Study Notes
Ctenophores
- The main method of movement for ctenophores is through the use of cilia, which are hair-like structures that propel them through the water.
- Adult ctenophores can grow up to 15 centimeters in length, although some species can reach sizes of up to 1 meter.
Body Form of Cydippids
- The body form of cydippids, a type of ctenophore, is distinguished by their oval-shaped bodies and pair of retractable tentacles.
Beroids
- Beroids, a type of ctenophore, primarily prey on small invertebrates, such as bristle worms and crustaceans.
Ctenophore Fossils
- The fossils thought to represent ctenophores are notable for their lack of hard body parts, making it difficult to identify them as ctenophores.
