Chordate

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 large colonies through asexual reproduction, a process of reproduction where an organism does not need a partner in order to achieve fertilization. Eventually, lancelets evolved from tunicates with a more developed brain, along with gills that opened…

2009) This means names of species names may change due to genetic information showing how close or how far apart certain species are. ( Science,2009). Kingdom Animalia Phylum Chordata Class Mammalia Order Monotremes Family Tachyglossidae Genus Zaglossus Kingdom - Animalia Every animal comes under the kingdom of Animalia which is also known as Metoza. The animal cells miss a wall which the plant cells have, In comparison to plants and organisms, animals have the ability to perform…

animal to the tail and is the major nerve cord of nerve fibers. The notochord is present in all chordate embryos and runs beneath the dorsal nerve cord, which is another key feature of chordates. Pharyngeal gill slits are the openings between the pharynx and the outside. They resemble gill slits and are on present for a short amount of time in the embryonic stages of the tetrapod development. Finally the post-anal tail which extends behind and above the anus. All chordates have a post-anal tail…

The notochord is the defining structure of the chordates, and has essential roles in vertebrate development. It is a flexible, rod-shaped structure that is in the embryonic stage of all chordates. It gives the skeletal support and is found in between the digestive tube and nerve cord. In some animal chordates lifetimes it is the main axial support in the body. The dorsal hollow nerve cord is the only feature unique to all chordates. It is located at the top of the animal, above the notochord.…

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…

Middle school is like a big, deep, blue ocean with a clown fish, a sunfish, a box jellyfish, a stone fish, a lionfish, a octopus, a turtle, a seahorse, a squid, a eel, a stingray, a sea cucumber , and a dolphin. The clownfish is Jacob because he is the class clown. The sunfish is Paige because sometimes if someone gets to close to her, she will bit. The box jellyfish is Kaleb because he is such a pain in the butt that he leaves scars wherever he goes. The stonefish is Cameron because he…

Species Taxonomy- The gharial is taxonomically classified under: Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Crocodylia Family: Gavialidae Genus: Gavialis Species: gangeticus The Indian gharial is also known as the gharial, fish-eating crocodile, Indian gavial, gavial, and long-nose crocodile. The name gharial is derived from the Hindi work “ghara” which means pot and refers to the bulb on the end of the crocodile’s snout. There are no taxonomic discrepancies…

This is a book report on the animal The Axolotl, which comes from Aztecs. Axolotl means water, while xolotl means monster. So this animal is considered a, “Water Monster.” It is a non-native fish that also goes by the name, “Mexican Walking Fish.” It’s an amphibian, like a frog, and is in a paused state of metamorphosis. Their classification is in the phylum, Chordata. The Axolotl was first founded in 1789, in Mexico City. The labs that they were founded in and tested on were in Paris. They are…

The african elephant lies in the phylum chordata because it has tissues, and a coelom. Along with having these two attributes, it is bilaterally symmetrical and also possesses a dorsal,tubular nerve cord and a postanal tail. It lies in the class Mammalia because it possess hair which is made of keratin, the hair provides insulation. It is endothermic (the majority of the heat energy is used to maintain their high body temperature). It has a 4 chamber heart. They also have mammary glands that are…
