Something in the ocean changes the shape and color of the body during the attack: scientists have shot it on video
An attempt to catch food in an animal world is usually associated with a number of problems: first you should find prey, then catch it and try not to fail that attempt to lose your lunch. In a new study, scientists focused on learning more about cuttlefish and hunting. In focus. Technology has appeared its Telegram channel.

During the study, scientists near the CRI Islands and Mansuar in the east of Indonesia were harassed with cuttlefish in the form of living crabs, and then watched her approach - the animal's behavior was recorded on the GPPRO camera. In total, scientists have removed 234 demonstrations and found that cuttlefish used four basic hunting behavior, which scientists called: According to the author of the study, Dr.
Matteo Santon, they with their colleagues found that cuttlefish are incredibly cleverly manipulating their appearance, including color and body texture. For example, a wide -haired cuttlefish (Sepia latimanus) usually either catches its prey with two longer hands, or uses all four pairs of hands to get it into a trap. Interestingly, the approach to this stage of the animal usually use one of four strategies.
During the attack, the side limbs of the cuttlefish are extended to the sides, and its skin has an olive green or white color. The animal is also slowly approaching its prey. During the passing attack, the body position looks like a sheet, but cuttlefish can draw a black strip along your body and get closer to the prey straight.
When the branched coral is attacked, two central pairs of hands are raised, and the lateral pair of hands is pulled dorso-lateral, sometimes kept smooth or with regular bends on the hands; In this case, the color of the cuttlefish remains the same at attack, but has a pale or dark color with dark spots. In the demonstration of the pulse, two lateral hands rise together, forming a cone, while two central hands go under water; Body color is gray with dark spots.
Interestingly, cuttlefish also mixed their demonstrations, switching from one form to another while approaching prey. Scientists suggest that these demonstrations are probably useful not only for hunting, but also help to hide from predators effectively. At the same time, males and females used all four demonstrations, except for the demonstration of leaves, which females used 13% more often.
