You have described body plan of a medusa...... and a jellyfish is a good example of a medusa.
A medusa looks like an umbrella and a polyp any idea!
Yes. One body type is called the polyp. It is cylindrical in shape, having a mouth at the top surrounded by tentacles with stinging cells. Polyps attach to substrates. Coral polyps and sea anemones are examples of the polyp body type. The other body type is called the medusa, which has a bell or umbrella shape with the mouth facing down and surrounded by tentacles with stinging cells. Jellyfish are the best known examples of the medusa body type.
The first body plan is a Medusa bosy plan which is like a jellyfish the one above is a medusa. the mouth it located at the bottom of the body. The appendeges are also located at the bottom. A polyp (on the right) ,like a sea anemone, has the appendeges at the top along with the mouth. They are also attached to solid ground unlike Medusas.
