damage DNA because of a highly efficient DNA repair system. Although they are considered Gram-positive, they may be an intermediate between gram-positive and gram-negative bacteria and form a distinct bacterial lineage of extremophiles; the Firmicutes phylum has a diversity of microbes associated with the human gastrointestinal tract, especially with fatty acids absorption which makes it connected with obesity when a change in the microbiome occurs, and dominate the bowel environment being…

The Chordata is the third largest phylum in the kingdom Animalia. Chordates are bilaterally symmetrical; meaning one half of their body is a reflection of the other half. The Chordata phylum has several general characteristics unique to only this organization of creatures. The first is pharyngeal slits, which are openings behind the head that connect to the throat. These are known as gills in some chordates. Humans have these in the womb but eventually form into the inner ear. The second feature…

The Maritigrella crozierae, or the Tiger Flatworm, is a free-living flatworm that is a part of the Platyhelminthes Phylum. Its full taxonomic classification from kingdom to species is, in order: Animallia, Platyhelminthes, Turbellaria, Polychladida, Eurylephidae, Maritigrella, and Crozieri. Tiger Flatworms live in Saltwater. The areas they typically inhabit are the islands around the Caribbean and the Bermuda. These flatworms feed on orange tunicates, a sessile marine invertebrate that has a…

Chordates, which is the phylum or classification of fish and mammals of the sea, are the most developed marine organisms. Scientists believe that Chordates originated about 590 million years ago. The original organisms of the Chordata phylum are believed to have lacked skeletal structures, and therefore, left a very undetermined fossil record. The vertebrate fossil record begins approximately 400 million years ago. Early Chordates were tunicates, marine organisms that would frequently form…

heterotrophs and depend on autotrophies. Krill are shrimp-like marine invertebrate animals. These are smaller zooplankton but it is important for larger marine mammals as food for baleen whales, whale sharks, seals, and a few seabird species. Krill phylum is Arthropod. Krill form key trophic link between primary producer and higher level in marine food web worldwide. The size range of krill is about two inches (five centimeters) in length. Microorganism like diatoms etc when colonize on…

speciation is not confirmed, but it could be because of different geographical regions. Some common traits between them is their slender bodies, they all feed on insects, and they all have fluffy tails. Narrow Striped Mongoose: Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Eupleridae Genus: Mungotictis Species: Mungotictis Decemileata The Narrow Striped Mongoose lives in South Western Madagascar. They only have about 500 square kilometers in habitat area. It is…

Taxonomy in biology is the study of naming, describing, and classifying new organisms into different branches, Domain, kingdom, phylum, class, order, family, genus, and species. Throughout history, humans have always classified organisms that they have encountered. One of the first taxonomists was Aristotle, “who organized five hundred types of animals according to habitat and body form” (http://www.biologyreference.com). However, the first modern taxonomist was Swedish botanist Carl Linnaeus,…

Blue poison dart frogs are very interesting animals. They are interesting because they are the most poisonous type of frogs. The animal I chose is the blue poison dart frog also known as the Azureus. The phylum it belongs to is Chordata. Characteristics of the Chordata phylum are: most have vertebrates in other words animals with a backbone, they live in water for part of their life, they have no notochord or a skeletal rod, they have a nerve cord, and slits in their throat. For…

water. The body of the oxytricha was filled with spots and contained two outlines of a circle which were the macronucleus and micronucleus. The characteristics of the oxytricha were expected from observation since it is similar to other species of the phylum and other…

Chordata is a phylum of the animal kingdom that includes animals possessing notochord, pharyngeal gill slit and dorsal tubular nerve cord. Although the name Chordata is attributed to William Bateson (1885), it was already prevalent around 1880. Phylum Chordata, though not the largest, is the most diverse phylum in the animal kingdom. Chordates are cosmopolitan and are well represented in marine, freshwater as well as terrestrial habitats from the equator to the high northern and southern…
