ABSTRACT A large solitary polyp of the genus Pseudocorynactis (Corallimorpharia) was observed to prey on the crown-of-thorns starfish (Acanthaster planci), which itself has destroyed large areas of coral reefs by solely feeding on the polyps of reef-building corals. We observed Pseudocorynactis sp. to prey on echinoderms and to completely ingest starfishes, including the crown-of-thorns starfish, up to 25 cm in diameter. This newly discovered predator may play a key role in the ecology of crown-of-thorns outbreaks by controlling the juvenile and sub-adult populations of this starfish.

    ABSTRACT: The free-living solitary mushroom coral Heliofungia actiniformis resembles sea anemones by having large, fleshy polyps with long tentacles, which provide shelter to symbiotic organisms. Commensal shrimps are well studied, but little is known about associated fish fauna. Therefore, the associated fauna of 118 coral polyps of H. actiniformis was examined at a depth range of 4–28 m in the Davao Gulf, Philippines. The distribution of associated fishes and symbiotic invertebrates highly depended on the size of the coral host: Large corals polyps (>18 cm) supported co-inhabiting fishes and commensal shrimps, medium-sized polyps (diameter 5–18 cm) hosted either fishes or shrimps, and small coral polyps (Eviota lachdeberei and E. rubriceps, and the labrid Oxycheilius celebicus were most common, making up for 77 % of all fishes encountered. Total length of the fish ranged from 1 to 6 cm covering adult gobies and juveniles of the other families. Four species of commensal shrimps were hosted by the coral polyps. This study further constitutes the first record of brittle stars of the genus Ophiothrix (Echinodermata: Ophiuroidea) living among tentacles of H. actiniformis.

    ABSTRACT: The goatfish, Upeneus nigromarginatus new species, is described based on 5 specimens (151–196 mm) purchased at a fish market in Panabo City, Mindanao, Philippines. This species is diagnosed by the following counts and external morphology: dorsal fin rays (VIII, 9–10), pectoral fin rays (16), lateral line scales (36–37), total number of gill rakers (25–26), and anal fin rays (I–II, 6). When compared to congeners, U. nigromarginatus new species has a relatively deeper body (31.1–34.8% in SL vs. <30% in SL), shorter snout (7.1–9.0% in SL vs. >9.6 % in SL), and longer pectoral fin (27.7–29.1% in SL vs. <25 % in SL). Upeneus. nigromarginatus new species, has neither stripes on the body, nor bands on the caudal fin. However, a black band borders the distal edges of both the first and second dorsal fins, and at the posterior edge of the upper lobe of the caudal fin; hence the proposed common name ‘black-margined goatfish’. The posterior edge of the ventral caudal lobe has a white margin. The comparisons of a fragment of the Cytochrome C Oxidase Subunit I (COI; 28 specimens representing 10 Upeneus species) and 34 morphometric parameters (Principle Component Analysis; 56 specimens representing 5 genera and 12 mullid species) supported the description of U. nigromarginatus new species.

    ABSTRACT: Seven coral reef-associated and deep-water fish species were found on a local fish market in Samal Island in the Davao Gulf, constituting the first records for the Philippine archipelago. The specific geographical distributions of Eumegistus illustris (Bramidae), Paracaesio kusakarii (Lutjanidae), and Saloptia powelli (Serranidae) are greatly enlarged by these observations. The first records of Ariomma brevimanum (Ariommatidae), Brama orcini (Bramidae), Aulacocephalus temminckii (Serranidae), and Pseudanthias fasciatus (Serranidae) confirm the Indo-Pacific-wide distributions of these species. In contrast to the other records, A. brevimanum and B. orcini were encountered regularly and length weight relationships, not earlier provided in the scientific literature, were calculated. We also measured the largest specimen ever for B. orcini (Total Length of 420 mm). These observations substantiate the uniqueness of the poorly-studied fauna of the southern Philippines and underline the importance of marine Philippine fauna within the Coral Triangle.
