Snowdrop hydroid : ウィキペディア英語版 | Snowdrop hydroid
The snowdrop hydroid, ''Gattya humilis'', is a delicate colonial hydroid in the family Halopterididae.〔http://marinespecies.org/aphia.php?p=taxdetails&id=289983 accessed 19 August 2013〕 ==Description== Snowdrop hydroids are usually white and have small branches extending from a central stem. They may grow up to 3cm in total height. The male gonophores (reproductive bodies) are smaller and more rounded than the female ones, which are goblet-shaped and contain only one egg each. Both sexes occur on the same stem.〔Millard, N.A.H. 1975. Monograph on the Hydroida of Southern Africa. ''Ann. S. Afr. Mus.'' 68:1-513〕
