Credit River SC - Plankton Traditional Cache

This is one of the Credit River Sea Creatures series of caches and is intended to be done while floating down the Credit River in a tube or canoe. A sequenced list of all of the caches in this series from Norval to Eldorado Park is available.

Plankton are a very diverse group of organisms comprising thousands of species that float in the ocean since they lack any significant means of propulsion.  Most species are microscopic and some can carry out photosynthesis (phytoplankton) and others cannot (zooplankton) and these in turn feed on phytoplankton.    Plankton form the basis of the marine food chain and provide food for larger sea creatures including some whales.
