title: Population ecology of a colonizing species: The pelagic tunicate Thalia democratica : I. Individual growth rate and generation time.
abstract: The marine pelagic tunicate Thalia democratica has one of the fastest individual growth rates and shortest generation times of any multicellular animal. Measurements of growth in the laboratory and at sea show that this salp maintains a growth rate of over ten percent in length per hour for much of its life cycle. This salp develops through bot generations in a minimum of two days. This generation time increases to over two weeks under conditions of poorer food or lower temperature. Maternal nutrition and viviparity are among the many specialized adaptations which allow this animal to achieve such rapid growth.
