Presentation Transcript

  1. Phylum: Cnidaria Include: Jellyfish Sea AnemonesCoral

  2. Classifications Hydrozoa; typical jellyfish Scyphozoans; colony jellyfish Anthozoans; sea anenomes, coral

  3. Typical Jellyfish Colony Jellyfish Sea Anenomes Coral

  4. Domain Kingdom Animalia Scientific Name Scyphozoa = True jellyfish

  5. Key Characteristics Hydrozoa = typical jellyfish: They have an umbrella-shaped bell and trailing tentacles. The bell is used for movement and the stinging tentacles are used for capturing prey Scyphozoans = colony jellyfish: They have no durable parts such as no head or skeleton. Consist of 98% of water.

  6. Key Characteristics Cont. Anthozoans = sea anenomes/coral Sea Anenomes Capable of catching fish Coral Capable of catching plankton

  7. Adaptations They need to be able to survive in water. They must have special body structures to do so such as their skeleton, muscles, and tentacles.

  8. Habitat Needs Aquatic animals (water). They need food such as small plankton

  9. Physiology and Reproduction Asexual reproduction involves budding, a form of natural cloning, in which a young animal forms on and then splits off of an adult. Budding can be seen in some corals and sea anemones. They also reproduce sexually, in which spawning occurs.

  10. Interesting Facts Most Cnidarians have no head, only a mouth at one end They do not have anything resembling a brain, but have nerve impulses running through them contently They have no bones, exoskeleton, or shell to protect or support them
