Sea squirts breathe through a process called filter feeding, which involves drawing water into their bodies through an incurrent siphon. As water flows through their bodies, they extract oxygen and other nutrients, then expel the filtered water through an excurrent siphon. The oxygen is absorbed by specialized cells within their pharynx, allowing them to respire efficiently. This method is particularly effective given their sedentary lifestyle as adults.
