White Abalone Research Paper

Biologists Robin Seeley conducted an experiment in which she gathered periwinkle snail shells on Appledore Island and measures their thickness. The time period in which she has found the snails was before the inhabitation of the European green crab. Eighty years later, the shell thickness of the snails were measured again and recorded. This time, the inhabitation of the european green crab has increased significantly and the thickness of the snail shells has increased. She has concluded that when the crabs arrived on the island, they began to eat the thin shelled snails because their shells were easier to crack.

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

In Order to analyse the Distribution of C.brunneas and L.scobina, Year twelve Biology classes had to go down to the “ Sirens’ Rock” on the south coast of wellington. The Habitat is mainly rock but there are rock pools from when the high tide went down the water couldn’t get out. Chamapsipho brunnea or Brown Barnacle are a type of barnacle found in the mid-high tides parts of rocky shores. Brown Barnacle are also known as filter feeders so they feed off of algae and plankton. Brown Barnacle are not found in the low tide zones for this reason their shells can close off meaning that they can survive out of water longer by keeping water locked in their shells. Lepsiella Scobina or oyster borer are a predatory sea snail species. they feed off of barnacle and other prey they are found in the mid-high tide zones of rocky shores and not low tide. Oyster borer are frequently hidding in crevices to hide from predators. Oyster borer are not found in high tide but mid-low tides as they can not close their shells off completely

The killer shrimp is a combination of shrimp and a pray mantis. They are dangerous and have incredible abilities, having an incredible strength compared to their size. They got powerful appendages that can be used for hunting or for self protection. The mantis shrimp is a territorial animal, and the individuals of that specie usually fight for shelters. Their appendages work like hammers, what provides a strong impact force.

Today’s eastern oysters range from 3 to 5 inches in length, sometimes as much as 8 inches, although the oysters present during the colonization of the New World were documented to grow much larger (“Oyster History”). Oysters have many great characteristics in regard to their utility for humans as well as wildlife. The build ups of oyster bars, reefs, and beds provide habitat for many aquatic lifeforms and the filtration capabilities they possess is quite remarkable; as filter feeders, oysters feed on phytoplankton and small organisms while removing nutrients from the waters the inhabit, leaving them clear and pristine; just one oyster can filter more than 50 gallons in a day (“Oyster History”). Alas, it was a palatable constitution that made the eastern oyster so popular, creating an extensive economy based on its harvest. Unfortunately, this considerable popularity would ultimately bring the oyster’s

Oyster reefs, giant populations of oysters, provide habitats for many other types of organisms such as worms, snails, sea squirts, sponges, small crabs, and fishes.

Shells before 1884, were high-spiraled with thin walls. Compared to the shells found after 1884 were low-spiraled with thick walls. After doing some research, Seeley found that an intertidal crab, Carcinus maenas, had sought after the snails for food.(Seeley) It was found that the shell size had changed due to the harmful

Imagine living at the bottom of the sea with little food to eat and you are suddenly caught. You realize you are coming up through the sea. You are pulled out from the water and you are having trouble breathing. The fishermen throw you onto the deck of the boat and you suddenly realize you have just lost everything but then after the picture is taken they throw you back into the sea. You swim back to the bottom of the sea and see your mate and babies. The blob fish was allowed to do this because they respond to the environment, reproduce, gets energy, exchanges gases, and

The blue crab, Callinectes sapidus, is one of the most familiar inhabitants of marshes and waterways along the Atlantic and GMx coasts of North America. The abundance of blue crab larvae and juveniles make them important components of the diets of numerous species of fish, invertebrate and avian predators (Van Engel 1987, Guillory and Elliot 2001). As juveniles and adults, blue crabs act as generalist predators on benthic infauna and epifauna; consuming invertebrates, fish, and crustaceans (including other blue crabs) as well as plant and detrital materials (Darnell 1958, Alexander 1986, Meise and Stehlik 2003, Lipcius et al. 2007). It has been proposed that blue crabs are keystone species in the marsh because of their impact as predators

Food. The first bite when it hits my taste buds give me shivers. The aroma it has that screams eat me. Everything about it lightens my mood. Red Lobster, unfortunately has none of those effects on me. Red Lobster… never will I go again. High prices for low quality food, I don’t get what all the hype is about it. The cheese biscuits, they're fine but they taste nothing like heaven. Everything about Red Lobster is horrible. Never am I wasting my money on that non-seasoned, nauseating food ever again. Joe’s Crab Shack on the other hand is one of the best to ever serve seafood.

The blue crab population in the Chesapeake Bay was considered to be a surplus from the 1950s to around the 2000s as well as in the Bay’s tributaries (Stagg & Whilden, 1997). The blue crabs in Maryland live for about three years (Stagg & Whilden, 1997). This is part of the reason that it’s so important that a high level of blue crabs is maintained so that they’ll be able to produce offspring future generations. Approximately 75% of the entire blue crab population is made up of the crabs in Maryland (Lui, 2015).

I kicked past a white coral cluster. Dozens of tiny, neon blue reef fish hid in its branches. A red goby popped out of a crevice and zipped back into the crack when he saw me. That's when I spotted it - the perfect shell for my collection. A large, cylindrical olive shell glinted below in the sand. I took a deep breath from my snorkel and

Currently researchers are collaborating with public zoos and aquariums to collect eggs and utilize what would otherwise be an unused resource. After five larval rearing trials were conducted, researchers have been successful in rearing larvae to 18 days post hatch which is a milestone in raising blue tangs for aquaculture (Cassiano et al., 2015). When we start looking towards using captive bred blue tangs for use in personal aquariums we are able to decrease our dependence on the capture of wild populations. As a result stresses put on the reef such as depletion of reef resources and habitat degradation should decrease (SEAFDEC, 1999).

In an article, Plastic and Heritable Variation in Shell thickness of.. associated with risks of crab predation, the intertidal snail Nucella lapillus has thicker shells where there is wave action in which crabs are abundant and pose a high risk of predation than those are not at the exposed sites. A thicker-walled shell at sites sheltered from wave action influenced the vulnerability to crab predation. Crabs tend to be more numerous at sites sheltered from wave action or longer periods at a low tide shore. Sites exposed to wave action or higher shore levels, increased the resistance to dislodgement (AUTHOR 3). Shell morphology have been showed to be under heritable and plastic

Sirens Rocks is a rocky shoreline located along Wellington 's Southern Coastline inbetween Island Bay and Owhiro Bay. Along the shore there are many different species distributed within the intertidal zone. During my visit to Siren 's Rocks i was able to witness many of these species, including 2 species of true limpets called Cellana Denticulata and Cellana Radians. Cellana Denticulata, commonly known as the "denticulate limpet ' is a marine gastropod belonging to Nacellidae family. its cone like shell possesses a brown or grey toned exterior with a paler bluey white interior. In order to feed, a patellaogastropoda (scientific name for true limpet) such as C.Denticulata uses a ribbon like tongue with rows of teeth to scrape algae of the substrates they live on. Cellana RAdians are also a gastropod Mollosc, also belonging to the Nacellidae family. (Nacellidae means a "taxonomic family of sea snails or true limpets, in the clade Patellogastropoda") This means that like the Denticulate Limpet, Cella Radians feed by grazing algae with thier radula. They possess a lightish grey shell with darker ribs but a generally smooth shell unlike the Denticulate limpet. both limpets are found on the rocks or other hard substrates, usually on the southern side. Subtidal limpets such as the denticulate limpet and radiate limpet are often covered in a layer of green algae also. This makes them harder to spot as they
