However, the largest carnivore in the strict sense in history is the sperm whale. It is a toothed whale that preys on squid, and sometimes it preys on another huge predator-giant squid.
There are some amazing videos on the Internet about the battle between sperm whales and giant squid. Of course, these are speculations, because sperm whales hunt in extremely deep places, and the whole battle is a bit mysterious. However, there is evidence that the battle is quite fierce considering the anatomical structure of squid. Their arms and tentacles have huge hooks that can be torn and hooked into the meat. Judging from the skin of sperm whales, the evidence is very obvious.
On the left (a) is the serrated sucker of the giant squid, and on the right (b) is the hook of the giant squid. Editor 1: As maximilian Bowman pointed out, the giant squid may not be as big as described in the picture below. However, a question mark indicates a lack of information.
Giant squid is very elusive because they live in extremely cold places and there are very few specimens for study. The collection of specimens depends entirely on luck, either caught by fishermen by accident or found in the stomachs of hunted sperm whales. In 2005, a group of Japanese biologists captured the lens of the first living specimen. It was not until 1925 that the first specimen and species were found. Since then, few complete specimens have been studied. The second complete sample was taken on 20 14, and the measured value was 3.5m ..
The largest intact specimen is about 5.4 meters long, which is much smaller than usually presented or estimated. Biologists estimate that the polysaccharide (chitin) beak of giant squid, which takes a long time to digest, was found in the stomach of sperm whale. The size of these beaks indicates the size of this animal. Some people think that the size of some squid can reach at least 10 meter.
They also mentioned the estimated size of giant squid and giant squid, and their relative damage to sperm whales. There are more specimens of giant squid to study, and the size is easy to record, as shown below (please note the truck comparison chart below), which was compiled by the National Evolutionary Comprehensive Center (the size is subject to the actual collected specimens).
From this, biologists can infer that if the giant squid does the least damage with its serrated sucker and it can reach a huge size, then the huge damage caused by the hook of the giant squid must indicate that they must also reach their own huge size (bigger? )。
