Monotreme

species. The first name is the genus and the second name which follows the generic name and distinguished the species from others which are in the same genus (Swafford, 2016). Name have always been given to items such as plants, animals and fungi however Carolus Linnaeus was the scientist who came up with a hierarchal structure which shows its name as well as its phylogenetic name. Even though this classification system is set in place the name of a species can change and be re- evaluated due to phylogenetics and not phenetics (Science,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 complex and fast movements. The reason the Zaglossus bruijni falls under this kingdom is because it is an animal, therefore, it falls under the Animalia classification. (Myers, 2001) Phylum - Chordata A chordate is within the phylum classification, it includes humans and vertebrae however not all chordates are vertebrates. All species under the Chordata classification have the following: Pharyngeal Slits - a few slits/ openings in the pharynx and act as gills…

Platypus is an unusual animal that lay eggs, which also called menomtremes. There are only 5 menomtremes left exist and 4 of them are belong to echidna (Froden 2014). Platypus can be found in east side of Australia fresh water environment such as tropical fresh water lowlands or plateaus (Australian Museum 2014). Platypus are carnivores, they often feed small freshwater marine creatures and insects. Platypuses are nocturnal animal and they often hunt during twilight or night (Australian Museum…

Image seeing a mammal with a bill of a duck, the tail of a beaver and a fur like an otter. It might be hard to believe but actually this is a description of a platypus. These fascinating mammals have many unique characteristics that make them different from other animals these include their diet, their habitat and their defense meckisiam. Let's explore the platypus’s diet. The platypus spends 12 hours on an average day searching for food. A platypus is a carnivore so their diet consist of…

Monotremes have small hatchlings that rely on lactation milk as a nutritional source. Eutherians, the mammalian line that evolved placenta resulting in intrauterine development, have young that heavily rely on milk. The milk in Eutherians does not change through a young’s development and its composition is constant. Marsupials, in comparison to Monotremes and Eutharians, have one of the most complicated and specific lactation systems. Their milk is constantly changing in order to better cater to…

pharyngeal slits allow the water to escape when it enters the mouth when the animal is eating. In most land animals, including mammals, the slits are existent only during embryonic development. The post-anal tail elongation of the body that grows past the anus. The tail has skeletal elements and muscles to help with movement of marine animals. In land vertebrates the tail assists with balance, signalling and attracting the opposite sex. Mammals are split into three main groupings, monotreme,…

“Monotremes are the most primitive type of living mammal. They lay eggs and have a single opening (cloaca) for reproduction and elimination of wastes. The female shave no teets but provide milk directly through the skin to their young.”(Dictionary.com) The platypus and the echidna are the only monotremes known in the world. While they are both monotremes, they are both different in many ways. The platypus and the echidna are different by their physical characteristics, their lifestyles, and by…

Throughout the course of history, mammals have evolved attempting to adapt to their changing environments. Since the world is continuingly changing, mammals needed to also change their habits and adjust so that they may continue to thrive and live. Three exemplary mammals that adapted so that they could exploit aquatic environments are the Orcinus orca, a cetacean, more commonly known as the killer whale, the Trichechus inunguis, a Sirenia, more commonly called the Amazonian manatee, and finally…

have is a notochord which runs underneath the nerve and helps support it. They also have a dorsal nerve chord, this is a bunch of nerves that run from your organs and mussels connecting them into your brain. All of the phylum Chordata have a post-anal tail at some point in their life, humans have it as an embryo whereas the thylacine has it their whole life. Animal Diversity Web. (2016). Dasyuromorphia (dasyuroid marsupials and marsupial carnivores). [Online] Available at:…

Evidence from the differences in teeth structure has provided evidence for the differentiation of marsupial and placental mammals. Fossil records have a general consensus that with maturation, marsupial’s third premolars and post canine check teeth are the only teeth to be replaced. This feature is observed in fossils dating back 95-100 million years ago. The analysis of morphological evidence has established a stronger relationship between marsupials and placental mammals than monotremes…

the rest of western civilisation. It is not hard to understand why Australia is physically unique. How many countries or continents in the world has a koala, kangaroo, emu, platypus, wallaby or a kookaburra in their natural habitat, other than Australia ? None, there is no other continent that has all this Aussie icon other than Australia . Did you know that 80% of all flora, 71% of mammals and birds, 88% of reptile species and 94% of Amphibians in Australia are endemic. This is because most…
