National Dolphin Day takes place Friday, April 14, 2017!
Here are five fun facts about bottlenose dolphins:
Dolphins are marine mammals, which means they must come to the surface of the water to breathe. They can hold their breath for up to 7 minutes!
Dolphins can exhale air at 160 km/hr (100 mph) through their blowholes.
Dolphins never fully sleep. One side of their brain must always be active so that they remember to breathe. (They are not involuntary breathers like humans. They must consciously swim to the surface to take a breath.)
Dolphins have a nearly 360-degree field of vision, and they can move one eye independently of the other.
Dolphins produce high-frequency clicks that humans can’t hear. They use these clicks in a sonar system called echolocation. When the clicking sound reaches an object, it bounces back to the dolphin as an echo. Dolphins can process this information to determine the shape, size, speed, distance, and location of the object.
A dolphin calf was born Tuesday at 9:36am at SeaWorld Orlando. The calf weighs 35 pounds and is 40 inches long, with the sex unknown at this time. It was seen nursing and bonding with its mom, both a good indication that the calf is doing well. Park guests can see the pair at SeaWorld’s Dolphin Nursery. In the nursery pregnant dolphins, new mothers, their calves and experienced moms live together.
Imagine seeing up to 1000 dolphins swimming together – would it frighten you or make you stare in awe? Such a sight was recently seen by wildlife spotters off the coast of Skye in Scotland. The pod of short-beaked common dolphins are thought to have grouped together to chase a shoal of fish.
In this fascinating special hosted by David Attenborough, the ability of dolphins to think creatively and abstractly is explored. The video provides a unique look into the depth of dolphins’ intelligence.
Back in September of last year, we posted a video of dolphins making air bubble rings with their blow holes. Now, SeaWorld curators in Orlando, FL have noticed a surge in this playful activity in their dolphins at Dolphin Cove. The dolphins create a perfect bubble ring and then push it with their rostrums (bottlenoses) or bite it. The dolphins learn the technique by watching other dolphins create rings.
Snopes.com has recently verified the phenomenon of dolphin bubble rings. This video shows dolphins creating these bubble rings, which are essentially water vortices infused with air, and then playfully biting them or swimming through them.
