large tongue that can extend over 2 feet (60 cm) away to gather insects to swallow whole. - allthingsnature.org/does-an-anteater-have-any-teeth.htm
Which animal has the most taste buds?
Catfish (order Siluriformes), those beady-eyed fish named for their feline-like whiskers, typically have more than 100,000 taste buds. Some large catfish can have as many as 175,000. - livescience.com/32970-what-animal-has-the-best-sense-of-taste.html
A crocodile can stick out it's tongue the same length as its tail.
Corcodiles CANNOT stick out their tongues. A crocodile's tongue doesn't move. It is held in place at the roof of the mouth by a membrane. Because crocodiles spend so much time underwater, the tongue helps keep the throat closed, protecting the animal's airway. - animals.mom.com/size-crocodiles-teeth-8551.html
All shrimp species are born male but some slowly grow into females as they mature.
Not all shrimp are born male and then change into females. However, some species of shrimp do exhibit protandric hermaphroditism, where they start life as males and later change into females as they mature. This is not true for all shrimp species, though—it depends on the specific type of shrimp.
