Dolphins are regarded for being friendly creatures. There are around 40 different species of dolphins, with the bottlenose dolphin being the most frequent. Did you know these 12 Interesting facts about dolphins?
1. Dolphins Can Be Found All Over The World And In Different Environments
The most common species – the bottlenose dolphin – inhabits all regions of the planet, except for the “Antarctic and Arctic oceans“. This is one of the most interesting facts about dolphins.
Dolphins live in relatively shallow waters, but they can dive up to 900 feet.
2. They Stick With Their Mothers For A Long Time
It is in the nature of the dolphins to stick with their mothers for a long time before they leave their pack. Some stay with their mothers for 3 or even 8 years. This is also interesting facts about dolphins.
Dolphins are “equipped” with highly effective healing processes, which means that they don’t hemorrhage to Death easily
3. Under Water Noise Pollution Is A Real Threat To Bottlenose Dolphins
Marine traffic around the British Isles is amongst the most intense of anywhere in the world.
Noise pollution from naval activity, the oil and gas industry, seismic surveys and underwater construction can stress and injure cetaceans.
It also severely interferes with their ability to communicate, reproduce, navigate and find prey – sometimes proving fatal.
4. They’re Fast Sprinters
Bottlenose dolphins are usually fairly slow swimmers, travelling at about 2 mph. However they can reach speeds of over 30 mph for brief periods!
5. How Do They Eat A Fish? How Much Stomach Do They Have?
Probably not the same as a bottlenose dolphin, that’s for sure! They swallow a fish head first so the fish’s spines don’t catch in their throat.
Although dolphins have teeth, they swallow food without chewing it,
Dolphins don’t drink water because they get it from the food they eat.
They have 2 stomachs
One is used for storage of food and the other is used for digestion.
They’re piscivores, and eat around 35 pounds of fish every day, including squid and crustaceans.
6. They Like To Bubbles
When hunting dolphins produce bubbles to herd their prey to the surface.
They sometimes also use a hunting technique called ‘fish-whacking‘, where they use their tail to hit fish and so stun them – making them easier to catch.
7. Dolphins Are Chatty Animals
Dolphins have some of the most elaborate acoustic abilities in the animal kingdom.
Dolphins communicate through whistles, clicks, and other nonverbal forms of communication.
8. They’re Intelligent, Like Us
Bottlenose dolphins are one of the few species, along with apes and humans, that have the ability to recognise themselves in a mirror.
This is considered “reflective” of their intelligence.
Dolphins are also among the few animals that have been documented using tools.
Dolphins use their echolocation/sonar for navigating through the water and obstacles and hunting prey
Dolphins’ hearing system is so sophisticated and advanced that even a blind individual can survive
9. They Can Turn Off Half Of Their Brain
Bottlenose dolphins sleep with one half of their brain at a time, and “keep one eye open” .
It’s believed they do this to keep an eye out for their group – to make sure they stick together – and to look out for predators like sharks.
Dolphins sleep eight hours per day, and spend the rest of the day swimming.
10. When Do They Bite?
Dolphins only bite if they’re furious, angry, frustrated, anxious, or afraid.
11. From Where “DOLPHIN” Word Origin?
The name “Dolphin” comes from the Greek words “Delphis” and “Delphus,” meaning “Fish with a Womb”.
12. How They Are Used By Humans?
Dolphins are trained by “Military Forces” to Spot Mines and Find Lost Humans.
A group of dolphins is named a “School.” Female dolphins are “Cows,” Male dolphins are “Bulls,” and Juveniles are “Calves.”
