| Question | Answer |
|---|---|
| What are tiny, stinging structures that are triggered by mechanical stimulation. They are coiled and ready to be released when stimulated | Nemoatocysts |
| What are found within Cnidocytes (Specialized cells in the tentacles). | Nemoatocysts |
| What are used to capture prey and for defense against predators | Nemoatocysts |
| are part of the class Hydrozoa | Hydrozoans |
| Polyp dominant. | Hydrozoans/Anthozoans |
| Larval Stage = Medusa. Adult State = Polyp | Hydrozoans |
| Have Zooids - Polyps with different morphological forms that make up colonial cnidaria. They perform different functions for feeding, reproduction, and defense. | Hydrozoans |
| Produce Planular Larvae through sexual reproduction - Larvae that swim. | Hydrozoans |
| Some species are solitary, while others are colonial. | Hydrozoans |
| are part of the class Schyphozoa. They consist of larger ¨true¨ jellyfish. | Scyphozoans |
| Medusa dominant with a rounded bell shape. | Scyphozoans |
| The medusa is the dominant stage of their life cycle. | Scyphozoans |
| Species that live in the deep ocean can grow up to 3 meters wide. | Scyphozoans |
| Swim with rhythmic contractions of the bell, but this can be greatly impacted by the strength of currents. | Scyphozoans |
| are part of the class Cubozoa | Cubozoans |
| Consists of box jellyfish and sea wasps. | Cubozoans |
| They are mostly transparent, shaped like a cube and they have a minimum of 4 tentacles. | Cubozoans |
| They are known to be the most dangerous marine organisms with powerful stings that can be lethal. | Cubozoans |
| Mostly found in Australia. | Cubozoans |
| are part of the class Anthozoa | Anthozoans |
| Species include corals, anemones, and sea fans. | Anthozoans |
| Coral exoskeletons are made up of Calcium Carbonate (CaCO3). | Anthozoans |
| Found in intertidal zones, | Anthozoans |
| Sea anemones usually have large, colorful polyps. | Anthozoans |
| Octocorals (Soft Corals) do not build calcium carbonate skeleton but rather have internal structural support so they can sway with the currents. | Anthozoans |
| Octocorals have 8-fold symmetry, meaning their tentacles come in groups of 8. | Anthozoans |
| are of the phylum Ctenophora and consist of comb jellies. | Ctenophores |
| They swim by using 8 Ciliary Combs that are fused at the base. | Ctenophores |
| They are mostly planktonic and exclusively marine. | Ctenophores |
| are characterized by eight rows of cilia, which are used for locomotion. | Ctenophores |
| They lack stinging cells. To capture prey, they use colloblasts, which are sticky cells. | Ctenophores |
