Our world is full of animals from small insects to gigantic fish. The speciality of these animals is from a creation from nature which enhances their instincts for survival. Sometimes, the advanced habits or appearance of animals can unexpectedly surprise us. Today, ACU PAY will take you to take a look at animals’ fun facts that many people may not know. Let’s see what fun facts that are waiting to be read!

1. Dogs have the third eyelids

If you take a look closely, dogs have the third eyelids which are similar to reptiles at the corners of their eyes. The third eyelid of dogs is called the Nictitating membrane which is a thin tissue layer between the eyelid and the cornea. There’s a T-shaped cartilage the same as humans which is the pink and white tissue right at the corner of our eyes. The role of the third eyelid is to generate tears and wipe off dirt. 

The disease about the third eyelid that can occur to dogs is called Cherry Eye. This is a disease caused by the gland of the third eyelid protruding abnormally. This causes the gland to expand and swell abnormally, causing the dogs to irritate until it can cause wounds. The only way to treat this disease is to undergo an operation

2. Cats can taste the air

We may have seen cats’ funny faces when they curl up their lips and show their cute teeth after they sniff something. This habit is called Flehmen response which is the sniff by using their second nose which is at the back of their fangs.  

Cats will open their mouth and taste the air, then convert those smells in the form of chemicals to nerve signals and send to their brains. This special organ is called the Jacobsen organ.

This excellent smelling skill makes cats know the changes in the weather such as the smell of ozone gas caused by distant lightning which lets them know that it is going to rain soon.

3. Pandas do handstands while peeing

การฉี่สร้างอาณาเขตอาจเป็นเรื่องปกติสำหรับสัตว์ทั่วไป ไม่ว่าจะเป็น น้องหมา น้องแมว รวมถึงสัตว์ป่าอย่างแพนด้า ก็มีการทำแบบนี้เช่นกัน 

แต่การจะสร้างอาณาเขตทั้งที การสเปรย์ฉี่อาจจะดูธรรมดาไป ซึ่งบางครั้งแพนด้าก็มักจะทำสัญลักษณ์กลิ่นของตัวเองไว้ ด้วยการเอาเท้าหลังสองข้างไต่ขึ้นไปบนต้นไม้ จากนั้นพวกมันก็จะทรงตัวด้วยเท้าหน้าสองข้างยันพื้นไว้ แล้วปล่อยฉี่ของตัวเองไว้ที่ต้นไม้นั้น ๆ ยิ่งถ้าสูงมากเท่าไหร่ละก็ จะยิ่งเป็นผู้ชนะมากเท่านั้นเลย 

4. Bengal tigers’ pee smell like butter popcorns

If you go in the woods and smell something like the smell of popcorn, this may not mean that there are people making popcorn while they’re camping but it can be the smell of Bengal tigers that used to pee to show their territory. The best thing you should do is to go the opposite way of the smell. 

Another tip for you if you unexpectedly encounter a Bengal tiger, the best thing to do is looking straight into its eyes and slowly walk backward. Do not run or turn your back on it.

5. Penguin can shoot 💩 bombs

Although penguins are cute animals with their adorable walking gestures, the routine of a penguin, apart from eating, is pooping. It can poop every 20 minutes and poop 6-8 times per hour because penguins have a fast metabolism.

Moreover, penguins do not poop in a normal way because they can shoot their poop bomb at 5 miles per hour. 

In addition, penguins’ poop causes nitrous gas or laughing gas in a high amount if the area is surrounded by a large group of penguins. The danger of the gas released by penguins has also caused one of the research teams who were studying Emperor penguins to go crazy and laugh without any cause because they were smelling a lot of laughing gas, some people have a terrible headache.

6. Whales’ age can be told by earwax

Who knows that the age of “Whales”, a gigantic mammals living in the ocean, can be told by the whales’ earwax. Naturally, the whales’ earwax benefits in transmitting sound waves underwater and blocks the inner ears. The length is 50 meters and can weigh up to 2 pounds. 

Marine biologists use whale’s ear wax which is  rich in DNA and important hormones to forecast the age, the same manner as annual rings in trees. If the color of whales’ earwax is soft, it relates to the period of searching for food. If the color of whales’ earwax is dark, it is during the migration. 

One unofficial printed study by Baylor University said they studied more than 20 pieces of whale earwax which is divided into 1,100 layers, found traces of Cortisol hormones, a stress hormone. This allows the study team to know how the environment that the whales live in makes them stressful, being hunted affects its behavior negatively, including what marks are left on their bodies.

7. Polar bears have black skin!

It may sound unbelievable, but polar bears actually have black skin. It can be noticed from their nose covered with hairs as white as snow. In fact, polar bears’ hair is a clear color. What makes polar bears’ hair look white is the reflection of light, ice, and white snow.  

The main function of black skin is to absorb the heat. The thickness of polar bears’ fat layer is 7-10 centimeters. That’s why the polar bear needs to store warmth for a long time. The reason why we see polar bears’ hair a little yellowish is because it is a fat stain from eating other animals such as seals.
