Are Amphibians Ectothermic Or Endothermic

Basic Types of Animals and Their Characteristics

Scientists sort the dissimilar types of animals in the earth into categories based on certain characteristics. Animals are generally grouped into half dozen types of animals. The system for animal classifications is called taxonomy.

The Animal Kingdom

All animals vest to a biological kingdom called kingdom Animalia. This kingdom is then broken downwardly into over 30 groups, or phyla (plural form of phylum). Almost 75% of all species on Earth are animals. Animals are and so cleaved down into two types: vertebrates and invertebrates.

Animals with a backbone are vertebrates.
Vertebrates vest to the phylum called Phylum Chordata.
Vertebrates are further broken downward into five classes: amphibians, birds, fish, mammals, and reptiles.
Animals without a backbone are invertebrates.
Most invertebrates are in the phylum Arthropoda.

All Almost Amphibians

All amphibians are vertebrates, and they need moist environments or h2o to survive.

They are cold-blooded.
They absorb h2o and breathe through their thin skin.
They have at least one special skin gland used for defense.
Virtually follow the life bike of egg-larva-adult.

Examples of Amphibians

You tin notice examples of amphibians all around the world. In some cases, examples of amphibians seem similar the aforementioned animals, just they can be quite different like a frog and a toad.

frogs
newts
salamanders
toads

All About Birds

Birds are a type of warm-blooded vertebrate that are adapted to fly.

Not all birds can fly, but they practise all have wings.
Birds have beaks that help them catch and eat food.
The digestive system of a bird allows it to consume whenever it tin can and digest the food later.
Birds lay eggs to reproduce.
They are endothermic, meaning they maintain their ain constant torso temperature.
They are bipedal, which means they have 2 legs.
They accept hollow bones and their bodies are covered in feathers.
Birds belong to the class called Aves.

Examples of Birds

Birds are some of the most recognizable animals, and you probably see unlike types of birds every day.

albatrosses
chickens
hummingbirds
falcons
flamingoes
ostriches
owls
parrots
penguins
pigeons

All About Fish

Fish are also vertebrates, and they are considered the oldest-known vertebrates.

They are ectothermic, or common cold-blooded, which means they rely on their surroundings to regulate their torso temperature.
Fish have fins.
Most, merely not all, fish have bodies covered in scales and exhale through gills.
Fish live underwater.

Examples of Fish

There are over 30,000 species of fish alive today, more than all other vertebrate groups combined.

eels
hagfish
lampreys
minnows
rays
salmon
seahorses
sharks

All Near Mammals

Mammals are another type of vertebrate that belong to the class Mammalia.

Young mammals get nourishment from milk produced by their mothers.
Most mammals have pilus.
Their jaw is hinged directly to their skull, unlike all other vertebrates.
Almost all mammals give nascence to live babies.
They are endothermic, or warm-blooded.

Examples of Mammals

There are over 5,500 living species of mammals all over the earth.

aardvarks
bats
elephants
hamsters
humans
rabbits
rhinoceroses
whales

All About Reptiles

Reptiles are thought to be the outset vertebrates to alive completely on land. Simply, not all reptiles live just on country today.

They are cold-blooded, or ectothermic.
They lay eggs to reproduce.
They have four legs or are descended from animals with four legs.
They breathe through lungs.
Their bodies are covered in scales or scutes.

Example of Reptiles

Different species of reptiles tin be tiny or huge.

crocodiles
geckos
lizards
bounding main turtles
snakes
tortoises
turtles

All About Invertebrates

Approximately 95% of all animals are invertebrates. Invertebrates do not have a backbone. At that place are different types of invertebrates, but they all share a few characteristics.

They are fabricated up of many cells that work together or are multicellular.
Most, but not all, have tissues, cells that work together in a more complex style.
About, but non all, can motility.
There are over 35 phyla of invertebrates.
They by and large accept soft bodies.

Types of Invertebrates

There are eight phyla of invertebrates that are alive today.

annelida - take a segmented torso and archaic brain
arthropoda - have jointed appendages and an exoskeleton
cnidaria - have tissues and an incomplete digestive system
echinodermata - have some type of spiny structure on their outside
mollusca - generally have soft bodies and a difficult exoskeleton
nematoda - unsegmented with worm-shaped bodies
platyhelminthes - soft, ribbon-like worms with no respiratory system
porifera - multicellular organisms living in water with no organs or tissues

Examples of Invertebrates

Most invertebrates are insects, simply there are over i million species of invertebrates in the world.

anemone (cnidaria)
clams (mollusca)
coral (cnidaria)
venereal (arthropoda)
earthworms (annelida)
flatworms (platyhelminthes)
insects (arthropoda)
jellyfish (cnidaria)
leeches (annelida)
roundworms (nematoda)
sea urchins (echinodermata)
snails (mollusca)
spiders (arthropoda)
sponges (porifera)
squid (mollusca)
starfish (echinodermata)
tapeworms (platyhelminthes)
