How Do Clams And Mussels Work Together
They type of body cavity coelomate: pericardial cavity
Body organs make up the visceral mass and are protected by the mantle which secretes the shell.
They have an open circulatory system
Clams shells are thick while mussels are usually thin. Mussels live attached to something while clams live in the sand. Clams live alone, while mussels are usually in large groups.
The oldest part of a clam’s shell is called the umbo and is located at the hinge of the clam.
The rings on a clam's shell indicated how old the clam is.
Its part of the mantle, where the water is directed from.
The hinge holds the two shells together.
The muscles that open and hold the clam are called hinge ligaments and adductor muscles.
The function of the tooth-like projections at the dorsal edge of the clams valves is to help the two valves completely close.

Its function is to keep it in secret.
Clams breathe through gills.
Two siphons help direct water over the gills.
The palps are found very close to the mouth, and their function is to guide food into the mouth.
Clams take water through the incurrent siphon, and then it moves over to the gills. The food then goes to the mouth, then to the esophagus to the stomach, then to the intestine, and then it finally exits through the excurrent siphon.
The clams heart is located between the digestive gland and the muscle.
The parts of the clams nervous system is all connected by nerves from ganglia which is the anterior, foot, and posterior.
Clams are referred to as “filter feeders” because they feed off of tiny particles in the

    Marine organisms that have a larvae stage dependent on wind waves to move and settle in an environment, where they develop to adults and recruit. The Mytilus californianus has a larvae stage and as the waves break into the surface of the pier pilings in Santa Monica, the larvae stick to the hard substrate that the vertical columns provide. The random placement of the larvae on the pier piling is what determines how much stress and nutrients that individual larvae will receive as it develops to an adult. Studies conducted in a lab with different mussel species have shown that growth is determined by the nutrients it receives and the quality of nutrients…

    Most starfish are carnivorous they prey on animals such as oysters, mussels, sea snails, and also clams. They find their prey with light sensing eyespots. These eyespots are located at the end of each of their arm. One is also located in the center of their bodies. It can only sense light and dark. They pry open the oysters with suction-cupped feet by wrapping their around the oyster shell and then pushes it stomach through its mouth and into the open shell. A starfish have two stomachs. They are call the cardiac stomach which is a sac-like organ located at the center of their bodies and then it the pyloric stomach where the digestion is completed. This adaptation allows starfish to eat animals larger than their…

    However, the gill arches during the embryonic stage create similar structure in use, not appearance. The first gill arch creates “the trigeminal nerve in both humans and sharks” (Shubin 91). The cells of the second gill arch gives us cartilage and muscle that helps the creation of the stapes, as well as another bone, the hyoid, that assists in swallowing. In a shark, the same arch “helps with jaw production” that compares to hyoid (Shubin 92). In the third and fourth gill arch, for humans it produces structures necessary for speech and swallow and for sharks it includes parts of tissues that support the gills. Sharks and humans have gill arches in the embryonic stage, but unlike the statement proposes, they do develop into related structures in each…

    I chose to look up a diagram on a sea dwelling organism known as a Jellyfish. Jellyfish have many different forms and are often characterized in different groups. One jellyfish that stood out to me was the Aurelia or also known as the Moon Jellyfish, which is like the basic jellyfish that I’ve always seen in pictures and books growing up. Jellyfish are said to be very effective predators, as one point in the time they were considered to be at the top of food chain. Being effective predators makes them physically fit to be in any environment that they travel to. Even though most would say that jellyfish are horrible swimmers, they are actually in fact many are very strong precise swimmers. Jellyfish can swim horizontally and vertically by using contraction against their bell to expel jets of water to propel them. One drawback of them not being stronger swimmers like larger fish is that they often get caught in sea currents and get stuck in them as they go pass. The bell that propels them has a thick ring of strong muscle, called the coronal muscle. That muscle generates most of the power and energy used by a jellyfish. Now hanging from their subumbrellar is a projection called the manubrim which has the mouth its terminus. The mouth is often surrounded by oral arms normally just for but can sometimes be a multiple of four such as eight, depending on the type of species. Jellyfish don’t have a brain but they do bear a sophisticated computer which tends to all its needs and functions throughout the jellyfishes body. Though not as complex as a normal brain, it does suit the jellyfish well. Now on the edge of the underside of the jellyfish’s bell are its tentacles. The tentacles too can range in different numbers and sometimes some have thousands. These tentacles can be used to feed it, but also are use as it self defense mechanism to protect and also to hunt. The body and tentacles of a jellyfish can discharge…

    The primary swimming form of the Orangespotted Sunfish is labriform because they row their pectoral fins, an oscillatory fin motion. The mouth of these fish are terminal and moderately large. A terminal mouth allows this species to be a benthic and surface feeder. Their gill rakers are long and slender with space between them. This allows for particles in the water that flow into the mouth of the fish that they do not want to eat, to flush out. It indicates that the food of this fish is medium to large sized compared to their body. This correlates with an omnivorous diet and the ability to consume small and large prey. Daphnia and Cyclops are crustaceans often found in this species’ diet. Also, they help with mosquito control by feeding on mosquito larvae. The eyes of the Orangespotted Sunfish are corrected for spherical aberration, meaning they are a visual fish and need sight to find their prey. Since their prey is small fish and crustaceans, good eyesight is important to find them in the murky water that they live in. The Orangespotted Sunfish has adapted traits to better thrive in it’s…

    Morphology of Molluscs-they have a soft body they are more fragile. They also have more difficulty to support their bodies in terrestrial environments or to fixate to substrates in aquatic habitats. Many species solve these problems by secreting a calcareous carapace, or shell, an exoskeleton to support and protect them and to prevent dehydration.…

    The Orangespotted Sunfish

    The compressifrom body shape is not as favorable for fitting into small spaces as the anguilliform, eel-like, style but with the small size of these fish and a larger amount and variety of refuge or cover found in rivers, they survive quite well. This compressiform body style allows this fish to make quick turns and short, fast bursts of speed with good maneuverability. The caudal fin is forked with a low aspect ratio meaning the tail is broad, the fish has good acceleration from the start, and the tail aids in hovering. A forked tail allows for good acceleration and maneuverability with a slight amount of drag. The dorsal fin has ten anterior spines that are directly connected to the rays of the posterior dorsal fin. Spines help protect this fish from predators and keep them balanced. The anal fin, outlined in black, also has three spines for extra protection. They have short and rounded pectoral fins which contribute to speed and allow the fish to fit into small crevasses. The primary swimming form of the Orangespotted Sunfish is labriform because they row their pectoral fins, an oscillatory fin motion. The mouth of these fish are terminal and moderately…
