They occur in both fresh water and salt water and occasionally in moist terrestrial habitats, especially in tropical and subtropical regions.

Where can I find Planaria?

What do Planaria eat?

Planarians swim with an undulating motion or creep like slugs. Most are carnivorous night feeders. They eat protozoans, tiny snails, and worms.

Can Planaria live without water?

If tap water is used it must be pre-treated with a Water Conditioner 21 W 2316 as recommended on the conditioner product. While planaria can survive in standing water, the water should be aerated for long- term health.

Which one of the following is found in planaria?

Planaria have three germ layers (ectoderm, mesoderm, and endoderm), and are acoelomate (they have a very solid body with no body cavity). They have a single-opening digestive tract; in Tricladida planarians this consists of one anterior branch and two posterior branches.

How do roundworms eat?
