Baby dolphins, also known as calves, are fascinating marine creatures that capture the hearts of many with their playful demeanor and captivating appearances. These little ones are born in groups, referred to as pods, which serve as a support system that provides safety and guidance throughout their lives. It is within these groups that baby dolphins learn essential skills, such as socializing, hunting, and navigating their environment.

In the wild, baby dolphins face numerous challenges, especially when it comes to predators. By remaining close to their mothers and pod, they stand a better chance of survival and ultimately learning the ways of their aquatic home. This collaboration within the group helps these young ones grow into strong, intelligent animals capable of overcoming the obstacles in their aquatic habitat.

1: Baby Dolphins Use Their Tongues as Straws

Picture trying to sip a drink while submerged underwater – sounds impossible, right? This is the exact challenge baby dolphins face when nursing from their mothers. So, how do these little ones manage to drink their mother’s milk while underwater?

Surprisingly, baby dolphins use their tongues as a straw! When it’s time for the calf to drink milk, they cleverly roll their tongues up like a straw to latch onto the mother’s nipple. The mother dolphin then takes control of the nursing process, squirting milk right into the calf’s mouth. This efficient method allows a full feeding to be completed in just a few seconds.

To make nursing easier for the calves, dolphin breastmilk has a thick consistency, almost like a milkshake. This helps baby dolphins swim and suckle at the same time, making sure they get the nutrients they need.

Their unique method of nursing, combined with the ability to use their tail flukes for swimming and the amazing functionality of mammary slits, make baby dolphins remarkably adapted for life underwater!

A Dolphin Calf Mimics its Trainer by Creating Milk Rings Underwater

Dolphins are known for their intelligence, and baby dolphins are no exception. A six-month-old dolphin calf named Dolly displayed her intelligence by imitating her trainer’s smoke rings in the water. Upon observing the trainer blowing a cloud of smoke, little Dolly swam back to her mother and collected a mouthful of breastmilk. She then swam back and released the milk, forming a smoke-like appearance in the water[^1^].

Interestingly, her trainer did not teach Dolly this trick. She independently made the connection between releasing milk underwater and the similarity to smoke rings in the air. This example highlights the remarkable intelligence of dolphin calves[^2^].

3. Dolphin Calves Have Whiskers at Birth

Baby dolphins, especially bottlenose dolphins, are born with tiny whiskers around their snouts. These whiskers serve a crucial purpose for the newborn sea mammals, as they possess limited vision right after birth.

These wispy hairs allow them to:

  • Easily locate their mothers during their initial days.
  • Enhance their sensory perception before their eyesight develops.

Generally, within a few days, the whiskers on a female dolphin’s calf shed as they become unnecessary for the growing dolphin.

Baby Dolphins Are Unable to Breathe Underwater

It’s important to note that, unlike fish, baby dolphins are mammals and cannot breathe underwater. Dolphin calves, as well as adult dolphins, lack gills, which renders them incapable of extracting oxygen from water. Instead, they need to surface to breathe.

To ensure the calves don’t drown during birth, they are born tail first. This allows them to quickly surface for their first gulp of air. Dolphin calves can hold their breath for up to 15 minutes, using their lung capacity efficiently to maintain a steady oxygen supply to their brains.

But how do baby dolphins breathe? They don’t use their mouths like other mammals. Instead, they rely on blowholes located on the tops of their heads. Each breath a dolphin calf takes fills approximately 80% to 90% of their lungs. This is an impressive feat when compared to humans, who typically fill only 10% of their lungs with each breath. This unique adaptation showcases the amazing abilities of baby dolphins.

5: Dolphin Calves Master Swimming Before Birth

Dolphin calves are well-prepared for their aquatic life even before their birth. In an extraordinary process, they start learning swimming skills during their gestation period.

As early as 9 weeks into the gestation, which usually lasts between nine to twelve months, researchers have noticed that baby dolphins begin to swim inside their mother’s womb. This extensive practice time ensures that newborn calves are ready to swiftly reach the water’s surface for their first breath upon birth.

Their remarkable ability to develop swimming skills pre-birth makes dolphins truly unique creatures of the ocean.

FAQs (Frequently Asked Questions)

  • Baby dolphin size: Newborn dolphin calves typically weigh between 22 and 44 pounds and have a length ranging from 39 to 53 inches.
  • Diet of baby dolphins: For the first six months to two years, baby dolphins rely solely on their mother’s milk. After this period, their diet consists of crustaceans and fish.
  • Terminology for baby dolphins: A single baby dolphin is referred to as a calf, while a group is called a pod.
