Chondrichthyes vs Arthropod The black widow is most easily recognized by the hourglass marking on the underside of its abdomen. When bitten, a neurotoxin is released that can cause dull pain and cramping in muscles, that can be accompanied by sweating and vomiting. Less than 1% of black widow bites result in death. Black widow spiders are usually not aggressive. If disturbed, they will retreat to a corner of their web. These spiders are more aggressive if they are protecting an egg sac. The
is major difference in aquatic respiration versus land reparation in vertebrates. In osteichthyes (bony fish), the largest group of modern fish, counter current flow is required for the most efficient form of gas exchange and respiration when chondrichthyes (cartilaginous fish) use ram ventilation. Fish in general require a more efficient form of gas exchange then mammals because their medium, water, contains less than 1% dissolved oxygen compared to 2... ... middle of paper ... ...stems in mammals
member of many diverse taxonomic groups, including Chordata and Chondrichthyes. These groups have many defining characteristics, which the Swell Shark displays all of. Lastly, despite the Swell Shark being of Least Concern in terms of conservation, it is still important to protect this species. The Swell Shark’s taxonomy is as follows: it is a member of the domain Eukarya, the kingdom Animalia, the phylum Chordata, the class Chondrichthyes, the order Carcharhiniformes, the family Scylorhinidae, and the
Similarly, another way fishing effects biodiversity and marine ecosystem function is being effected in-directly through possible fishing of species holding ecosystem engineer traits. So through increasing fishing pressures and the loss of particular fish species through disturbance, or bycatch that could be a possible ecosystem engineers, loss of such species can cause serious disturbance and influence both biodiversity and ecosystem function at a much faster rate (Coleman and Williams, 2002). Little
Fish is a common name given to a selected group of vertebrates. The origin of fish has many different viewpoints. The only thing we are sure of is that prokaryotes were here on earth first. This leads us to the hypothesis that all organisms are more elaborate versions of each other and prokaryotic organisms. Fish are known to be the stepping stone for all tetrapods (all vertebrates that walk on land) and are also considered the first known vertebrates. Fish are ever-changing creatures over the past
Dichotomous Key Prior to evolutionary theory, scientists relied on similarity of physical characteristics to classify organisms. An 18th century naturalist, Carolus Linneas, developed a taxonomic classification system. This hierarchical system divides organisms into 5 kingdoms. Organisms visible to the unaided human eye fall into the plant, animal, or fungi kingdom. Kingdoms are then divided into phylum. This division is based body type and skeletal organization. Phylum are then divided
there are still new sharks being recognized every day. Atelomycterus marmoratus, also known as the coral catshark, is a member of the scyliorhinidae family, which is the largest shark family. The coral catshark belongs to the animalia kingdom, chondrichthyes class, elasmobranchii subclass, and the A. marmoratus species. Another common name for the coral catshark is the marbled catshark, which came from the original name, Scyllium Marmoratum. (Marmoratum being Latin for marbled) The life of the coral
Electroreception is the process of locating prey by detecting weak electrical signals in the water produced by organisms. Chondrichthyes use this system to locate nearby potential prey, and it is assumed lampreys do the same (Bodznick and Northcutt, 1981). Electrophysical responses can be sensed in lampreys in the dorsal medulla, a portion of their brain (Bodznick and Northcutt
1. Give a brief overview of the evolution of fish. Fish were amongst the first known chordates about 500 million years ago. Therefore, they have a very elaborate and complicated evolutionary history. The first type of fish to appear during the Ordovician era were called Ostracoderms. They had their head and flanks covered with a bony armor while they had a cartilaginous back. The shield was used to keep off predators. The extinction of the Ostracoderms during the Devonian period saw the emergence
shark as a navigational aid through using the earth’s magnetic force (Rowat 2012). Evolution Studying the evolutionary history and adaption for this species is difficult and an ongoing struggle for scientists. It is classified in the order of Chondrichthyes suborder Elasmobranchii and family of Rhincodontidea. The difficulty in tracing this species evolutionary history stems from the fact that its ancestry dates back 245 million year ago to the Jurassic and Cretaceous
Shark, also known as a Carcharias taurus is from the Odontaspididae family and is a species of fish that is critically endangered around Australia. Kingdom: Animalia Phylum: Chordata Class: Chondrichthyes Order: Lamniformes Family: Odontaspididae Conservation Status The Grey Nurse shark has a current conservation status of endangered in Queensland and critically endangered throughout all
by a lack of oxygenated blood flow that the heart can receive and will die if they exercise too hard because the heart simply won’t receive enough oxygen to sustain intense exercise. In order to solve this problem many species of teleosts and chondrichthyes possess adaptations that allow them to continue exercising at extremely high speeds without necessarily dying. Tunas, for example, are pelagic thunniform swimmers that have evolved these special adaptations that allow them to maintain high cruising
The Kingdom, Phylum, Class, Order, Family, Genus and species for the Bull Shark are as follows: Animalia, Chordata, Chondrichthyes, Carcharhiniformes, Carcharhinidae leucas (Simpfender & Burgess). The taxonomy of every living thing is different, so the classification of the Bull Shark is the one way worldwide to know exactly what animal is being referred to because one animal may have many different common names. Carcharhinus leucas is referred to by many different common names around the world for

Migration Migration is the movements or travels made by animals to locations outside of their natural environment for an extended period of time (Dingle 2007). Typically when migrating, animals are searching for a sustainable location with many of the resources needed available. Some animals migrate back and forth between the same areas while others avoid returning to the same area. A rule of thumb when discussing where animals migrate is by looking at the animal’s life span. Animals with a longer
Scaly, Salty, Seine in the Big Old Blue Salty dihydrogen monoxide, known as the ocean contains many species of osteichthyes, chondrichthyes, and agnathans. Or in laymen’s terms, fish. These animals are threatened by the world today for one main reason, humans. We have done the undesirable, but for probable cause. We have created a market for workers to earn money by fishing, bringing in tons of fish to be sold to the public, and have gotten rid of dangerous wild animals in the oceans so people
business long before dinosaurs walked the world. The fact that sharks have survived thus far without changing very much is a long real tribute to the effectiveness of their anatomy. Sharks are fishes, confined within the taxonomic class called Chondrichthyes (meaning "cartilage-fish"). Sharks besides other cartilaginous fishes (rays, skates, and rat fishes) differ from the skeletal fishes because sharks have a cartilaginous skeleton, and lack a swim bladder. Worldwide there are over six hundred different
The Great Barrier Reef What is the Great Barrier Reef? The Great Barrier Reef is a huge, colourful and bright coral reef, situated off the coast of Queensland in the Coral Sea. It is so big that it is the only living thing that can be seen from Space! It consists of over 2,900 individual reefs and 900 islands that stretch over 348,700 km². It is in a wet, tropical climate with reasonably warm Winters and a high humidity in the Summer. Water temperatures span from 14 degrees Celsius in the Winter
The history of taxonomy dates all the way back to the 4th century, where organisms were divided into 2 groups, plants and animals by a Greek philosopher, Aristotle. Early naturalists did not acknowledge that the similarities and differences between the two organisms were results of evolutionary means. So as the years went on, classification gradually changed and slowly became more and more sophisticated. In 1758, Carlos Linnaeus established the first major break through with classification, and
