The conch is a mollusk that lives in the ocean and is a relatively common animal in China.In terms of category, although conch is not a high-level animal, it still has some basic body structure, which can play an important role in its life activities.Among them, the antenna is an important organ.Sea snails have antennae that are attached to their soft parts, closer to the mouth of their shells.The antenna of the conch is used to detect the surrounding environment and has a very important sensory role.So sometimes we see conches putting their antennae out into the mouth because they're probing the environment.
In fact, when buying conch, we can judge whether we are buying dead conch or fresh conch by testing whether their tentacles are retracted.This is because the living conch often feelers out to perceive the surrounding environment, at this time can contact their mouth, if found in time to retract the tentacles of the conch, indicating that the conch is alive.In addition, there are many other structures near the antenna of the conch, such as two granular things, that is, their brain nerves, which can not be eaten.
As mentioned above, the conch has antennae, which can be used to sense the surrounding environment.Humans and many other animals have a nose, a sense of smell, and the ability to sense their surroundings.However, as a lower mollusk, the conch does not have a nose.In fact, they have enough antennae to judge whether the surrounding environment is safe or not, so as to carry out various life activities.
