Under what circumstances can you paddle and not "abalone"

Changes in pressure and flow. According to the query of the culture network, abalone excretes waste and water in the body through the anus in the ocean, and these water flows will form a drawing water flow due to the change of pressure and flow rate after leaving the abalone body. This silky water flow is actually an adaptive mechanism for abalone to survive in the ocean, which can maintain the balance and health of the body.
