The oyster drills help with the food chain through out the bay. The sea cucumbers help to keep the bay clean. The herring gulls help to clean the bay.

Oyster Drills

Oyster drills are important to the bay’s food chain. Oyster drills live in saltier water in the middle and lower part of the bay. They sleep in oyster beds. Oyster drills are apart of the gastropod family. Oyster drills are important because they eat small shellfish. If they don’t they will die. Its important they do because then fish, birds, and blue crabs will die. If blue crabs die fishermen have nothing to catch.

Sea cucumbers

Sea cucumbers are important to help the bay be clean. Sea cucumbers are sluggish and slow moving. Sea cucumbers mouths are made of sand and mud. Sea cucumbers eat dead or decaying plants and animals. If they don’t the whole bay will be filled with dead and decaying plants and animals. If they don’t eat they will die. If they die turtles, crabs, and fish will die. If they die we wont have a lot of seafood and the bay will be filled with dirty an decaying plants and animals.

Herring Gulls

Herring gulls are important to help the bay be clean. Herring gulls are found in sandy beaches. A group of herring gulls are called Flotilla. Herring gulls eat dead crabs and clams. They also eat garbage and insects. If they don’t eat garbage it will fall in the bay. If garbage falls in the bay it will kill all the other animals. If they die pescaterian could die because that is there only source of protein.
