|
| 42. | Individuals in bryozoan ( ectoproct ) colonies are called zooids, since they are not fully independent animals.
|
| 43. | The atrial siphon of the oozoid becomes the exhalent siphon for the new, four-zooid colony.
|
| 44. | When the telotroch finds suitable environs it reattaches to the substrate and transforms back into a stalked zooid.
|
| 45. | The early developmental stages take place inside the zooid and the larvae are later liberated into the sea.
|
| 46. | The lophophore is controlled by the zooids nervous system, which consists of a ganglion at the lophophore base.
|
| 47. | The convergently evolved an opercular structure during the Early Cretaceous to Paleocene, also possess avicularia-like zooids.
|
| 48. | The colony can grow by budding, a form of asexual reproduction, new zooids growing from the stolon.
|
| 49. | Some freshwater species secrete a mass of gelatinous material, up to in diameter, to which the zooids stick.
|
| 50. | Even though colonies of zooids grow through asexual reproduction, Bryozoans are hermaphrodites and colonies are started through sexual reproduction.
