A lot of tests of bite force have been conducted from the safety of a desk If you ever see a blue whale, keep your distance — for its safety and yours. Their growth rate is likely one of the fastest in the animal world, with a several billion-fold increase in tissue in the 18 months from conception to weaning. While they have a cruising speed of 5 mph (8 kph), they can accelerate up to 20 mph (32 kph) when needed. Blue Whales Can Grow More Than 100 Feet Long, 2. They Can Weigh as Much as 30 Elephants. One example of a killer-whale culture, he said, is the teaching of a particularly difficult and dangerous hunting technique observed by researchers on Antarctic islands. good, good job. Apart from any fair dealing for the purpose of private study or research, no This is just speculation but I think hammerheads and 7 gill sharks would make up a substantial part of the cs and gs diets. Killer whales are on average a bit heavier than elephants—about seven tons versus an elephant’s six. Equally remarkable to researchers is the orca's ability to communicate with whistles and pulsed calls, and to "see" by making a clicking sound that works like sonar. Their language of pulses, groans, and moans can be heard by others up to 1,000 miles (1,600 kilometers) away. Boat collisions can seriously injure blue whales. The three groups have starkly different diets, languages, hunting techniques and manners of behaving around other marine life, and they don't seem to interact much with one another. Give or take. But in years where the orcas make an appearance, which they did … "I'm not trying to second-guess what was in this particular whale's mind," said Marino, part of the Neuroscience and Behavioral Biology Program at Emory University in Atlanta. The blue whale's heart is huge. But orcas learn local and complex languages that are retained for many generations. Adult elephants eat about 300 pounds of food a day. Species ID Suggestions Sign in to suggest organism ID. Similarly, the orca would be in alot more trouble if the cs attacked it than if it attacked the cs or new the cs was coming. She is a sustainability expert and author whose work has been published by the New York Times and National Geographic, among others. Instead of the world's varied populations having genetics that spread outward like a tree with several main branches, theirs is but a single, nearly straight trunk, except for a mismatched pair of genes here and there. The planet is covered with amazing, fascinating creatures, but the blue whale is in a league of its own. Blue whale calves are the biggest babies on Earth, easily, and at birth already rank among the largest full-grown animals. Both the great white shark and the killer whale or orca are fearsome top predators. A blue whale’s tongue alone can weigh as much as some elephants. These researchers have yet to find evidence that an orca in the wild has ever killed a person. Get weekly and/or daily updates delivered to your inbox.

From 1904 to 1967, more than 350,000 blue whales were killed in the Southern Hemisphere, according to the World Wildlife Fund. Researchers find Mars has a Chandler wobble, Evidence of huntsman spider creating leaf trap for a frog found in Madagascar, Self‐folding 3-D photosensitive graphene architectures, Eight binary millisecond pulsars examined by researchers, Experiments with bifluoride ions show evidence of hybrid bonds. But they aren't surprised that the world's biggest, most powerful and possibly smartest predator, captured and kept for years in a tank, cut off from the influences of an extended family, could have a fatal encounter with a human. Why Did This Blue Whale Swim Into the Red Sea? ... Decision in Killer Whale vs Great White Shark: Orca Wins!

Sam Ridgway, a neurobiologist and research veterinarian at San Diego's National Marine Mammal Foundation, which works for the Navy, said the orca brain has a relatively smaller amount of cerebral cortex -- the gray matter involved in memory, attention and thought -- than the human brain does. The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales (called Mysticeti). There is one population of around 2,000 blue whales off the coast of California, but all told there are only around 10,000 to 25,000 individuals left. Blue whales, in fact, are the loudest animals on the planet.

But, if you put an orca in an olympic pool with mud in it and the battle started in a shallow end, and put the elephant in, and if you sizes are the upper range for each male, which is 13,200 lbs each, then the advantage would be to the orca because the orca has more of it's mass concentrated as muscle, because a sea mammal. "They are able to use their bio-sonar to detect and track and eventually catch them.". Click here to sign in with For comparison, an adult African bush elephant weighs up to 6 tons, so it may take 30 or more elephants to equal the weight of one blue whale. Marino, the Emory neuroscientist, wonders about the extent to which a captive orca could grow frustrated with being cut off from the cultural richness of living among an extended family -- grandparents through calves -- and the environmental richness of swimming the world's oceans. "But, certainly, if we are talking about whether killer whales have the wherewithal and the cognitive capacity to intentionally strike out at someone, or to be angry, or to really know what they are doing, I would have to say the answer is yes.". Before whalers discovered the treasure trove of oil that a blue whale could provide, the species was plentiful.

Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. "They have their way of doing things, which they've learned from their mother and their other relatives," Whitehead said.

Blue Whale is dominant over all the sea animals due to its massive size and hunting ability, and it would be quite difficult for other animals to defeat it. Two of the largest creatures on Earth do battle with words and rhyme. But scientists use brain-weight-to-body-weight ratios as a rough measure of intelligence. Blue whales won't eat elephants! 1. Hal Whitehead, a biology professor at Dalhousie University in Nova Scotia, awakened the world of cetacean research in 2001 when he co-authored a controversial paper that suggested no species other than humans are as "cultural" as orcas. While not nearly as old as the Earth’s oldest trees, blue whales are among the planet’s longest-lived animals. Picture in your mind a 10-story-tall animal walking down the street and you probably start channeling images of Godzilla or King Kong. "A cultural species starts behaving differently than a species where everything is determined genetically.". Bigger animals typically have bigger masses of brain cells. Orca vs Killer whale It should be a well understood fact that there is no pronounced biological difference between orca and killer whale, but the two names are different in their origins. An unlikely background character, the elephant seals! Elephantsare one of the largest mammals on Earth, they are members of the family Elephantidae and the order Proboscidea.

"Living in a tank and having to splash people with your tail every day for 27 years would make anyone go nuts," Marino said. "The bigger the axon, the faster the nerve impulses travel.". Medical research advances and health news, The latest engineering, electronics and technology advances, The most comprehensive sci-tech news coverage on the web.
