These insect submariners survive depths that should crush them
✦AI Summary
Insect larvae in Lake Malawi survive extreme underwater pressure by using specialized air sacs that function like submarine ballast tanks. These sacs, made of elastic resilin, allow the larvae to migrate vertically through deep, low-oxygen waters.
Deep-diving insect larvae in an African lake are forcing scientists to reconsider a popular explanation for why insects are almost entirely absent from the open ocean. Their secret is a remarkably durable system of air sacs that can tolerate far more pressure than researchers expected.
