A Functional Biology of Scyphozoa
Embryos of Aurelia aurita develop to planulae in brood pouches formed along
the edges of the oral arms (Figures 1.6, 6.1) (Minchin, 1889; Russell, 1970).
These pouches may be tightly packed with developing embryos, making the
otherwise ...

Coral Reef Restoration Handbook
Two approaches to reef restoration exist: transplanting all or portions of adult
corals and releasing planulae raised in the laboratory on damaged reefs. It has
long been known that colonial corals have the capacity to survive and grow after

Further possibilities are presented by the fusion of recently settled planulae
which then give rise to colonies having the same form as those which arise from
a single planula. Fusion of planulae has been observed in species of Sidemstrea
, ...

It is likely that most rhizostomids and some semaeostomes (e.g. Aurelia aurita,
Hamner & Jenssen 1974; Cyanea, Brewer 1989), brood the developing planulae
before they are released. Planulae were found on adult Cotylorhiza tuberculata ...

Marine Chemical Ecology
The scyphozoans Cassiopea andromeda and C. xamachana produce both
sexual planulae, which develop from fertilized eggs, and asexual buds, liberated
from the polyp-stage scyphistomae, which swim, behave, and settle in much the ...

The settlement of planulae on artificial substrata in chronic exposures to
pollutants in the laboratory would appear to be an attractive bioassay, but care
must be taken in selection of planulae for use in such experiments. Rinkevich
