The facts about dolphins will be quite interesting and amazing as we all know they are close to humans in their communication skills and social behavior. Let’s get some basic information about dolphins and their characters.
What are Dolphins?
Dolphin is an aquatic mammal. They are highly intelligent mammals that can live in water but breathe through the lungs just like we do. They don’t have gills like fishes. Dolphins have blowholes known as their nostrils present on the top of their heads.
Family Of Dolphins
Dolphins belong to the phylum Chordata with infraorder Cetacea. All the oceanic mammals belong to Cetacea. Their whole life cycle and lifestyle depends upon water.
Appearances Of Dolphins
Talking about their body mass, Dolphins are usually 1.7 meters long and 50 kgs in weight. Male dolphins are, in general, sizable than females. Their body is streamlined shape with two flippers. Unlike seals, dolphins are less flexible.
Habitats of Dolphins
Dolphins are present in the sea as they are oceanic. However, dolphins can reside in some rivers. Some dolphins like to live and spend their lives near coastal areas. Whereas some species of dolphins like shallow water located further out to sea.
Species Of Dolphins
There are altogether 42 species of dolphins all around the world. The killer whale is known as the largest dolphin in the world. Hectors’ dolphins and Franciscans are the smallest ones.
Facts About Dolphins
As we know dolphins are very friendly with humans, let’s try to find out some amazing facts about dolphins that we do not know. “Dolphins are social mammals” and why is discussed below in the list of some facts about dolphins.
1. They are Available in Different Kind of Environments
Various species of dolphins have been scattered all around the world in divergent types of environments. According to the species of dolphins, they choose their surroundings. Altogether thirty-six species of dolphins live in marine water including, coastal, oceans, estuarine, and freshwater.
They are present in temperatures less than 0 degrees to more than 30 degrees Celsius. Bottlenose dolphins are widely present around west wales and the eastern Scotland of Britain. Scotland is home to most bottlenose dolphins and, they love to spend their life in Scotland.
On the other hand, the Amazon River is home to four species of Dolphins. Boto or pink river dolphins love to reside in the Amazon River.
2. They are Social Mammals
Dolphins live in pods of up to dozens of other individuals. They are highly social mammals, unlike other marine animals. They communicate with the help of squeaks, clicks, and whistles.
Each dolphin has its unique vocal pitch. Having different vocal tones is necessary as they move with the pods and, dolphins should know and identify who is speaking or communicating.
They are active and love to stay with their families. The group of dolphins is known as pods. They are empathetic, social with the same species as well as with different species. Dolphins can work with humans as well. They show cooperative and altruistic behavior.
3. They Nurse Their Young Ones With Care
Dolphins are warm-blooded animals and, they care for their babies as other mammals do. Mother dolphin gives birth to only a single baby at a time. They can give birth to babies every 1 t 6 years, depending upon the species of dolphins. Female dolphins have more than one mate.
Dolphins get pregnant for 12 months according, to the research of bottlenose dolphins. They have little room in the uterus for their baby to fully develop. Dolphins give easy natural birth to their babies. Their tail fluke and dorsal are cartilaginous and have a fold-over uterus.
4. Risks to Dolphins
According to the research, underwater noise pollution is one of the biggest threats to dolphins. There is an increment of marine traffic throughout the oceans around the world. Noise pollution from the naval activity, gas and oil industry, seismic surveys, and underwater constructions can injure and stress dolphins and all the cetaceans.
The situation can severely affect the communicating, reproducing, navigating, and finding prey capability of dolphins. The circumstances can be fatal in the future. Another threat can be human beings.
Most human beings have haunted dolphins for their meat and their fats. They can get caught in fishing nets or traps. When dolphins get entangled in the net, they may face serious injuries. Let’s not be ignorant and accept one of these facts about dolphins that we are the ones responsible for destroying their habitat.
5. They are Fast
Dolphins are also known as fast sprinters. Dolphins are fast because of their tails. They can travel about two mph whereas, sometimes, they can reach speeds over 30mph. Killer whales, the largest dolphin, can travel 56 km/hr.
Dolphin’s tails are capable enough to thrust the speed the mammal through the water. Their tails or flukes are highly flexible than their body, which enables dolphins to maintain the highly efficient way of swimming overboard range of speed.
6. Dolphins Blow Their Bubbles
Most of the cetaceans like dolphins, humpback whales, beluga whales blow their bubbles. They blow their bubbles to herd their prey to the surface during hunting. They use some hunting techniques like “fish-whacking,” using their tail to hit the fish and hunt them.
Sometimes, dolphins blow their bubbles as a part of sexual behavior. They also sometimes blow bubble rings. They make bubble rings with the help of their tail using the reservoir of the air.
7. They Are Chatty Mammals
As mentioned above, dolphins use squawks, squeaks, clicks, whistles, and moan sounds while communicating. They can represent the acoustic activity to the animal kingdom. While speaking or chatting, the dolphin’s body becomes leaner. Compared to porpoises, dolphins are more talkative.
They usually make whistling sounds from their blowholes to talk to other individuals underwater. They can make sounds anytime also they make different voices in different depth of the water. Their tone may vary accordingly in volume, wavelength, pattern, and frequency. They also use their signature calls or whistles to introduce themselves to others.
8. They are Intelligent
Dolphins are as smart as we human beings. They have superior problem-solving skills and social skills. Bottlenose dolphins are known as those species like humans and apes that can recognize themselves in the mirror.
It is known as reflective intelligence. Dolphins have also documented using tools like other intelligent animals. Studies have shown that dolphins are good learners. They can pass their knowledge to others.
They have high brainpower than other animals. They can related and empathize with others and know how others are feeling. At one scale of brain function, dolphins can beat humans. Orca intelligence is extensively present in bottleneck dolphins.
These are some amazing facts about dolphins that may give you an insight into the mammal’s lifestyle and behavior. These are the reasons why dolphins are one of the most brilliant and expressive marine species.
