Do Dolphins Have Eyelashes? (Protect Their Eyes)

Dolphins are easy to claim as everyone’s favorite mammal in the seas. It would come as no surprise since they are known to be very calm and friendly to humans.

They also have certain behaviors that make them very relatable. Aside from their natural behaviors, everyone may be curious about what other similarities we have to them like, do dolphins have eyelashes?

Do dolphins have eyelashes? Although they are born with a small number of hairs around the beak, at no point do dolphins have eyelashes. Eyelashes are useful for protecting the eyes from small particles like dust or debris, which are less common risks for dolphins in the water.

Do Dolphins Have Eyelids?

All mammals including dolphins have eyelids that help to protect the eyes from dangerous objects and debris. The eyelids of a dolphin have tear glands that create a protective solution that spreads over the entire eye through blinking. Since dolphins don’t frequently blink, the solution can protect a dolphin’s eyes for several hours at a time.

Their eyelids are fatty and heavy compared to a human and can be much harder to move. This is one reason that dolphins and other mammals blink less often than humans and other animals.

Similarities Between Dolphins and Humans

Even though they have no eyelashes, there are plenty of other similarities between us and dolphins. They may not appear like anything near to being human and, yet, they are obviously very much like us inside. This puts so much value on the efforts of taking care of these creatures as much as there is much value in human life.

They knit tightly with their families – This is very similar behavior to all other mammals on land where they easily identify with their kind. Even if many would contest that this is also the case for all other animals, the connection among dolphins is surely tighter.

They do not lay eggs, instead, births are delivered live – Just like any other human, they give live births. Even though they live at sea, they reproduce nothing like fish in eggs. Instead, dolphins give birth to a new dolphin who swims as well as its mother.

Dolphins communicate with a specific language – They can relate to one another by creating a specific type of sound, similar to how humans communicate with each other. The sounds they create are exclusive to them and these sounds are found to have a specific wave that only they can understand.

These creatures have genes and brains that are almost like all other mammals in terms of structure – Dolphins are easily validated as mammals because of their brains and genes. It appears from many studies that theirs are just like other earth-walking creatures.

Dolphins have bone fragments that are almost like humans – Their flippers may appear like that of a fish. On the other hand, these have so many similarities to those of human feet and hands that make them undeniably mammals.

Differences Between Dolphins and Humans

The similarities and differences between humans and dolphins make them both relatable. Yet, one cannot help but respect their uniqueness because it is what truly makes them stand out in the animal kingdom.

Cannot show facial expressions – Dolphins mainly rely on sounds and body language to communicate with others, while we portray a lot of feelings from facial expressions.

Never fully fall asleep – Because of the dangers of the water and to stay safe from active predators, a dolphin’s brain never enters a deep sleep. They keep half of their brain active while sleeping which lets them stay alert and keeps them from drowning.

The hair on bodies – Besides the few hairs when they are born, dolphins have no other hair on their bodies. That’s completely different than humans who have hair all over the body and the reason is that the function of hair is less useful for dolphins.


Dolphins are born with eyelids to help them see and to stop debris from getting in their eyes but don’t have eyelashes as they serve no practical point for protection. In general, there is a small number of hairs that are found on dolphins immediately after birth, but it doesn’t remain for very long.
