Description
The Eastern Oyster (Crassostrea virginica) is a true oyster species native to the eastern seaboard and the Gulf of Mexico coast of North America. It is a bivalve mollusk with a hard calcium-carbonaceous shell that protects it from predators. Like other members of the same family, they can also make small pearls to surround particles that enter the shell. The pearls are insignificant in size and have no value. Like coral reef the Eastern Oyster’s oyster bed provides a habitat for a variety of species. As a filter feeder the Eastern Oyster sucks in water to filter out plankton and detritus to swallow; it then spits the water back out.

Dimensions & Sizes
Eastern Oysters have a length between 3”-8” (7.6-20.3 cm), width from 1.77”-4.92” (4.5-12.5 cm), height of 9.5”-2.6” (2.4-6.6 cm), and weight in the range of .88-1.98 lb (.4-.9 kg). The typical lifespan of the Eastern Oyster is 10-20 years.

What do gastropods eat?
Gastropods usually have a variety of diets and thus the food they eat ranges a lot. Some gastropods species eat algae from the rocks along the ocean floor while others may feed on large marine plants such as kelp. Some gastropods are bottom feeders and search the ocean floor for food.
Where do gastropods live?
Gastropods live in both terrestrial and marine environments, but most species of gastropods live in bodies of water all around the world. Some gastropod species live in coral reef habitats, but generally gastropods are considered one of the most diverse species in their habitats.
How do gastropods reproduce?
The way gastropods reproduce depends highly from one group to another as gastropods are a diverse group of animals. The majority of gastropods reproduce through internal fertilization. Gastropods are also capable of being either male, female, or hermaphrodites which gives them their unique reproduction system.

What do mollusks eat?
A mollusk’s diet may vary depending on its species. For example, mollusks that have their body between 2 shells are herbivores that eat algae. Meanwhile, squids and octopuses eat fish and other sea creatures. Mollusk snails can be either herbivores or carnivores.
How do mollusks move?
The way a mollusk moves depends if it lives on land or water. Mollusks that live on land move very slowly on a foot. Mollusks that live in the water eject water out of their body to move themselves. Some mollusks, like oysters and clams, do not move but rather attach themselves to a rock or a surface.
How do mollusks breath?
Aquatic mollusks breath by using gills, called ctenidia that are in their mantle cavity. Mollusks that live on land do not have gills and breathe through their mantle cavity that has a surface lined with blood vessels. Diffusion of air happens through the moist skin of mollusks.

How do invertebrates protect their soft bodies?
Invertebrates can effectively protect their soft bodies through an outer hard casing that is referred to as the exoskeleton. Invertebrates like spiders, crustaceans, and insects have their exoskeletons made through sections of jointed legs. Others like mollusks like snails and clams have a hard shell in which they can hide when danger is present.
What is the difference between an invertebrate and a vertebrate?
The difference between an invertebrate and a vertebrate is that invertebrates have no backbones while vertebrates have a developed internal skeleton with cartilage and bones as well as a developed brain that is protected by a skull. Vertebrates also cannot make their food, while invertebrates make their food.
Why are invertebrates important?
Invertebrates are important because like bees they help with pollination, as well as help clear and clean up the environment. Invertebrates are also important because they are soil aerators and creators as they help grow food crops. They also provide eco-system balance and serve as food for other species within the food chain.

What do marine animals need to survive?
Factors that marine animals need to survive include bioluminescence which is when animals make their own light and helps them communicate and scare predators. Constant light, pressure, temperature, and food are factors needed to remain stable and help marine animals evolve to survive. Marine animals that live within the deep sea can withstand the cold.
Why do we need to protect marine life?
Humans need to protect marine life because our actions and lifestyles have a direct impact on the ocean. We need to protect marine life and provide a safe and healthy environment that is not impacted by overfishing, climate change, pollution, habitat destruction, invasive species, and other forms of human exploitation.
What is the most common animal in the ocean?
The most common animal in the ocean is the bristlemouth which is a vertebrate, an animal with a backbone. The bristlemouth is a tiny fish that can glow in the dark and has fangs that resemble needles. Bristlemouths are part of the 1 million species of animals that live in the ocean.

How do animals adapt to the coast?
Animals adapt to the coast by adjusting to living in salty water as well as being able to withstand being covered or uncovered by the tide. Further coastal adaptations also include being able to hide or escape quickly from predators, finding food, and staying in a safe place as the tides move.
Why are coasts important for wildlife?
Coasts are important for wildlife because they serve as nesting grounds for species of sea turtles as well as are habitats for animals like beach mice. Coasts are also important foraging areas for migratory shorebirds. Coasts are important as they are used in cohesion by all species of animals.
How does coastal erosion affect animals?
Coastal erosion affects animals and humans as it causes sea levels to rise, flooding, as well as stronger waves. Coastal erosion also causes the gradual loss of land that is important to many animals. Coastal erosion is when a portion of land is lost within a shoreline by either natural events or manmade decisions.

How do animals survive in estuaries?
Animals survive in estuaries by adapting to the harsh conditions of their habitat. Estuaries either have salt water or fresh water. Animals survive by adapting to live in the different types of conditions and remaining in the regions of the estuaries where they are most comfortable and have consistency.
Why do fish lay eggs in estuaries?
Fish lay eggs in estuaries because these habitats offer a great amount of food availability for the development of young fish while also providing protection from predators. Estuaries are often used as breeding grounds by many species of fish due to these factors and are considered highly valuable.
Why are estuaries important for birds?
Estuaries are important for birds because estuaries offer a mix of nutrients from both the land and sea, creating a rich ecosystem. Since estuaries house numerous species of fish, they also create a food source for birds. Birds also use the beaches next to estuaries for feeding, resting, and breeding.
