Like other advanced multicellular animals, they possess three embryonic layers—endoderm, mesoderm, and ectoderm—and have a head region that contains concentrated sense organs and nervous tissue (brain).
What is unique about flatworms?
Features of Flatworms Flatworms have no true body cavity, but they do have bilateral symmetry. Due to the lack of a body cavity, flatworms are known as acoelomates. Flatworms have an incomplete digestive system. Most flatworms have a distinct head region that includes nerve cells and sensory organs, such as eyespots.
How are flatworms and roundworms similar to segmented worms How are they DIfferent?
Flatworms (phylum Platyhelminthes) are simple animals that are slightly more complex than a cnidarian. Roundworms (phylum Nematoda) have a slightly more complex body plan. Segmented worms (phylum Annelida) are the most complex animals with worm-like body plans. Worms are invertebrate animals with bilateral symmetry.
How do you identify a jumping worm?
Asian jumping worms are smooth, glossy gray or brown and 1.5 to 8 inches long. They are relatively easy to identify if you take a look at their clitellum (the band around the body of a worm).

Are Jumping Worms good fish bait?
The worm, Amynthas spp, is native to East Asia but is believed to have been brought into the U.S. as fishing bait. Scientists warn they feed on organic matter in soil, eating many of the crucial nutrients that plants, fungi and animals require to thrive.
