The dried flesh of sea cucumbers is a delicacy in Japan and Taiwan, and overfishing has threatened some populations. A high density is vital to sustain a population as they reproduce by releasing sperm or ova into the water; other sea cucumbers must also be releasing sperm or ova nearby.

1. morski krastavac

muški rodživotinja

Morski krastavci gutaju blato i pesak da vare hranljive sastojke. Oni su usavršili tehniku špricanja, tj. povraćanja u cilju samoodbrane. Oni ne povraćaju samo ono što su pojeli, već čitav sistem za varenje i respiratorni deo, čitavu svoju utrobu. To iznenadi napadača i u potpunosti ga odbije. Morski krastavci imaju veliku sposobnost regeneracije. Oni istovremeno izbacuju svoja jaja i spermu u vodu. Oplođena jaja razvijaju se u plivajuće larve i smeštaju na dno gde se pretvaraju u minijaturne krastavčiće.
