Annelid

about how their bodies operate because of how they are made up. I will give a brief synopsis of both animals before going into major detail about them. According to the online website named dictionary.com, it says that an earthworm is a burrowing annelid worm that lives in the soil. Earthworms play an important role in aerating and draining the soil and in burying organic matter (Dictionary). Crayfish are nocturnal freshwater crustacean that resembles a small lobster and inhabits in streams and rivers

globally. Without pollinators plant species would be more susceptible to extinction. In agricultural systems, invertebrate pollinators are responsible for the successful production of vegetables and fruits that maintain livestock production. Nematodes, annelids, and arthropods aid in decomposition (Prather et al., 2012) Materials and Methods: The experiment began with the construction of a Berlese funnel, which is an apparatus used to extract

Protostomes is the Annelida having trochophore larva (Figure 3), “a free-swimming top-shaped larva with two bands of cilia around its middle”. (Solomon et al., 2015) For aquatic annelids like tubeworms, the movement of cilia on its larva creates water current which helps in locomotion and feeding by bringing the food closer. Annelids then develop a tubular body that is segmented (Figure 4). In addition to trochophore larva, Mollusca have a veliger larva in its second larval stage. The veliger larva consists

Annotation: The purpose of this experiment was to observe the light that the Tomopteris emits. They collected Tomopteris from Monterey Bay off the coast of California. They then stimulated the Tomopteris to produce light so that they could observe the light that it produced. The researchers took photos and measured the amount

Organ Systems Project (Digestive, Excretory, Circulatory, Reproductive, Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia, one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus, are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

arthropods? The characteristics that contribute to the diversity and abundance of arthropods is the ability to adapt because of their rough, exterior skeleton and joint appendages. Is the circulatory system of arthropods more similar to that of annelids or of mollusks? Why? The circulatory system of arthropods is like mollusks because both have open circulatory system. How does growth in arthropods differ from growth in humans? Arthropods have an exoskeleton.

ANIMAL BIODIVERSITY Comparison among the following phylums: 1. Phylum Kinorhyncha 2. Phylum Priapulida 3. Phylum Nematomorpha 4. Phylum Loricifera Phylum is a taxonomic division on the base of different characters of all species present in biosphere. Species with similar characters are placed in a single phylum.These phyla have a large number of species but these species are very small in size. And moreover, all species of these phyla have not been fully studied. Here, the comparison of these phyla

Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with

Universal Statement: There are three phylum of worms. There are the flatworms (Platyhelminthes), roundworms (Nematoda), and the segmented worms (Annelida). Flatworms have long, flat bodies and are usually parasites. An example of one is the Planarian, which are free-living and feed like a vacuum cleaner. Roundworms have long, round bodies and unlike cnidarians or flatworms, have a digestive system that is like a tube, open at both ends. Segmented worms have long, round bodies made up of linked segments

General Appearance: Earthworms have a body that is shaped cylindrical and usually varies from 90 to 900 millimeters when they are full grown. The outside of the worm is divided into segements that is called primay segmentation. This means that the worm is divided by the longitudinal axis which is seperated by the septa and furrows. The Lumbricus species have an advantage when they are trying to tunnel and during locomotion by having retractile structures. Having these structures the species is able
