Answer:

Poriferan/Sponge:

-They are filter feeders that live in aquatic environments

-Their body is made up of a porous skeleton made of spongin or silica

-They do not have true tissues or organs

-They reproduce sexually or asexually through the process of budding

-They are considered to be some of the oldest animals on Earth

Cniderians/Coelenterata:

-They are aquatic animals that include jellyfish, coral, and sea anemones

-They have a simple body structure with two cell layers and a central gut

-They are radially symmetrical and do not have a head or specialized organs

-They are carnivorous and capture their prey with tentacles containing stinging cells

-They can reproduce sexually or asexually through processes such as fragmentation and budding

Platyhelminthes/Flatworms:

-They are flattened worms that can be found in aquatic and terrestrial environments

-They have a simple body structure with a diffuse nervous system and no specialized organs

-They are flattened dorsoventrally and have a specialized system of tubes called protonephridia for excretion

-They are primarily hermaphroditic, meaning they have both male and female reproductive organs

-Some species of flatworms are parasitic and can cause diseases in humans and animals

Nematodes/Roundworms:

-They are thin, elongated worms that can be found in a variety of environments including soil, water, and as parasites of plants and animals

-They have a simple body structure with a tubular digestive system and a complex nervous system

-They have a complete digestive system and are heterotrophic, meaning they cannot produce their own food

-They can reproduce sexually or asexually and have a complex life cycle

-Some species of roundworms are important model organisms in scientific research

Annelids/Segmented worms:

-They are worms with segmented bodies and include species such as earthworms and leeches

-They have a well-developed circulatory and nervous system and specialized organs for respiration and digestion

-They have a hydrostatic skeleton made up of fluid-filled segments that allows them to move through muscle contractions

-They can reproduce sexually or asexually and have a complex life cycle

-Some species of annelids are important decomposers in ecosystems

Echinoderms:

-They are a group of marine animals that include sea stars, sea urchins, and sea cucumbers

-They have a unique water vascular system that helps them move and feed

-They have a tough, spiny skin and a radial symmetry

-They can regenerate lost body parts and some species can reproduce asexually through processes such as fission

-Echinoderms are important components of marine ecosystems and are ecologically and economically valuable

Mollusks:

-They are a diverse group of animals that include snails, slugs, clams, mussels, and octopuses

-They have a soft, unsegmented body and a mantle that secretes a calcium carbonate shell

-They have a well-developed nervous system and some species have highly developed senses, such as sight and touch

-They can reproduce sexually or asexually and have a complex life cycle

-Mollusks are important components of many ecosystems and are ecologically and economically valuable

Arthropods:

-They are a diverse group of animals that includes insects, arachnids, crustaceans, and millipedes

-They have a segmented body with jointed appendages and a hard exoskeleton made of chitin

-They have a well-developed nervous system and sense organs and are generally active animals

-They undergo a process of metamorphosis during their development, in which they undergo physical and behavioral changes as they grow

-Arthropods are important components of many ecosystems and play important roles as decomposers, pollinators, and as a food source for other animals
