Popis: | Galathea amboinensis De Man, 1888 and G. inflata Potts, 1915, both known as associates of shallow water co- matulid crinoids, are reported for the first time from Japan. In the Ryukyu Is lands, Galathea inflata was found on 13 species of crinoids but most commonly on Comanthus parvicirrus (Miiller) and Comaster schlegelii (Carpenter). Gala thea amboinensis was recorded from 10 crinoid species but more often on Capil- laster multiradiatus (Linnaeus) than on other crinoids. Heterosexual pairs of G. inflata were found on 26.3 % of host crinoids (n=57), and all females were ovigerous. Megalopae of both galatheids were found on hosts, indicating that the larvae settled on crinoids at the megalopa stage. |
