Nurtures fish. Vallisneria americana, commonly called wild celery, water-celery, tape grass, or eelgrass, is a plant in the family Hydrocharitaceae, the "tape-grasses". Eelgrass grows in salty, tidal waters, on sandy, gravely and muddy sea floor, in areas with temperate climate. It is endemic to just two localities: Langebaan Lagoon on the west coast, and Knysna Estuary on the south coast, and occurs only on the eelgrass Zostera capensis.In Langebaan Lagoon, eelgrass has fluctuated substantially over the last 34 years, and S. compressa has twice approached extinction. They are on the OSPAR List of Threatened and/or Declining Species and Habitats (declining in Region II – North Sea and Region III – Celtic Sea, and threatened in Region V – Wider Atlantic). The designation as EFH requires federal agencies to consult with NOAA Fisheries on ways to avoid or minimize the adverse effects of their actions on eelgrass. Eelgrass is a type of aquatic plant that belongs to the seagrass family. Reg. About 30% of the world’s eelgrass has vanished since the 1870s. hެ�[k1����Ռ�]A0�R����MC�6��Yp�`oB��{Fk78��Bd�f�4�=�Wr��$wd���Ɋ���s�]�\P�LGGf�{g���v��gA�������z^�x����>@�Yϻ]3Z���~+Q��g9��$k%*���|;�v�s2��m5' I=���vV����?�ysC^��w�U��i(�a��:�-�Ŗ\���'o#uW��l&q���zY1��ԛFN��ʜ�]~�0(�������˹9i���V�eE��Z>��X��\4��%�㧻*���l�f�1W�. – American eelgrass.

The exception to this is the Green Turtle and Leatherjacket fish which feed directly on seagrass like the Eelgrass. Eelgrass is one of the most productive and valuable resources on earth. Biggest threats for the survival of eelgrass in the ocean are pollution of the water, habitat destruction, oil spills, intense boat traffic (propellers mechanically destroy eelgrass) and changes in water temperature. Its distribution ranges from central Biscayne Bay (north of Virginia Key) to Sebastian Inlet. Two species of eelgrass offer similar ecosystem services but inhabit different elevations in the estuary. Industrial, residential and recreational development and activities continue to put eelgrass communities under pressure and have resulted in the loss of a number of historic eelgrass communities, especially in places like Vancouver Harbour. There are 16 species of eelgrass that can be found in the coastal wetlands, estuaries and shallow bays around the world.

Japonica generally grows higher in the intertidal zone, and marina grows in deeper water. Common eelgrass is a plant species (not a seaweed) that lives on the very low shore down to 10m deep and can form dense seagrass meadows. These meadows form important underwater habitats in shallow seas, providing shelter for many species, including seahorses and pipefish.
