People seldom see squid jump out of the sea. Some researchers think that this kind of travel is rare in migration, but there is some evidence that this kind of behavior may be more common than people think. Julia Stewart, a marine biologist at the Hubble Space Experiment Station of Stanford University, tracked the Humboldt squid. He recently found that these squid migrate much faster than before.
On February 20th, Stewart presented his research results at the Marine Science and Technology Conference organized by the American Geophysical Union in Salt Lake City. Addo, Stewart and other researchers analyzed a set of photos taken by photography enthusiast hoels in Brazil in 2009 (see here for the oversize picture). This set of photos is thought to be pterodactyl jumping out of the water. This squid does not touch the wrist and feet, and it is about 6 cm long.
According to the photo data, the researchers calculated that the speed of squid flying when spraying water is about five times faster than that of similar swimming. Addo said that this may indicate that these squid can save energy by "flying". Some squid species spend a lot of energy on migration every year, and some squid will migrate 1000 kilometers to lay eggs. Addo said that even if there is evidence that females will eat males, it cannot explain how they get so much energy.
