investigation of Blueskin Bay Warrington trip was concentrate to study the community pattern of
that place. We observed a variety of life there, including cockles, oysters, mud snails, mud whelks, crabs
and wedge shells. Blueskin Bay Warrington is an estuary. Which means estuaries and their
surrounding wetlands are bodies of water usually found where rivers meet the sea. Estuaries are
home to unique plant and animal communities that have adapted to brackish water, a mixture of
fresh water draining from the land and salty seawater. This means that Blueskin Bay Warrington is
formed where freshwater from rivers and streams mixes with salt water and flows into the sea. The
habitat consists of mudflats, coastal wetlands formed when mud is deposited by high and low tides
or rivers.
