“…However, uncertainties remain in coral reef and rocky fish assemblages when compared to other coastal habitats, mainly due to the difficulty in capturing specimens. In addition to U. xenodontus reported here, other poorly known fish species have been found in recent investigations of sea krait stomach contents (Tabata et al 2017). As evident here and also suggested by Ineich et al (2007) and Séret et al (2008), examination of the stomach contents of sea kraits provides an additional useful tool for investigating the diversity of tropical and subtropical fishes.…”

“…at Iriomote and Ishigaki islands in Japan, 2 moray eel specimens of the genus Uropterygius Rüppell, 1838 (Muraenidae, Uropterygiinae) were recovered from Laticauda colubrina (Schneider, 1799). One was identified as Uropterygius nagoensis Hatooka, 1984, while the other remained unidentified (Tabata et al 2017). We provisionally identify this specimen as Uropterygius xenodontus McCosker & Smith, 1997-a species known only from the type series collected from central and western South Pacific.…”

“…Details of specimen collection were given by Tabata et al (2017). Counts and measurements generally follow McCosker and Smith (1997), measurements being made to the nearest 1 mm with a metal ruler for the total, trunk, preanal and tail lengths; and to 0.1 mm with digital calipers for other measurements.…”

“…have a key role as predators of coastal fishes in tropical and subtropical regions. Some species specialize on feeding of anguilliform fishes, despite a large variety of co-existing fishes (McCosker 1975, Ineich et al 2007, Tabata et al 2017. When studying the stomach contents of Laticauda spp.…”

“…Currently, we have a good understanding of the diet of many species of marine snakes based on analyses of stomach contents of true sea snakes (Glodek and Voris, 1982;Voris and Voris, 1983), sea kraits (Brischoux et al, 2009c;Tabata et al, 2017), acrochordid (Voris and Glodek, 1980), and homalopsid snakes (Voris and Murphy, 2002). Some species are known to have extremely specialized diets (e.g., Fish egg specialists; Voris, 1966;Sanders et al, 2012).…”

Marine snakes represent the most speciose group of marine reptiles and are a significant component of reef and coastal ecosystems in tropical oceans. Research on this group has historically been challenging due to the difficulty in capturing, handling, and keeping these animals for field-and lab-based research. Inexplicable declines in marine snake populations across global hotspots have highlighted the lack of basic information on this group and elevated multiple species as conservation priorities. With the increased interest in research on marine snakes, we conducted a systematic survey of experts to identify twenty key questions that can direct future research. These questions are framed across a wide array of scientific fields to produce much-needed information relevant to the conservation and management of marine snakes.

Challenges of regulating commercial use of marine elapid snakes in the Indo‐Pacific

Marine elapid snakes are a diverse, predominantly Indo‐West Pacific species group. The persistent removal of some species has an unquantified but potentially dire impact on populations. We conducted the first comprehensive review of the trade in marine elapid snakes based on published literature (1974–2022) and trade data from the only species (i.e., Hydrophis [Lapemis] curtus) whose trade is monitored internationally. Some species and populations were subjected to targeted harvest for their meat and skins for at least the last century; fisheries are possibly the most significant threat to populations of marine elapids, with the highest numbers being exploited either accidentally, incidentally, or opportunistically in Southeast Asian fisheries targeting other seafood, including demersal trawl and squid fisheries. Southeast Asia is the core region for exploitation of marine elapids. Annual offtake is >225,000 individuals of at least 8 species in the Gulf of Thailand. Of 72 recognized marine elapids (all non‐CITES [Convention on International Trade in Endangered Species of Wild Fauna and Flora] species), Hydrophis curtus and Hydrophis cyanocinctus dominate the skin trade. Skins of H. curtus are traded mainly in East and Southeast Asia and, to some extent, Europe. Despite some baseline information on the trade of these species, the sustainability of their harvests, particularly in the context of the burgeoning and unmanaged nature of fisheries in the region, remains the major challenge. In an era of declining fish stocks, there has been an increasing trend to commercialize the harvest and use marine elapids that were once considered accidental bycatch and discarded. This trend will continue to pose a significant risk to these snakes unless appropriate fisheries and trade regulations are enforced. Applying the precautionary principle to prevent the overexploitation of sea snakes is an indispensable measure in which trade in regional populations should be regulated through CITES. Accordingly, management plans to identify core distribution regions of exploited species would be crucial for assigning national responsibilities to sustain species and populations in the long term.
