The spermatagonia develop more quickly than oogonia, resulting in a protandrous
oyster (Coe 1931b).
We sampled channeled whelk in Buzzards Bay, Massachusetts, and expected that they would be protandrous
hermaphrodites as reported for laboratory-reared knobbed whelk by Castagna and Kraeuter (1994).
arrival timing to breeding areas: a review.
The gonadal anatomy and sexual pattern of the protandrous
sex-reversing fish, Rhabdosargus sarba (Teleostei: Sparidae).
Alstroemeria, Bomarea, and Pentagonia are protandrous
The morphology of gonadal tissue and male germ cells in the protandrous
black porgy, Acanthopagrus schlegeli.
They are strongly protandrous
, with pollen already mature and sometimes shed within the bud.
calcarifer is a protandrous
fish found in estuaries and other coastal areas of the Indo-West Pacific (Griffin, 1987).
margaritifera is a protandrous
hermaphrodite (Tranter 1958a).
The combination of our direct observations and Skottsberg's observations (1928), together with generalizations from published data for some continental genera or families, indicate that around 30% of the species are or should be protandrous
and 7% protogynous.
Our study examined age, growth, maturation, and sex reversal of common snook which previously had not been diagnosed as being protandrous
maxima is a protandrous
hermaphrodite, with a 50:50 male-to-female ratio at a size of 170 mm in Western Australia (Hart & Joll 2006), but more females than males can be expected to occur at sizes larger than 170 mm.
