Platyhelminthes, commonly known as flatworms, typically have a flattened, elongated body shape that is bilaterally symmetrical. This flat morphology allows for a high surface area-to-volume ratio, which facilitates gas exchange and nutrient absorption. Their bodies are soft and unsegmented, often exhibiting a tapered or rounded end. Some species may also display distinct regions, such as a head or anterior end, with specialized structures.

Phylum name for planarian?
The phylum name for planarians is Platyhelminthes, which includes flatworms like the planarian. They are characterized by their flattened body shape and bilateral symmetry.
Why animals of platyhelmenthis are known as flatworms?
Animals of the phylum Platyhelminthes are known as flatworms because their bodies are dorsoventrally flattened, giving them a thin and flat appearance. This flat body shape allows for efficient gas exchange and nutrient absorption through their body surface.
What is a common feature of phylum platyhelminthes?
A common feature of phylum Platyhelminthes is their flattened, ribbon-like body shape, which gives them their name (platy meaning flat). They also lack a body cavity (coelom) and have a simple nervous system with nerve cords and ganglia.
What are the characteristics of PLATYHELM?
Platyhelminthes, commonly known as flatworms, are soft-bodied invertebrates with a flattened body shape. They exhibit bilateral symmetry and lack a coelom (body cavity). They are hermaphroditic, meaning they have both male and female reproductive organs.
What are the types of coelom of platyhelminthes?
Platyhelminthes have an acoelomate body plan, which means they lack a true coelom. Instead, they have a solid body with a more primitive digestive cavity and lack a fluid-filled body cavity like true coelomates.
How do Platyhelminthes breathe?
Platyhelminthes breathe using their entire body. Being flat, oxygen diffuses quickly across the skin and to all parts of the body, so they don't need a blood circulatory or respiratory system.
What is a plathyhelminthes?

Scientific name for flatworms?
The scientific name for flatworm is Platyhelminthes.
What phylum do flatworms belong to?
Flatworms are in the Platyhelminthes Phylum
Do Platyhelminthes have warm or cold blooded?
Platyhelminthes, or flatworms, are ectothermic organisms, meaning they do not regulate their body temperature internally and are typically considered cold-blooded. Their body temperature is influenced by the surrounding environment. As a result, their metabolic processes and activity levels can vary with temperature changes in their habitat.
