Types of Organisms:
The Cnidaria phylum is extremely complex, and has four groups of organisms. Thankfully, http://www.mesa.edu.au/Cnidaria/default.asp provides us with pictures of almost all of them.

Type of Symmetry:
According to http://www.encyclopedia.com/plants-and-animals/animals/zoology-invertebrates/cnidaria, ALL Cnidaria (Jellies and Coral animals alike) are radial in symmetry, meaning there's always a central axis that they can be divided evenly from.

Reproduction Method:
https://www.reference.com/pets-animals/cnidaria-reproduce-1ba5faf6cc2a6340 informs us that, much like their Porifera pals, most jellyfish and coral animals can reproduce either sexually or asexually. A lot of them are also dioecious and can be either gender! Amazing!

What’s the difference between a Medusa and a Polyp?:
To put it simply, the major difference is that Polyps are fixed, cylindrical, and reproduce by budding, whereas Medusae can move around freely, are umbrella shaped, and reproduce sexually. Medusae also have Gonads and sensory organs that Polyps lack.

What is the purpose of a Cnidarian’s tentacles?:
http://www.oceanicresearch.org/education/wonders/cnidarian.html enlightens us by explaining how Cnidarians have little stingers hidden in their tentacles called nematocysts, and how these nematocysts are used to disable prey by injecting toxins, MOST of which are not harmful to humans. As a bonus, did you know that Cnidaria literally translates to “Stinging creature”?

Lastly, what do YOU find interesting about these animals?:
The amount of variety they have, mainly! Jellyfish, Coral, Man-o-wars, all fit snugly into a single phylum! The amount of similarities they have is quite astonishing, if I do say so myself! It's also quite a shock to see how much different the main groups can be, while still sharing common characteristics!
