Type D whale may be a new species of killer whale. J.P. Sylvester killer whales are beautiful and majestic, but their looks have hardly changed-from whales to whales, their shapes, sizes and colors are quite standard. Therefore, when people began to find that killer whales were obviously different in appearance, scientists noticed that they were thinner, with smaller white eyes and narrower and sharper dorsal fins. An international research team tracked down these potential killer whale swindlers and collected samples for genetic testing to reveal whether these animals are newly discovered unique killer whale species.

"We are very excited about the upcoming genetic analysis," Bob Pitman, a researcher at the Southwest Fisheries Science Center of the National Oceanic and Atmospheric Administration, said in a statement. The killer whale type D may be the largest unrecorded animal on earth, which clearly shows our understanding of marine life. The existence of this newly discovered species is only based on the story of fishermen and a few photos. "KDSP" and "KDSP" are the first records of these mysterious whales. Animals dating back to 1955 and 17 ran aground on the coast of New Zealand. Although their markings are similar to those of known killer whales, these animals are smaller, with blunt noses and spherical heads. Compared with typical killer whales, stranded whales have narrower and sharper dorsal fins and smaller white spots above their eyes. Experts speculate that this unusual whale is only the product of genetic variation, and only those individuals exist. Then, in 2005, a French scientist showed some strange-looking photos of killer whales, which were fishing in the Croze Islands in the South Indian Ocean. These whales look exactly like those stranded in New Zealand 5,500 miles (9,000 kilometers) away. This shows that this unique whale is more widespread than previously thought.

It is a typical adult male whale. Pay attention to the size of the white spot, and the shape of the head and dorsal fin is not round. At the bottom is a picture of an adult male killer whale type D. Note its small eye patch, rounder head and narrower and sharper dorsal fin. In the next few years, Pitman and his colleagues collected thousands of photos of tourists and ships from the Southern Ocean. By 20 10, Pitman and his team had collected six photos of killer whales, which they called "type D" killer whales. These photos of type D whales were taken under the worst rowing conditions on earth. These areas are called the roaring 1940s and the raging 1950s because of the sinister winds in this area. If type D whales like to haunt these places, it is no wonder that humans have not noticed these whales until recently.

This is the last piece of the puzzle. After years of collecting information about potential unknown killer whales, Pitman ventured out to sea to find this mysterious creature. He recruited an international team of marine mammal experts to accompany him. On June 20 19, the research team left the coast of Argentina and found a nest of about 30 D whales.

The research team spent about three hours with whales and recorded the sights and sounds they encountered on the surface and underwater. The researchers also collected three slices, or a small piece of skin, from these whales, and these slices will be genetically tested to reveal how close the D whale is to the typical killer whale. Pitman and his team said that the discovery of killer whales type D reminded us how much we still need to know about marine life.
