Do Dolphins Have Eyelashes?

I watched a documentary on dolphins, and a question kept coming to mind; do dolphins have eyelashes? Dolphins are the sweetest and most friendly sea mammals to man. It is no surprise for you to ask if dolphins have eyelashes due to their likeness to humans, but do dolphins have eyelashes?

I conducted my research, and I got answers to my question. I will answer the question in this article and show fun facts about dolphins.

Do Dolphins Have Eyelashes? 

No, Dolphins don’t have eyelashes, and they are known to be hairless. Only at birth can you see a small number of hairs around the beak. When they grow, it falls out, and they remain hairless. However, Dolphins have eyelids as they close their eyes while sleeping.

Do Dolphins Have Eyelids?

All mammals, including whales and dolphins, have eyelids that protect them from dangerous sea objects and debris, apart from losing their eye to sleep. The eyelids of a dolphin have tear glands that serve as a protective solution that spreads over the entire eye while blinking. As such, dolphins don’t constantly blink, the solution produced by the tear glands can protect the Dolphin’s eyes for long hours.

Like humans, Dolphin’s eyelids are heavy and fatty and can be harder to move. This is one reason mammals, including dolphins, blink less frequently than humans and other humans.

What are the Similarities Between Dolphins and Humans?

What are the Differences Between Dolphins and Humans?

Even though they are both mammals, differences make them unique in their way. Dolphins are particular because of their peculiarities that make them different from humans and other mammals, and some of the differences include:

a)       Dolphins are totally hairless

Apart from not having eyelashes, dolphins are hairless. They only have small quantities of hair when they are born, after which it falls out as they grow. While in the case of humans, a large part of the body is covered with hair, including eyelashes. Also, body hairs are less helpful to dolphins.
