Abstract/Summary

Sponges in nine sampling sites (Clubhouse 2A, Galvez 5A, Inner Talim 6A, Middle Duenas Reef, Layag-layag 3A, Outer Talim 7A, Torso 4A, Roces Mangrove waterway and Roces) in Talim Bay, Lian, Batangas were collected from May 2-8, 2009. Twentyfour different sponges collected belong to Class Demospongia. Only 21 were identified and classified into 10 families: Halichondriidae, Clionaidae, Axinellidae, Chondropsidae, Ircinidae, Petrosiidae, Microcionidae, Chalinidae, Niphatiidae, Callyspongiidae; and 14 genera: Ciocalypta, Spheciospongia, Axinella, Phoriospongia, Sarcotragus, Petrosia (Strongylophora), Xestospongia, Clathria, Haliclona, Haliclona (Gellius), Chalinula, Niphates, Callyspongia and Callyspongia (Cladochalina). The sponge collection was dominated by genus Haliclona obtained from Clubhouse 2A, Outer Talim 7A, Torso 4A, Roces mangrove waterway and Roces. At the species level, only Callyspongia (Cladochalina) samarensis, Haliclona (Gellius) sigmadocia, Xestospongia testudinaria and Chalinula nematifera were identified and verified. Comparison of the current survey with Elmido et al. (1995) revealed more diverse in terms of genera species identified. Seven (29%) of the 24 sponges collected in the present survey were of genus Haliclona, of which Haliclona (Gellius) sigmadocia was identified and verified. None of the 41 sponge species in the collection of Elmido et al. (1995) were of genus Haliclona. Genus Petrosia and Xestospongia represented the more dominant genera in the sponge collection of Elmido et al. (1995), and both genera were also identified in the current study. Other less represented genera in 1995 that have been likewise identified in the current survey are Xestospongia, Clathria, Petrosia, Petrosia (Strongylophora), Ciocalypta, Callyspongia, Callyspongia (Cladochalina) and Niphates.
