Horseshoe Crabs Research Paper

Do you know that Maine is famous for lobsters because it harvests the majority of lobsters in the United States? The population reached to 1.336 million people living in the state of Maine. And the total area of Maine is 35,385 square miles, also known as the biggest state with the most land from the original 13 colonies.

This perspective often distorts the view of large crabbing businesses on their harvesting methods which, although are seemingly humane, are actually very detrimental to the crab population. For instance, when Hal Herzog, a Professor of Psychology at Western California University, ventured to Florida’s Gulf coast, the crabbers there explained to him the two varieties of crabs which they harvested; the “lucky” stone crabs and the “unlucky” blue crabs (Herzog). The blue crabs were considered unlucky because they were killed on the spot; however, the stone crabs were considered lucky because of their ability to regenerate their claws, and so crabbers would simply rip their claws off and then throw them back into the sea (Herzog). However,

Reaching a length of up to 5.5 centimeters (or about 2 inches), the bigclaw snapping shrimp is the largest member of the family Alpheidae, which are also known as the pistol shrimp. It is found in water up to 30 meters (98 feet) deep from as far north as North Carolina’s Outer Banks to the Brazilian coast. It also is able to survive in areas of rapidly different salinity; A. heterochaelis has be found in environments that range from mesohaline (having a salinity of 5 to 18 parts per thousand) to hyperhaline (having a salinity of 40+ ppt). This means that it lives in environments that range from brackish to seawater of above average salinity. It is most commonly found in areas where cover can be easily found during the day, such as an oyster reef.

CHARLESTON, South Carolina (Achieve3000, August 7, 2015). A rare leatherback sea turtle was found on a South Carolina beach in March 2015. The enormous reptile weighed 476 pounds (216 kilograms). It was spotted on the Yawkey-South Island Reserve in Georgetown County. The creature was brought to the South Carolina Aquarium. Workers named her Yawkey. She was treated with fluids, antibiotics, and vitamins. She was the first leatherback to be found alive in South Carolina. Caretakers were eager to see her returned to the sea.

Warren's Lobster House is located on the southern tip of Maine's coast and serves the freshest seafood, lobster and fish. The family-friendly restaurant also has chicken, steak and other seafood available. Warren's Lobster House is a destination restaurant perched on top of wood pilings above the waters of the Piscataqua River. It's located on US 1 and has been open since 1940.

It shares ancestral background with shrimp and lobsters. They are omnivores with their prey being mussels, fish, plants, and smaller blue crabs (Society). Although the Blue Crab is well established within its ecosystem it is highly sensitive to environmental and habitat changes ("Blue Crab, Maryland State Crustacean", 2016). The detrimental conditions of the Chesapeake Bay have affected the populations of Blue Crabs along with over harvesting.

Imagine that a huge wave crashes down on you. Then it drags you back into the ocean. On your way you pass by an animal that is clinging on for dear life. In order to survive in these harsh conditions, animals need adaptations. An ecosystem is a biological community of interacting organisms and their physical environment. The California Spiny Lobster lives in the neritic e zone which is in between 200 meters and 0 meters. It is located on the continental shelf. They like living in coral reefs and the ocean ground. In order to survive in the neritic zone with predators, sea floor hiders, and other environmental threats, animals need adaptations.

Horseshoe crabs live in the Delaware Bay and give birth to their offspring there. At this time the red knots, a type of bird, migrate to the area to collect food. The food they collect is the newly conceived horseshoe crab eggs that are buried along the shore sand.

The name of the band that I went to go see were called Rock Lobster. It is a band is made up of several people and may be accompanied by guest. The main names of the band are Stephanie Foxx, Jessica Jackson, Dallan Baumgarten, John Colby, and Gary Sanchex. They are a band that plays the most popular of 80’s rock music. I attended this event on June 5, 2016 at 7:00pm. It was located at in Scottsdale at McCormick-Stillman Railroad Park. The exact address is 7301 e Indian Bend Rd, Scottsdale, AZ 85250. The instruments that were used during this event was a guitars, drums set, and a single voice. The set was very small, everyone played their instrument while the one main guy sang. All of the music that they played was very strophic. Some of the

The argument the author puts forth is that horseshoe crabs have evolved over the eras. That they’re not “living fossils”. Horseshoe crabs have “rounded cephalic shields, that were like the extinct trilobites, and an arrangement of legs and gills”, no wonder people think they are living fossils. This is the beginning to how these historic animals have evolved.

“They see something, walk up to it, pick it up, and maybe beat the crap out of it,” says Justin Marshall, referring to a commonly unknown creature called the Mantis Shrimp. This species often goes overlooked and unnoticed by most of the world and not just because it only grows 2-7 inches (“Peacock Mantis Shrimp” 1). Since it is such an unknown animal, many people do not know what it is or what makes it remarkable. How can the small mantis shrimp, a crustacean whose appearance is more like that of a clown than a ferocious beast, be worth noting in the different fields of science? They are more interesting than they seem. Mantis shrimp possess a vast array of fascinating physical features that set them apart from other sea-dwelling animals: their clubs

The horseshoe crab and the trilobite do share a common ancestor. There are many pieces of evidence in the anatomy of both species that support this claim. A first piece of evidence is that both species have an outer exoskeleton but no internal skeleton. This separates both of them from vertebrates, making both of them invertebrates. The second piece of evidence supporting walking legs of both species are also positioned on the underside of the animal, protected under the shell. Both the trilobite and the horseshoe crab have one horseshoe-shaped cephalothorax with a raised ridge in the middle of it and two eyes positioned on either side of the ridge. The mouth of both species is on the underside of the body as well, unlike crustaceans and insects

The fishery for Caribbean spiny lobsters is well known in the Florida Keys and is one of the major industries that influence Florida’s economy. While this is a large and fruitful industry in the Florida Keys, it also comes with its disadvantages, particularly the traps that are used to catch the lobsters. There are many trap debris or ghost traps left in the water for various reasons but with debris like ghost traps they continue to catch lobsters that aren’t being taken from the trap so they become diseased or damaged if they even survive before the traps have sat there long enough to start breaking down. Diseases are able to be transmitted more quickly once lobsters are caught in the traps and healthy lobsters

Approximately, two or more weeks after the eggs have been laid, larval horseshoe crabs will emerge from the eggs. These larva then migrate to near shore waters and settle on the sandy bottom of tidal flats where they will further develop for another year or so (National Wildlife Federation 2015). As the horseshoe crab larva develops over these next few years, it will gradually move to deeper water and begin eating food more typical of an adult. Limulus polyphemus will reach reproductive age after about ten years. During these years and those after, horseshoe crabs will molt shedding their exoskeleton allowing them to grow a larger shell for their growing size (National Wildlife Federation 2015). Horseshoe crabs will typically molt 16 or 17 times during their
