Popular Science Classroom: Squid

Squid is an important part of marine fisheries. It not only has high economic value, but also has a professional status in the marine ecosystem. It is a bridge for high-trophic-level marine organisms to obtain nutrients from primary producers, and it is also a source of marine food. An important channel in the net for hulls and conversions.

Squids generally live in groups, like most species in the animal kingdom. All squid like light at night, so when coastal fishermen catch them, they use lights to lure them to the water surface, and then use nets to quickly block their escape direction and capture them. There are a large number of pigment-containing "bubbles" on the surface of the skin of living squid, and these "bubbles" change with mood changes.

Modern medicine has discovered through research that although the cholesterol content in squid is high, squid also contains a substance-taurine, and taurine can inhibit the accumulation of cholesterol in the blood. As long as the ratio of taurine to cholesterol in the food you eat is above 2, blood cholesterol will not increase. The taurine content in squid is relatively high, with a ratio of 2.2. Therefore, when eating squid, cholesterol is only used by the body normally and will not accumulate in the blood. Most of the cholesterol in their bodies is concentrated in their internal organs. There is no need to worry about increased cholesterol intake due to eating squid.
