Planarians are carnivorous creatures that feed on small invertebrates like worms, snails, and insect larvae. They use their muscular pharynx to suck in their prey and digest it externally. Planarians are opportunistic feeders and will also scavenge on decaying organic matter.

Are planarians herbivores?
Yes
Why do planarians regenerate?
Planarians are able to regenerate because they have a population of adult stem cells called neoblasts that can differentiate into any type of cell needed. These neoblasts are responsible for the continuous growth and renewal of tissues in planarians, allowing them to regenerate lost body parts.
Is it true that adult planarians can focus well enough with their eyespots to form images of objects in their environment?
No, adult planarians are not able to form detailed images of objects in their environment with their eyespots. Eyespots are light-sensitive organs that can detect light and shadows, but they do not have the ability to create detailed images like a true visual system. Planarians rely more on their chemosensory capabilities for navigating their environment.
Do planarian have tissue?
Yes, planarians have well-defined tissues that make up different parts of their body, including muscle, nerve, reproductive, and digestive tissues. These tissues enable planarians to perform various physiological functions such as movement, digestion, and response to stimuli.
Explain how feeding and digestion occur in planarians?
Planarians eat by extending their pharynx to ingest food, which then moves to the gastrovascular cavity for digestion. Once in the stomach, food particles are broken down by enzymes before nutrients are absorbed into the cells lining the cavity. Waste is then excreted through the pharynx.
Are planarians symetrical?
Planarians have bilateral symmetry.
Are planarians non parasitic flatworms?
Yes, planarians are non-parasitic flatworms
Planarians are parasitic segmented worms?
Planarians are neither parasitic or segmented. They are flatworms.
What are structures that enable planarians to expel liquid waste?
The structures that enable planarians to expel liquid waste are normally pores. The pores are found on the dorsal surface of the planarians.
How do planarians move?
Planarians move by expanding and contracting their bodies as they grip a surface.
What phylum contains planarians?
Planarians belong to the phylum Platyhelminthes.
Are planarians herbivores?
Yes
Do Planarians have a scientific name?
Yes, all organisms have scientific names. Thus planarians have scientific names too.
What phylum does the planarians belong to?
Platyhelminthes.
Do planarians lay eggs?
yes they do
Are planarians predators?
other worms
What type of food can you find planaria?
Well Planarians like to eat Chicken and Hotdogs! I am having to find some for extra credit for my biology class.Good luck
