Seven coral reef-associated and deep-water fish species were found in a local fish market on 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. We also measured the largest specimen ever for B. 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. Seas surrounding the more than islands of the Philippine archipelago host the highest biodiversity of marine fauna in the world, including the teleost fish Tittensor et al.
For decades, the Philippine marine fish have been intensively studied covering topics such as taxonomy and distribution e. However, the vast majority of ichthyological studies were conducted in the northern Luzon and central seas Visayas of the country, which form the epicentre of marine species diversity within the Coral Triangle Hoeksema, ; Sanciangco et al.
A much lower number of studies has been carried out in the southern Island of Mindanao especially along the western and southern shores , as this region has suffered under scenes of political unrest. For that reason, the development of a research infrastructure has been hampered and knowledge about Mindanao's natural resources is limited.
The Davao Gulf, a large bay located in south-eastern Mindanao bordering the Celebes Sea, is one area of which little biological information is known. Therefore, it may not be surprising that recent studies have revealed unique ecological phenomena Bos et al. Networks of MPAs have been created to conserve species diversity, but knowledge of spatial distributions of many species remains incomplete Dalleau et al. Furthermore, climate change impacts marine biodiversity through changes in species distributions e. For these reasons, it is of utmost importance that new records of fish species, contributing to expanding geographical distributions, are reported.
The present study describes new records of fish found in a local market on Samal Island and discusses their specific range extensions. It further provides morphometric data and describes, when appropriate, length—weight relationships and the seasonality of occurrence. Species identification was usually done on the spot, but representatives of unidentified species were photographed to support later identification.
Additional photographs were made of fins and other conspicuous characteristics. High-resolution photographs were used to count spines, rays, scales, etc. Measurements were conducted during 7. Specimens 37 in total were measured on 2 July 3 specimens , 5 October 1 , 10 February 11 , 19 February 2 , 26 February 5 , 5 March 2 , 16 April 4 , 3 September 3 , 1 December 2 , 14 December 3 and 18 May 1. The anterior dorsal fin had 11—12 slender spines; the first 3—5 spines were black, whereas the remaining fin had a grey colour. The posterior dorsal fin had 15 soft rays and a grey colour.
The caudal fin was generally grey, had a dark edge and the tips of both lobes were black. The dorsal and caudal fins had a light yellow shine in some specimens. The anal fin had two spines, 14—15 rays and was white in colour. The pectoral fins had 23 rays, were black, but became gradually white toward their ventral sites. The pelvic fins had one spine, five rays and were white.

The body was elongated and rounded with a general silver appearance. The nape and the dorsal areas were darkened. Most specimens had a black marking at the posterior, dorsal edge of the eye. In January , this species was observed in Hurghada, Egypt, which also constituted a new national record A.

Colour of the body dark blue with a bright yellow band from snout, through the eye, along the back to the caudal fin. Proximal end of dorsal fins bright yellow being part of the band.
Caudal fin base bright yellow. Proximal end of first rays of pelvic fin yellow. Thin yellow line along the margin of the maxilla. Fin rays except in pectoral fins dark blue and tissue translucent to grey. Body brightly orange with a red stripe and white margins from the opercular flap to the caudal fin base.
