Arthropods are animals with tough exoskeletons, or outer shells made to protect their internal organs. Arthropods shed their exoskeleton and grow new ones as they develop and grow. Arthropods' bodies are segmented, meaning its divided into sections, they also have jointed legs. The three largest groups of arthropods are crustaceans, insects and arachnids. Crustaceans live on salt water or land. There are 50,000 species of crustaceans, and examples are crabs and shrimp. Insects are the largest group of arthropods, with over a million species! They are made of a head, thorax and abdomen. Three pairs of legs are attached to its thorax. They have antennae and eyes to help it sense and live in its environment. Examples include grasshoppers and ants. Arachnids include spiders and ticks. They have appendages, 4 pairs to be exact. And they are divided into one or two body sections, depending on the species of arachnid. All arachnids are able to produce strong silk fiber, that's what spiders use to catch prey.
Fun facts about arthropods:
1. Ancestral arthropods were the first animals to ever live on land!
2. The oldest species of arthropods are Pneumodesmus newmani, a species of millipede.
3. All arthropods go through metamorphosis.
4. Infected mosquitos are the most common type of arthropods that spread disease, disgusting!

Sponges are members of phylum
They are multicellular
Kingdom :Animalia
All most all sponges are found under water and deep sea environments but they always live attached to the sea floor.

Some Mollusks live on land, and some live in water.

cnidarians are members of phylum and they are mostly marine animals. https://www.britannica.com/animal/cnidarian it has over 11,000 species, specialized cells and their body consists of mesoglea, a non jelly-like substance. There are 2 types of cnidarians: polypoid and medusoid. polypoids have tentacles and a mouth that face up, meducoid have tentacles and mouth face down. https://www.thoughtco.com/cnidaria-phylum-profile-2291823

They have bilateral symmetry, (Bilateral Symmetry is symmetry that is equally divided).

Echinoderms live in the ocean they are found at every level in the ocean from the intertidal zone to the abyssal zone that is deep! They have spiny skin their skeleton is protected by the epidermis and is still an exoskeleton echinoderms move slowly. Almost all echinoderms can regenerate limbs!
scientific name of echinoderms is Echinodermata. most echinoderms can reproduce asexually by losing limbs and those limbs turn into another echinoderm! Sexually involves the external fertilization by spermatozoa the fertilized eggs develop into platonic larvae. echinoderms Have No Blood.
echinoderms Have Tiny Feet All Over Their Arms.
echinoderms Are Predators!
Sea Stars Have Eyes- Or at least eyespots
Sea Cucumbers Can Puke Their Guts Out- Literally!

People Eat Sea Urchins.
If You Put A Sea Cucumber In Fresh Water It Will Explode.
Their Name Literally Means "Spiny Skinned.
starfish grip their prey then they slowly pry apart the shells the sea star will then eject its stomach through its mouth and inside the shells.
When sea cucumbers are threatened or scared by a predator, they can violently fling their internal organs at their attacker, often causing the predator to become confused and leave. Another handy skill they have is regrowing lost organs.echinoderms are considered the most complex invertebrates. some echinoderms would eat other smaller echinoderms! Examples of echinoderms: starfish, sea urchin and sea cucumbers are some
examples of echinoderms .

Cnidrians include jelly fish and corals they have stinging cells that they use to capture fish and other organisims hydras and sea anemones arre also cnidarians

Cnidarians are a phylum of animals of true dimensions. It contains about 10,000 species of relatively simple animals that are often found in aquatic, often marine environments. It takes its name from the stinging cells and they are distinct cells that carry stinging organell   
The 4 classes of cnidarians 
Anthozoa, which includes true corals
Cubozoa, the amazing box jellies with complex eyes
Hydrozoa, the most diverse group with siphonophores

Scyphozoa, the true jellyfish.

They have soft bodies; (Soft body means they lacks skeletons)

Flat Worms and round worms live in water, in damp soil, or inside other animals. They have simple structures. Segmented worms, unlike flatworms and roundworms, have bodies that are divided into compartments. Most segmented worms, including earthworms, live in damp soil. A few, such as leeches, can live in water.

Omar al askari

flatworms live in water in damp soil or inside other animals and have ribbon- like bodies and there are over 20000 flatworms

round worms which have a body cavity but no segments and they live in water in damp soil or inside animals and there is 40000 and they can live inside the small intestine for 2 years in side your body. in most cases roundworms can be easily treated by taking medicine

segmented worms which have both a body cavity add segmented bodies and they live in damp soil a few such as leeches can live in water and most infection aren't serious and can be treated with medicine.

EXAMPLES

Crabs, Shrimp, spiders, Ants, Beetles, silverfish, cicadas, ticks, scorpions, Krill, lobsters, Barnacles,
Grasshoppers, centipede, Praying mantis, Termites, Walking sticks, Stink bugs, Dragonflies, Black widow spider, Brown recluse, Chiggers, Crab spiders, Mites, Whip tailed scorpions, Wind scorpions and Seed shrimp. with all these examples I hope you will have a idea what Arthropods look like.

Worms are all symetrical which means that both sides are exactly the same.Flat worms and roundworms live in water, in damp soil or inside other animals. Segmented worms have bodies that are divided into compartments.

an arthropod is an invertebrate animal having an exosekeleton a segmented body and paired jointed appendeges arthropods in our homes Hexapoda: Insects. The largest group within the arthropod phylum, Hexapoda is derived from Greek meaning animal species

Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the common ancestor of all animals, making them the sister group of all other animals. Sponges belong to a phylum called Porifera. They come in many different colors. Sponges attach themselves to the ocean floor and filter small food particles from the water.

Fun Facts :

1. Early fossil records show that sponges inhabited Earth around 600 million years ago. That is a mighty long time for an animal without a complex nervous, digestive, or circulatory system!

2. Some deep-water sponges can live to be over 200 years old.

3. Sponges are master filters.

Cnidarians lives in the oceans

Most cnidarians prey on organisms ranging in size from plankton to animals several times larger than

Cnidarians are carnivores, and some can also consume plant

themselves

Adam Yousef

2020-10-22 05:59:53 UTC

The phylum Cnidaria is a diverse group with cosmopolitan distribution. It includes the familiar hydras, the transparent jelly fishes, the beautiful and bright coloured sea anemones, a variety of corals and about 10,000 delightful aquatic species.

how do cnidirians move ?

Adam yousef

2020-10-22 06:03:43 UTC

The cnidarians are almost all marine and are either sessile or free-swimming and occur singly or in colonies. They are characterised by the possession of radial symmetry (a primitive feature), two layers of cells, gut cavity lined by endoderm, vibratile tentacles arranged in one or more whorls around the mouth and provided with nematocysts (the stinging organ). They are the pioneer in the tissue grade of organisation.

Sponges are mostly not considered alive because it is many cells that grouped together over time. They are usually soft and have to backbone. Sponges are the filters of the oceans. It can filter out microbes.
