Why don’t insects live in the ocean?

Insects are found almost everywhere on Earth, but surprisingly, they don’t live in the ocean. A recent study explored why this might be, challenging the idea that insects can’t survive deep-sea pressure. Researchers discovered that the larvae of the lake fly Chaoborus edulis can dive up to 258 meters in Lake Malawi to escape predators. This is possible because of a protein called resilin, which helps their respiratory system withstand pressure changes. This finding suggests that insects could potentially survive in ocean environments, but it remains unclear why they haven’t adapted to live there permanently. The study highlights the complex relationship between biochemistry and ecology, but the mystery of insects’ absence from the ocean continues to puzzle scientists. QUESTION: Why do you think insects have not adapted to live in the ocean, despite some having the ability to survive deep underwater?
