Chondrichthyes

classes, which thusly contain orders and families, genus and species. Each organism is allotted two names. The first name would be the organism’s genus, and the second name would be its species. Taxonomy consists of all of these groups, as it is affiliated with classifying every organism on this planet. Taxonomy of Great White Sharks (with definitions of each classification) Common Name: great white shark Kingdom: Animalia. Essentially all animals that have ever existed fall under Animalia. Phylum: Chordata. Organisms that have at least at some stage of development a notochord (a supportive rod-like structure made from cartilage), a central nervous system located in the back, and openings for water to pass over the gills. Class: Chondrichthyes. Jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage (rather than bone). Order: Lamniformes. Includes all (and only) mackeral sharks; sharks having a pointed snout with large teeth and a crescent-shaped tail. In addition, an anal fin, five-gill slits, two dorsal fins, no fin spines, mouth behind the eyes, and no nictitating eyelids. Family: Lamnidae (very similar classification to lamniformes). This family includes mackerel sharks, porbeagles (large Atlantic sharks), and great white sharks. Genus Species (aka scientific name): Carcharodon carcharias Great white sharks are notorious for being the ocean’s top predator and they are incredibly feared by humans. They are feared…

Phylogeny of Sphyrna- Hammerhead Sharks INTRODUCTION I will be investigating the phylogenetic history of Sphyrna, a genus of hammerhead sharks. The eight species that fall under this genus are Sphyrna corona (scalloped bonnethead), Sphyrna gilberti (Carolina hammerhead), Sphyrna lewini (scalloped hammerhead), Sphyrna media (scoophead), Sphyrna mokarran (great hammerhead), Sphyrna tiburo (bonnethead), Sphyrna tudes (smalleye hammerhead), and Sphyrna zygaena (smooth hammerhead). Hammerhead sharks…

We’ll be back soon okay?” Cable said. “If you need the gun, it’s under the blanket.” I nodded. He climbed up the ladder that led to the deck. I walked to the blanket and lifted it up. A flare gun was resting under the blanket. “Well hopefully I won’t need it!” I shouted to Cable. Cable chuckled. “I hope not.” Cable zipped up his bag and threw it onto his shoulder. I lifted the blanket up and set the gun inside gently. I sighed. I dropped the blanket on top of the gun. I climbed up the ladder…

The Greenland Shark can live for over 200 years, it can also grow up too 15 feet which is the size of a School Bus. Although the population of the Greenland shark is low it is not yet known if it yet a endangered species. Most greenland shark and actually as blind as a bat because there are parasites living in the eyes called ommatokoita which are permanently attached to the edges of there eyes. These parasites are usually about 30mm long, although these parasites make them blind it also helps…

There are many different types of feeding mechanisms in the class Chondrichthyes. Feeding mechanisms have evolved as the some of the earliest species in the Chondrichthyes class was known for having long jaws that were attached to the skull. The previous methods of feeding for these species from before would’ve caused minimal damage. The evolution of the feeding mechanisms in this class opened a variety of dietary options for these water-bound creatures. Hence the diversity of feeding mechanisms…

Classification – Chondrichthyes is a class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. The kingdom of a grey nurse shark is Animalia because the grey nurse shark is a multicellular animal. The phylum is Chordata because it is a large animal that includes vertebrates . The class is Chondrichthyes because it has a cartilaginous skeleton. The order…

The Blacktip Reef Shark is native to the tropical coral reefs of the Indian and Pacific Oceans. The Blacktip is listed under kingdom animalia, phylum chordata, class Chondrichthyes, order Carcharhiniformes, family Carcharhinidae, and genus Carcharhinus. This shark was given its name based off of the blacktip at the end of its dorsal fin. This fin appears very vivid in the shark’s youth, but fades with age. The Blacktip Reef Shark will most likely grow to be 4.9 feet and weigh roughly 40 pounds,…

Introduction. Sharks have been around for hundreds of millions of years Subclass Elasmobranchii: Sharks and Rays are classified in the Kingdom Animalia, Phylum Chordata, Class Chondrichthyes(Greek, chondr- 'cartilage', ichthys 'fish'), and Class Elasmobranchii. Elasmobranchs are fish which all share one main characteristic: cartilaginous skeletons. There are over 1,000 species of elasmobranchs ranginging from great white sharks, to spotted rays to sawfish to skates. Sharks and rays are the…

organs and muscles of the body. The fourth feature is a post-anal tail. This is another feature that humans outgrow in the womb. The final feature of Chordates is that their blood is contained in vessels. Calculating an exact number of organisms classified under one category is impossible because scientists cannot agree on the criteria used to classify each organism or one organism falls into multiple categories. There is an estimated 50,000 living species within the phylum Chordata that are…

the food chain but they are killed and eaten by humans and killer whales. The Great White Sharks scientific name/ species name is the Carcharodon Carcharias. The Great White Shark is dominant depending on size and sex. Females are normally larger, so they are dominant to male Great Whites. Female Great Whites are normally pregnant for 12-18 months and they give birth to 3-14 5 foot long, live pups at a time. The pups are immediately left to fend for themselves. The Great White shark pups are in…
