About Vertebrates Vertebrates are animals that have back bones. Vertebrates include reptiles, mammals, fish, birds and amphibians. video
Amphibians • Amphibians belongs to the kingdom of Amalia. • Amphibians are cold-blooded such as frogs, toads and salamanders • But the body of amphibians changes with the environment in cold weathers amphibians hibernate during the winter. • There are over 64300 thousand species of amphibians. • Frogs belong to the group of amphibian in the order of Anura. • . Frogs are cold blooded but when they get to warm they lay in the sun to warm up. • Some frog fossils were found by scientist almost over 140 million years ago. • . Frogs can be found near water but they mostly prefer ponds lakes and also marshes.
(continue) Amphibians Some adaptations • They have a small waist but no neck, flat skull because it’s easy for them to swim and hold its prey. • They have front legs and feet to use to keep the front body off the body or ground. Characteristics • They have moist, scale less skin that absorbs water and oxygen. Without the moist condition skin they will die, that’s why you’ll see lots of amphibians are near water. Many Amphibians eat meat and are carnivorous. But for most of them they eat insects and other invertebrates.
Birds • There are 8,600 different species of birds. • Birds have scaley legs and they have no teeth
What they eat • Some eat seeds, berries, fruit and insects. • Others eat small mammals, fish, larvae, aquatic vertebrates, and acorns
Habitats • Birds can live in jungles, parks anywhere where there are trees.
More information • They migrate during fall and winter. • There is a bird that can drunk, if it inhales alcohol. • Females don’t need to mate to lay eggs.
Fish • Fish are aquatic vertebrates. • At 31,000 different species, fish exhibit greater species diversity than any other vertebrates.
Adaptations • Fish are cold-blooded, allowing the body temperature to vary as the ambient temperatures change. • Not all fish have scales; the fish that don’t have scales have a thick layer of mucous. • The purposes for their scales are to give the protection. • . Their gills are used for breathing underwater.
How they move and their habitat • Their fins and tail help them swim. • Obviously, fish live in water. Fish can be found in most aquatic environments
What they eat • It actually depends what fish your dealing with. For fish in aquariums, they eat things like flakes, tablets and other fish food you buy at the stores. But for fish in the oceans, lakes etc, they eat plankton, dirt, algae, seaweed, fish that are smaller than them and mostly anything they can find to eat.
Mammals • Mammals are any animals that produces, feeds it young with milk, and is warm-blooded. • There are about 5400 species. • Some adaptations are for animals that live in cold climates have coats of fur or blubber to protect them from the cold. • Mammals have developed different adaptations for the different environment that they live in .
What Mammals eat • Mammal eat plants, meat, fish, and insects. • They can be carnivores, herbivores, and omnivores.
Habitats • Mammals can be found on land, in water and in the air. • They can be found all around the world.
Reptiles • All reptiles are cold blooded that’s why they warm themselves in the sun • There are 6,800 species of reptiles on earth • Most reptiles have dry, scales and, scutes • Scutes are bony external plates or scales • Turtles have scutes on their shells • And crocodiles have them on their skin • The kingdom Reptilia is the kingdom the reptiles belong to
Adaptation • Reptiles have thick skin that minimizes water loose to cool them selves (it especially works for reptiles if they are in the dessert) • In autumn reptiles lose their body heat because, the weather is cold, this helps them survive extreme weather
Reproduction and Information • Like most living things, reptiles have to find a mate in order to reproduce • Some reptiles lay eggs some give birth to live young • Many reptiles that live in hot climates are mostly active at night • A few lizards have long legs, so they can absorb less surface heat while running and just moving
Where they live and what the eat • Some live in the dessert • Some live in creeks • Some live throughout the warm and temperate regions • Most reptiles are carnivores which mean they eat other animals and insects • Only a very few reptiles are herbivores which mean the eat plants or berries
