    Molluscs have a common trait and that is that their bodies are all soft. Among them, mussels and snails are very slow to move and are easily attacked by predators, and in the process of long-term evolution, they have formed shells that protect their soft bodies. River mussels have two petal-shaped shells, and snails have a spiral-shaped shell.

    If you dissect them separately and look at them, you will see that their soft bodies are also covered by a fleshy membrane called the mantle. The mantle also plays a protective role. Shells are formed from substances secreted by the mantle.

    The head of the squid has two large, well-developed eyes. Below the head, the trunk is covered with a capsule-like mantle. Squid move quickly and can flee quickly when attacked by predators.

    In addition, the squid has an ink sac in its body, which contains thick black ink, which can quickly spew out when encountering enemies, staining the surrounding sea water black and covering its escape.

    The zebra is a herbivore endemic to Africa and looks like a horse, but the biggest difference from ordinary horses is that it has a beautiful flower dress, with a black and white strip on it, black and white, as if it is a beautiful pattern drawn artificially. Kinesiologists tell us that these patterns are actually theirs"ID card"。Because different zebras have different markings on their bodies, some are thick and sparse, and some are fine and dense.

    Members of the zebra family use markings as a marker to identify their own kind.

    Black and white have different procedures for absorbing and reflecting light, so the contours of a zebra's body can be disrupted, blurring its shape and making it difficult to distinguish. Therefore, the stripes on the zebra are a protective color to adapt to the outside world.
