Appearance
''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, 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. The tunic is covered with many little fibrils.
Distribution
''Mogula manhattensis'' is native to the East Coast of the United States and to waters around Europe. It is also found on the West Coast of the United States and to parts of Asia.Habitat
''M. manhattensis'' can live from the intertidal zone to a depth of 300 feet. They can attach to solid organisms or even rocks, pilings, buoys, or sand. The sea squirts can also live in a temperature range of about 50 °F to about 80 °F. They can live in water with a salinity of 33.270 to 36.231 PSS, with oxygen concentrations between 3.960 and 6.328 ml/l.Food
Adults can live off of almost anything making them very good survivors in bodies of water though they prefer protected waters. The larvae can only live for a few days unless it attaches to a hard surface.References:
