Crustacean

The Mantis Shrimps are marine crustaceans of the Stomatopoda. The specific species I choose to focus on is Lysiosquillina maculate, or Zebra Mantis Shrimp. The Zebra Mantis Shrimp is the largest Mantis Shrimp in the world, growing up to a length of 40cm. Most members of the Stomatopod order share mostly similar characteristics, so some of what I will write about is not specific to just Lysiosquillina maculate, but most of the members of the order.Anatomy and PhysiologyThere are over 450 different

Brine shrimp are used as live food for aquatic life in aquariums. Brine shrimp are usually easy to hatch out, but water types may make a difference in their viability. This study is being conducted in order to see if there is any significant difference in the types of water used in hatching out brine shrimp eggs. In which type of water do brine shrimp eggs hatch best? By studying the different types of water that could be used and knowing which one provides a better hatch rate, a benefit will be

In “Consider the Lobster,” by Davide Foster Wallace, Wallace argues that preference is defined as something personal that relates to suffering. He presents the idea that preferences are not enough to make moral decisions. The author begins this essay by describing the Maine Lobster Festival and all its festivities, followed by what a lobster is and its anatomy, and concludes with whether or not they feel pain through their suffering. Wallace does this to convey the message that lobsters are living

have been used when the manta was smaller and would need to defend itself against predators. As the mantas became larger in the open ocean, they no longer needed to defend themselves with the sting. Today, mantas have a cartilage stump as a tail where the sting would be connected to. Like all animals, mantas have several predators. Sharks, as well as false killer whales and orcas have been known to eat manta rays. Shark bites are seen in all populations of manta rays, but these bites are quite often

Now that we have covered what exactly an arthropod is and why they (specifically the uniramians class) are so successful, we can focus on one specific organism and look deeper into how they evolved to be so successful in the environment they are in today. The organism that we are going to be focusing on is the dragonfly. The dragonfly has been around for 300 million years and has manage to stay alive and thrive in its environments. Back then an ancestor of dragonflies roamed the planet, its name

Introduction: “Limulus polyphemus, the horseshoe crab, inhabits shallow-brackish marine environments ranging from the Atlantic Ocean along the North American coastline to the Gulf coasts of the United states and from the East coast of Mexico to the Yucatan Peninsula” (Walls, Elizabeth). There are three other species of the horseshoe crab worldwide: Tachypleus tridentatus, Tachypleus gigas, and Carconoscorpinus rotundicauda that closely resemble Limulus in structure and habits, ranging from the

Iodized table salt: This is the most type of salt used in homes and kitchens. It is called “Iodized” because today, most salt manufacturers fortify the salt with mineral Iodine. It is an essential mineral for fighting off certain Iodine-related diseases like hypothyroidism. There’s also another natural way to get this important mineral into someone’s system by eating more seaweed, which is rich in Iodine. Sea Salt: Made from evaporated water in the sea. Their are larger and coarser crystals of salt

There are differences between a hydra and a grasshopper; that all begins with how they digest their food intake. In one thing they are similar and that is how they have an extracellular digestion. When an animal has an extracellular digestion means that “the breakdown of food in compartments that are continuous with the outside of the animal’s body” (Reese 899). Examples of an extracellular digestion is when an animal has a gastrovascular cavity or a alimentary canal. First, a hydra is a predatory

A Manta Ray is a large devil ray that occurs in all tropical seas . It is seen leaping high out of the water . There 2 types of Manta Rays ; the Reef Manta (Manta Alfredi) and the Giant Manta Ray (Manta Birostris) . The largest species is the Giant Manta Ray , obviously ,it measures up to 9 meters long . Manta Rays eat zooplankton . Manta Rays have the largest brain of all fish . It has gills in the lower body which contains oxygen from the water . Manta Rays avoid contact with humans .

A lobster species that has been given up as dead has returned from the dead. Entomologists and conservation biologist who performed a new genetic analysis confirmed that the Lord Howe stick insect (Dryococelus australis) is alive. Science News reported that the DNA of the Ball Pyramid stick insect with museum specimens from Lord Howe suggested the two insects belong to the same species. The walking sticks were believed to have been wiped out when black rats were introduced in the 1920s to the Lord
