Crab Essays

King crab is recognized for its aquaculture potential, but several biological and ecological aspects are still unknown from the species, including the ontogeny before the larval stage. It has been assumed that, like the others “spider crabs”, it exhibits sexual dimorphism and three stages of maturity, distinguishable by phenotypic differences: (I) juvenile, (II) intermediate and (III) adult. To address these assumptions, we performed morphometric landmark analysis on the carapace of 325 individuals

by horseshoe crab blood that was drawn from horseshoe crabs. We should interact with horseshoe crabs even though they are a keystone species because we can use their benefits and also help them too. Some ways that we can preserve their species and simultaneously gain benefits is by flipping them over when they are stranded, chitin, and helping them rebuild their breeding habitats after human causes or natural causes such as tornados, and hurricanes. Have you ever seen a horseshoe crab overturned

named Michael, who lives with his Aunt Esther after the death of his parents. In the beginning, Michael and Aunt Esther fight with one another. Soon, Michael brought home a hermit crab named Sluggo. Michael and Aunt Esther start to make a good effort to fix their broken relationship with one another mainly over the crabs. In the end, Aunt Esther and Michael now have a good bond and apologized for fighting with one another. This story shows that Michael and Aunt Esther change throughout the story

Chasing the Dream-What’s Happening Around the Galapagos in January January marks the beginning of the warm season in the islands. As the air and water temperatures rise; daily rain showers leave behind lush vegetation and vibrant, sunny skies for a Galapagos vacation that takes your breath away. Exotic by nature, the archipelago comes alive in the new year as many of its creatures wait for the warm season to breed. Green sea turtles lay their eggs, land and marine iguanas start to mate, and giant

The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

The bright morning sun stuns my eyes as the pleasant ocean water of the Gulf of Mexico warms my teenage body. Hundreds of us (Tarpon) swarm around blue crabs that are bunched up around this sixty foot trench about a mile offshore. We are stocking up for our annual “run” we like to call it down to the dreaded pass, which has claimed many of my family members is the years past. From the knowledge I have obtained over the years the pass is located at the end of Gasparilla Island, every year starting

Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations. These

a) Fiddler crabs are semi-terrestrial crabs that are also known as crustaceans, and they are a part of the genus Uca. The female fiddler crabs have the same claw size, while a male has one claw that is noticeably larger than the other one. These crabs get their name due to the male’s smaller claw grabbing food and putting it in his mouth because it looks someone is playing a fiddle with a bow. They also have square-shaped bodies and are known to live on marshes, beaches, and mud flat lands, which

was cool to see palm trees it was the first time i had seen one in person and they are really cool. Another fun thing was all the animals that i spotted throughout the trip. One of them was a crab, there are many different kinds of crabs such as a king crab and a coconut crab. I am not sure what kind of crab the one i saw was. My friend Levi’s dad Joe tried to catch it and it pinched his finger and made it bleed. After that he kept trying to catch it and he finally succeeded. It was very interesting

After a giant pine cone fell on Sean Mace, 50, he filed a lawsuit for more than $5 million. While this lawsuit may sound ridiculous, the pine cone weighed more than 16 pounds, and caused a severe brain injury for the man. The pine cone fell from an Araucaria bidwillii, which is a tree that is native to Australia. This tree is better known as the false monkey puzzle tree. At their largest size, these pine cones can reach up to 16 inches in width, and they can weigh more than 40 pounds. As you can

capelin eggs in red king crabs at an ambient temperature of 2.9°C, which is within the range of bottom temperature at capelin spawning sites along the coast of northern Norway (Sætre & Gjøsæter 1975). The experiment ran between March 27 and April 6 2011. The collection of experimental animals and capelin eggs is described in Mikkelsen (2013). To obtain at least one datum per hour of digestion time, 36 crabs were expected to be sufficient for this experiment. Red king crabs were captured using traps

Dungeness crab (Metacarcinus magister) Introduction: The Dungeness crab, Metacarcinus magister (formerly: Cancer magister), is also known as market crab, and San Francisco crab and belongs to the family Cancridae. The common name of this species comes from the port of Dungeness, Washington. This species is among California’s most popular shellfish and is one of the largest edible crabs along the Pacific Coast of America. The estimated maximum life span is from 8 to 13 years. Geographical range and

Hermit crabs are marine crabs of the family Paguridae, the most common being Pagurus bernhardus, and are found off of the coast of Europe and the Americas (“Hermit Crabs”). There are two main families of hermit crabs: marine hermit crabs and land hermit crabs. Marine hermit crabs mostly live underwater in various depths of saltwater, while land hermit crabs mostly live on land, but can also survive under water. Land hermit crabs are found in tropical areas, more specifically those of the Indo-Pacific

good pets out hermit crabs, according to Lianne McLeod, writing for The Spruce. Hermit crabs have small and soft abdomens that they protect by living in empty snail shells. As they grow bigger, they must look for bigger shells, and owners of these pets must progressively look for larger shells. The two main species of hermit crabs found in the US are the Coenobita clypeatus, commonly named as the Caribbean crab, purple pincher crab, land hermit crab, tree crab or soldier crab and the Coenobita compressus

Horseshoe crabs (limulidae) play a major role in our ecosystem, health studies and basic lives; which is why there are many ongoing conservation programs for this species and the bays where they come ashore to lay their eggs. Horseshoe crabs play a major role in the ecosystem by providing numerous other animals with food, many of which are migratory birds or sharks. these crabs spawn on Delaware beaches during the spring full moons, with the largest spawning site being the Inland Bays

Horseshoe crabs are marine living fossils, probably traced back to 485 million years ago. There are two horseshoe crab species found in Hong Kong. Horseshoe crabs are an ancient marine chelicerates, identified as the Class Merostomata and Order Xiphosura. The animals are identified by the having appendages around their middle of the mouth and their swimming legs at their end of their body. They are in close linkage with trilobites and arachnids which are spiders and scorpions. Amazingly, they are

Banggai cardinalfish, Pterapogon kauderni Introduction: Ichthyologist Dr. Frederick Petrus Koumans he is the one who described the species and erected a new genus, Pterapogon (cardinalfish with long fins), and assigned the species name of kauderni in honor of the Swedish zoologist Walter A. Kaudern who was the first to collect this species in 1920. It is among the relatively few marine fish to have been bred regularly in captivity, but significant numbers are still captured in the wild and it is

Female blue crabs lay 600,000-8 million eggs at one time. By definition, an ecosystem is all the living things and nonliving things that live in a specific area or environment and interact with each other. The Neritic Zone is located on the continental shelf. Much of sea life lives in this zone because it has well-oxygenated water, low water pressure, and a stable temperature. The Neritic zone goes down 200 meters or 656 feet. Like most animals, the blue crab’s ecosystem affects all the things in

The Atlantic Horseshoe Crab is an amazing a unique animal. Despite it 's name it not really a crab. It is actualy more colsly related to spiders, ticks and scorpians. It is in the Animalia kingdom and is in the Arthropoda phylum. It 's most common name is the Horseshoe Crab but it 's scientific name is Limulus polyphemus. The Horseshoe Crab is not just found in Cape Cod, it is also found along the northern Atlantic coast and up the Gulf of Mexico. The horseshoe crab looks very round, it also has

Horseshoe crabs are marine living fossils, probably traced back to 485 million years ago. There are two horseshoe crab species found in Hong Kong. Horseshoe crabs are an ancient marine chelicerates, identified as the Class Merostomata, Order Xiphosura. The animals are identified by the possession of appendages around their ventral mouth and their swimming legs at their distal end. They have closer lineages with trilobites and arachnids such as spiders and scorpions instead of the "real" crabs which
