What are the major phyla of kingdom Animalia?
There are nine phyla in kingdom Animalia: Poriferans are the most basic and comprise the sea sponges. Cnidarians are jellyfish and hydras which have a more complex system for hunting prey. Platyhelminthes are flatworms that are known for their regeneration abilities.
What two major phyla are animals classified?
Primitive phyla without a true coelom include the Porifera and Coelenterata (Cnidaria). Animal phyla are classified according to certain criteria, including the type of coelom, symmetry, body plan, and presence of segmentation.
What are the phylum of the animal kingdom?
Phylum. The animal kingdom is divided into 40 smaller groups, known as phylum. Here, animals are grouped by their main features. Animals usually fall into one of five different phylum which are Cnidaria (invertebrates), Chordata (vertebrates), Arthropods, Molluscs and Echinoderms.
What’s the largest group of mammals?
These three groups are monotremes, marsupials, and the largest group, placental mammals.
What two groups of animals are warm blooded?
Fish, amphibians, and reptiles are the others. Only two of these five groups are endothermic– animals that can control their body temperature. They are birds and mammals.
What are the two main groups of animals?
Because there are so many different types of animals in the world biologists have sorted them into groups. This is called classifying. The two main groups of animals are vertebrates and invertebrates. Vertebrates are all animals with a backbone.
Which phylum has highest number of species?
|Phylum||Common Name(s)||Number of Species|

What is the largest phylum of invertebrates?
The largest animal phylum is also included within invertebrates: the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages.
Which major phylum has Pseudocoelom?
The acoelomate phyla are Placozoa , Porifera , Cnidaria , Ctenophora , Platyhelminthes, Mesozoa, Nemertina, Gnathostomulida. Pseudocoelomate animals have a pseudocoelom. They have a body cavity but it is not lined with mesodermal cells.
Which is the smallest phylum in animal kingdom?
Placozoa is the smallest phylum in the animal kingdon with only one identified species.
Which animal phylum has only cellular grade of Organisation?

The largest division (or phylum) of the animal kingdom is Arthropoda, the arthropods. Arthropoda makes up 75% of all known animal species.
What is the oldest phylum?
The answer to the question of whether the sponges or the comb jellies (also known as sea gooseberries) represent the oldest extant animal phylum is of crucial importance to our understanding of organismic evolution.
What are the 7 classifications of animals?
There are seven major levels of classification: Kingdom, Phylum, Class, Order, Family, Genus, and Species. The two main kingdoms we think about are plants and animals. Scientists also list four other kingdoms including bacteria, archaebacteria, fungi, and protozoa.

What 2 groups of vertebrates are warm blooded?
WARM BLOODED VERTEBRATES. Birds and mammals are two classes of vertebrates that are said to be warm blooded. They possess various mechanisms to ensure that their body temperature is fairly constant, (unaffected by, and usually warmer than, their surroundings), so that they can function more efficiently and reliably.
Is Ostrich warm blooded?
Reptiles are cold-blooded and breathe with lungs. Dinosaurs were reptiles, although some scientists believe that some were warm blooded. Birds are warm-blooded animals with feathers and wings. They lay eggs, and most can fly (although many, including penguins and ostriches, cannot).
What are the major animal groups?
Invertebrate. There are many living things in the world. To keep them simple and easier to remember, the scientists had identify many groups of animals. The six main groups are: invertebrates, mammals, birds, amphibians, reptiles and fish.
