Molgula manhattensis is small, spherical, brownish-grey in color, somewhat translucent, and feels soft and rubbery to the touch. Like other ascidians, they have two siphons (incurrent and excurrent), through which they draw water for ventilation and filter-feeding, and also for releasing their gametes. They are hermaphroditic, and release sperm and eggs into the water for external fertilization, unlike some other species of Molgula which may be viviparous (e.g. M. citrina). The tunic is covered with many little fibrils. Learn more about Sea Grape
