Chesapeake Bay Grasses
“eury” means wide
Organisms that are adapted to tolerate a wide variety of salinities.
Euryhaline organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly.
Some organisms are euryhaline because their life cycle involves migration between freshwater and marine environments, as is the case with striped bass and eels.
“steno” mean narrow
Organisms that can only survive within a narrow range of salinities.
Most freshwater organisms are stenohaline, and will die in seawater, and similarly most marine organisms are stenohaline, and cannot live in fresh water.
Includes crayfish, most species of trout, and darters
Rhizome – mass of roots
Turion - specialised overwintering bud produced by aquatic herbs
Monocot – single cotyledon
Dicot – two seed halves
