Dolphins could be described as man’s best friend in the waters. But how do they act when we’re not looking?

Dolphins typically like to hang out with humans, we all know that. They’re playful, friendly, and acrobatic when they spot friendly humans around them. But does their behavior change when we are not looking?

A team of scientists set out to find out that information.

Secret Life Of Dolphins: What Scientists Seek To Learn

Researchers fitted tiny cameras onto 8 wild dusky dolphins and were able to capture almost 10 hours of footage showing the marine mammals doing things humans had rarely witnessed before.

This research is the first of its kind and showed mothers of the species interacting with their calves, playing in kelp seaweed forests, and so on. Also, scientists witnessed some unusual displays of affection between pod members, specifically a habit of rubbing flippers.

The team was made up of researchers from the University of Sydney (the Charles Perkins Centre) and the University of Alaska Southeast.

Dr Gabriel Machovsky-Capuska from the University Of Sydney reports that they did not use invasive underwater housings or wildlife crews. And the dolphins were in no way affected by the cameras.

Cameras Used

The project deployed cameras loaded with memory boards, high frequency transmitters, and satellite transmitters. Each one had a battery designed to last for about 6 hours.

However, attaching the cameras on to the dolphins was quite challenging. For one thing, unlike other species like Orcas or even common bottlenose dolphins, dusky dolphins are relatively small. Also, they are fast, so getting close enough to them in a bobbing boat was tough.

In addition, their small size meant that there’s  limited surface on the animal’s body and just a small window of time to quickly deploy the tag as the dolphins swim past.

They were able to successfully attach the devices using suction cups, long poles, and Velcro pads. The project lasted between December 2015 and January 2016 and took place in the waters around New Zealand.

 “For the first time, these cameras have given us the opportunity to see what dolphins do on their own terms,” – Dr. Gabriel Machovsky-Capuska, School of Veterinary Science and Charles Perkins Centre, University of Sydney.

You can read more about the results as published in the Marine Biology Journal or watch a brief video extract from the footage below.

 

 

Plans To Capture Other Marine Species

The exercise was so revealing that the group hopes to repeat the procedure with other marine creatures like sharks for instance.

But what does all this seek to achieve?

  • Rather than being an avenue to just satisfy our curiosity about what these creatures do when we are not looking, there are some conservation benefits too. For example, getting a better idea about the kind of challenges the creatures face in their natural
  • In areas with a lot of human activity (like shipping routes, tourism, etc.), this kind of footage could pinpoint the impact on the dolphins.
  • Help to better comprehend the health and balance of marine environments including the dolphins’ prey that humans also fish. This includes different species of fish and squid that humans consume in large quantities.

Ultimately, collecting this data will help us better understand how our own activities impact marine creatures and their ability to feed, grow, mate, and raise their young.

Taiji, a southwestern coastal town of Japan got into the limelight after the award-winning documentary film, “The Cove,” brought the world’s attention to the brutalities facing dolphins there.

The small town is known for its supply of wild dolphins, especially bottlenose dolphins, to aquariums globally. Dolphins and whales are rounded up and slaughtered brutally for their

Animal rights activists are continuously alarmed over Russia’s killer whale trade.

Russia's Killer Whale Trade

Although many countries worldwide are gradually ending dolphin capture and entertainment due to the obviously negative effects of captivity on these creatures, countries like China aren’t. And Russia is supplying the required “goods” in large numbers.

In fact, Chinese dolphinariums and aquariums are expanding and drawing large crowds with Russian dolphins and whales on display. The most common large marine mammals in question

Our Killer Whale video roundup features real footage of the apex marine predators at their element.

Killer Whale Video 2017

Our Compilation Of Killer Whale Videos Will Keep You On The Edge Of Your Seat.

Killer Whales, or Orcas, are likely the most majestic, beautiful, yet frightening creatures out in the Earth’s waters today.

This is the ultimate apex predator and no other large sea creature is safe from it: Not even the Blue Whale!

Lucky for us, they don’t target humans as prey and can even be quite friendly out in the wild. So, we’ve searched for the most popular killer whale videos from recent years up till 2017 and

White Killer Whales were once the stuff of myths and legends but that’s no longer the case.

A little over 6 years ago, while working on a project in the western North Pacific whale researchers noticed a very unusual creature. It was a white male killer whale or orca whale.

They nicknamed this phenomenal dolphin “Iceberg” because of the way his white dorsal fin stuck out of the water.

But just a couple of days later they were in for another surprise: The same dolphin reappeared in a large pod of killer whales and there was another orca just like him!

You may wonder what’s so strange about that until you realize that this is a very rare creature

Illegal fishing activities in Myanmar’s waters are putting a dolphin species on the brink of extinction. Commonly called the “Smiling Dolphin,” the Irrawaddy Dolphin is surprisingly a close relative of the fearsome Killer Whale (Orca).

It’s called the “smiling” dolphin because of the curve of its mouth which gives it the appearance of a permanent, friendly smile.

The Irrawaddy dolphin is a marine mammal native to the waters around India and Northeastern

Dolphin Meat is flesh obtained from the body of a dolphin and in some parts of the world you can find it on display for sale in supermarkets and through meat distributors for human consumption.

The meat is dense and a very dark shade of red: So dark that it appears black. People who eat it may consume it raw or cooked usually garnished with onions and garlic. Others choose to cut it into bite-sized chunks and fry it or simmer it with sauce and vegetables. When cooked, those who

These are the largest dolphins today and they are all referred to as “whales.”

Melon-Headed Whale: Largest Dolphins

Dolphins remain one of the most popular marine creatures among humans and that’s understandable.

Their friendly disposition and interesting antics makes us want to watch them as much as possible. But did you know that there are a number of marine mammals that you may think are whales but they are actually dolphins?

It’s not hard to see why this mix-up happens all the time especially as each one has the word “whale” as part of its common name. Also, these whale/dolphins are the largest in the dolphin family.

After the true whales (blue whale, gray whale, etc), the dolphins below are the largest mammals you can find in the waters.

If you were to count the most popular whale watching locations worldwide, the UK would not come top of the list. But around the British Isles, several species of marine mammals do make an appearance yearly. Marine mammals like fin whales and porpoises will appear from time to time.

However, Scotland’s West Coast is the native habitat of a resident pod of killer whales: the only killer whales in the UK. Unfortunately, scientists expect that the small pod of just eight

The Wholphin is not a myth, it actually exists as these facts show.

In this world there exist some unique animals that pop up maybe once in many generations and one of them is the Wholphin.

This is a rare sea mammal that came into existence as a result of crossbreeding between a male False Killer Whale and female  Common Bottlenose Dolphin. Just as its name suggests, it is a product of the two marine mammals. Because of the big difference in size between false killer whales and bottlenose dolphins, many people are fascinated at how the two managed to mate.

The false killer whale scientifically is a member of the dolphin family. In fact, both these animals are members of the toothed whale suborder.

Although several people claim that they have seen  wholphins in the wild, this is an extremely
