There are tens of thousands of types of worms on our planet, and these wiggly wonders are oh-so fascinating that we had to put together different stories about them to reveal just how 'wormdeful' they are.

With Annelida covered, it's time to start looking at some of the smaller phyla that are closely related. First up is Nemertea, the ribbon worms. These are very thin and live in the sea, and they have some very interesting features. Take...

In this video students will learn that evolutionists always had a difficult time explaining how the eye evolved because of its complexity. Using real world examples and diagrams, viewers will learn the various stages of the eye’s...

Scientists have discovered that an invasive species of flatworms have been quietly occupying French soil for the past two decades.

Upon viewing the Simple Animals video series, students will be able to do the following: Differentiate between and provide examples of vertebrate and invertebrate animals. Describe the basic body parts of a sponge (porifera). Explain...

The first phylum within Spiralia that we will investigate is Platyhelminthes. These are the so-called flatworms. What are their characteristics? What are the clades within this phylum? Let's set ourselves up for a thorough...

With the basics regarding phylum Platyhelminthes covered, it's time to start digging into the clades within. Free-living flatworms were originally classified within the class Turbellaria. But more recently the clades needed to be...

The phylum gastrotricha (also known as hairybellies) is a group of very small marine creatures that resembles a cross between a flatworm and a rotifer. Let's learn about the anatomy and reproduction of gastrotrichs.



Spiralia...

It explains the key characteristic features and common examples of animals belonging to Phylum Platyhelminthes.

It's time to start digging into Nephrozoa, which is going to take a really, really, really long time to cover. The first major clade within that we will tackle is Spiralia. This includes well-known phyla like Mollusca and Annelida, but...

Flatworms Simple Wiggly Tubes

Biological Classification Set: This clip looks at the three major phyla of worms: the Platyhelminthes, Nematoda and Annelida. As well as examining the phylum Mollusca.
