Material
MALAYSIA: MSL BRY017b, Kuah jetty, Langkawi, fouling mussel shell attached to rope hanging from jetty. MSL BRY022, Pulau Betong, Penang, fouling a bivalve from an oyster raft. MSL BRY023, Sungai Menghulu, Langkawi, fouling a barrel.
Description
Colony encrusting, multiserial, unilamellar, except for frontal buds covering early astogenetic stages and apparent reparative growths. Autozooids subrectangular, elongate, 0.35–0.63 mm long by 0.23–0.33 mm wide; frontal shield gently convex, pustulose, porous, with large marginal areolar pores and large pseudopores, which are lacking from an apron proximal of orifice; orifice longer than wide ( Fig. 13B View Fig ), about 0.13 mm long by 0.11 mm wide, sinus broad and shallow, with medial edge almost straight, a pair of proximally directed, pointed condyles separating sinus from semicircular poster, closed by cryptocystal calcification in some zooids ( Fig. 13C View Fig ); ovicell hyperstomial, prominent, broader than long, about 0.16–0.18 mm long by 0.21–0.23 mm wide; about 10–20 rimmed pores of various shapes and sizes, becoming overgrown from the margins by a lamina of interior wall ( Fig. 13 View Fig D–E). Avicularia adventitious, small, about 0.10 mm long by 0.07 mm wide, normally located laterally to orifice and directed distolaterally towards orifice, usually single, lacking in many zooids, occasional avicularia with variable orientations present more proximally; rostrum pointed, arch-shaped; cross-bar calcified, narrow; opesia semielliptical, broader than long.
Remarks
Despite being described as late as 1978 (from Bombay Harbour), Hippoporina indica is rapidly becoming widespread as an invasive fouling species. It has been reported from the southeastern USA ( McCann et al. 2007), New Zealand ( Gordon et al. 2008) and Australia ( Tilbrook 2012), and its presence in Penang and Langkawi is therefore unsurprising.
