Do Dolphins Have Eyelashes?

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 mammal 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. In this article, I will answer the question and show you 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?

Dolphins are known to be similar to humans in several ways. Apart from not having eyelashes like humans, their kindness and calmness exert the intrinsic attributes of man. Humans treasure dolphins a lot, and some even take them in as pets.

Some of the similarities between humans and dolphins include:

a)       They give birth to their children alive – they don’t lay eggs:

Just like humans, they give birth to their children alive. Even though they are sea mammals, they don’t lay eggs like fish. They give birth to their young ones, who are taught to swim, just like human kids are taught to walk.

b)      They exert communal living

just like humans, dolphins exert these strong bonds among themselves. They live together and swim together. You can hardly see a dolphin only.

c)       Dolphins have a specific language

Just like humans, Dolphins communicate with each other using a particular language. However, the language is exclusive and only understood by them. This is how humans have a specific language no other species can understand.

d)      Like other mammals, Dolphins have bone fragments

Although they may have flippers like fish, their feet and hands are similar to humans.

e)       Like other mammals, Dolphins have genes and brains that are almost like that of humans in terms of structure  

Dolphins, just like other mammals, have brains and genes that validate them, even though they are sea creatures.

 

 

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 hairs, including having eyelashes. Also because body hairs are less helpful to dolphins.

b)      Cannot exert facial expressions

Unlike humans who can communicate and express emotions through facial expressions, Dolphins only depend on sounds and body movement to communicate.

c)       They sleep with half of their brain alert

Dolphins never fall deep into sleep; they always keep one part of their brain active. This is because they live in the sea, and they have to be always alerted of predators. Also, it prevents them from drowning.

What Other Animals Do Not Have Eyelashes?

All mammals, including pigs, cats, and dogs, have eyelashes. Animals like reptiles, aquatic animals, amphibians, insects, arachnids, and other non-mammals do not have eyelashes. On the other hand, Bird has a feather-like feature called bristles in a row-like structure that protects their eyelids.
