tunicate
Blue spot sea squirt (Clavelina moluccensis), a colonial tunicate.
In primitive tunicate species, eggs are fertilized externally in the surrounding water, where development also occurs. However, many tunicates retain their embryos within the femaleās atrium or other internal structures until the larval stage has developed. While internal fertilization is common among various tunicates, the specific location of fertilization depends on the species' reproductive strategy.12
