Transcript of Duck-Billed Playtpus

The Platypus needs various things to survive, such as food, water, shelter and oxygen.
Basic Needs
Duck-Billed Platypus
The platypus is an carnivore, which means that it eats animals. It mainly eats non-insect arthropods, and most mollusks. But they also eat other small fishes, fish eggs, worms either aquatic or marine, and aquatic crustaceans.
The platypus gets oxygen through the bill. The platypus has two nostrils on the top side of the bill, which it closes when entering the water. The platypus can hold its breath for up to 14 minutes, with help from the high levels of haemoglobin and red blood cells in their blood. They also lower their heart rate to preserve oxygen in their lungs (from 200 bpm to less than 10 bpm).
The platypus has a lot of contact with both biotic and abioic components of nature. That includes prey, predator, and others that share their habitat with the platypus.
Environmental Relationships & Interactions
The platypus has interactions with its prey, of course. When it dives underwater to hunt prey, they close all the natural openings. They instead use their bill to locate the prey. That's its sixth sense. Its bill can detect the faint electric pulses created by the prey's movements. Then the platypus follows the signal and snaps up its prey.
A lot of organisms share a habitat with the platypus, such as river and lake bacteria, fish such as carps, river and lake plants, and many more.
By Roy Huang and Jacob Park
The Platypus is a very unique creature with characteristics of a mammal, a reptile, and a bird. It has unique adaptation all the way from venomous spurs, to electroreception.
Adaptations For Survival
The platypus has a very good burrowing ability, thanks to its strong claws. The strong claws are used to help it make homes and burrow holes for the eggs to be laid in. It also makes nests to raise their young separately.
The male platypus has a poisonous spur on it's rear thighs. They use it to defend themselves, hunt prey, and fighting during mating season for females. The venom is powerful to kill small animals like dogs, but not life threatening to humans.
The platypus is capable of laying eggs, which is what it's famous for. This would be a reptile-like characteristic. Some other evidence show that primitive mammals all lay eggs, but later, they evolved into delivering their baby. The platypus however, kept the unique feature and became renown for it.
That's Me!!!!!
Roy is awesome and epic
It is pretty easy for platypus to get water because they live in it.
The platypus lives in rivers, lagoons, and streams around mountain regions. They live around the eastern shoreline of Australia, the state of Tasmania, and Kangaroo Island. They prefer to build their homes where there are steep banks that contain roots, overhanging vegetation, reeds, and logs. They prefer waters that are usually less than 5 meters in depth, although they have been found in aquatic areas above 1000 meters in elevation.

The platypus lives in the water, so it has contact with it, and is essential for survival. It also has contact with sunlight, which is essential to almost every living organism. It breathes in oxygen through its bill, and has contact with gravel, stone, sand, and pebbles.
The Platypus, or more specifically, the duck-billed platypus is one of the most primitive animals still living today. They are a very unique type of mammal that lays eggs (Monotreme). They have a unique DNA sequence that indicates they are a mix of mammal, reptile, and bird. During this presentation, you will learn about the platypus's basic needs, environmental relationships, adaptations, and interdependence!!!
Predators like foxes (Vulpus vulpus), dogs (Canis lupus familiaris), dingos (Canis lupus dingo), large snakes (Serpentes), birds of prey (Falconiformes), feral cats (Felis silvestris), eels (Anguilliformes), and humans (Homo sapiens sapiens) hunt down the platypus.
The platypus's most recognized part is probably the duck-like bill. The nostrils are located on top of the bill, and the platypus can sense the movements (electroreception) of their preys with its bill, then snatches them up. The bill however, doesn't represent a bird just because of the shape. Research shows that it is evolved independently, and the fact it is similar to a duck's bill is purely coincidental.
The platypus's tail is very flat, and fat. Its flat tail assists swimming in water, enabling it to steer very well in the river currents, like a rudder. It is also like a fat storage, especially important for the females because they spend a lot of time nesting in their burrow.
The platypus have webbed feet to help them swim more efficiently, and move around soft, muddy surfaces fast. Its front feet are fully webbed, like a ducks, but the back feet are only partially webbed. This is because it uses its front feet to swim, while the back feet, like the tail, is used for steering.
The biggest human threat to the platypus is water pollution. Humans used to hunt them for their fur. The most dangerous threats to platypus are when they accidentally get captured in poacher's fishing nets, the nets will strangle them to death. Also, dams and irrigation projects will destroy the homes of platypuses. The platypus population in New South Wales, Murrumbidgee River, and Victoria have been decreasing from the above reasons.
