Food habits and distribution of the Lake Taal sea snake (Hydrophis semperi Garman 1881) and the sympatric little file snake (Acrochordus granulatus Schneider 1799) in Lake Taal, Philippines
Our knowledge about the food habits of sea snakes and how it is associated with their distribution has seen much development through its description across a number of species available through published literature except for the key threatened species such as Hydrophis semperi. This paper aims to describe the food habits of H. semperi through gut content and stable isotope analyses. We also compared data with the Little File Snake, Acrochordus granulatus, sympatric with H. semperi. Recorded captures of H. semperi suggest that the sea snake tends to occur in the littoral zones and the shallower portions of the limnetic zone. Gut content analysis of H. semperi have shown that gobies and eels are primary prey items. Halfbeaks (Family Hemiramphidae) were recorded as one of the Lake Taal Sea Snake's prey items which is considered as a new prey record for sea snakes. These extracted gut contents are confirmed to be the temporal food preference of H. semperi given our detected stable isotope signatures. It appears that A. granulatus and H. semperi share common prey items suggesting possible diet overlap and resource competition. This study reports the first account of the endemic Lake Taal Sea Snake's distribution and food habits which poses implications towards its conservation as it occurs in a restricted ecosystem that has undergone considerable habitat alteration.
期刊介绍:
AHR aims to provide a forum for herpetologists and related scientists interested in conducting international academic exchanges and joint studies, and a platform for introducing their newly made scientific and technological data, and publishing their research results and achievements in the world, but focusing on the Asian-Pacific Region.
The principal criteria of AHR for acceptance of articles for publication are the quality and significance of the research, breadth of interest of the work to the readership, and the clarity and effectiveness of communication. AHR welcomes submission of manuscripts from authors in all countries of the world, though with a focus on the herpetological studies in the Asian and Pacific Region, including major articles, shorter communications and review articles.
