“…Both conger (Congridae) and moray (Muraenidae) eels were reported in the stomach contents of H. cyanocinctus from the Gulf of Mannar off Tamil Nadu in India [18]. Mudskippers (Periophthalmus waltoni, Boleophthalmus dussumieri and Scartelaos tenuis), and Parachaeturichthys polynema comprising the vast majority of the diet of this species in the Hara Protected Area on the North Coast of the Persian Gulf, Iran [19].…”

“…Intertwining of two Hydrophis cyanocinctus is sometimes observed in the mangrove channels of the same ecosystem and other mangrove stands in the area (Figure 20; for more details see Rezaie-Atagholipour et al 2012). Rezaie-Atagholipour et al (2013) studied feeding habits of the same population in the biosphere reserve and found that main prey items for Hydrophis cyanocinctus in this protected area are the mudskippers (Gobiidae, Oxudercinae). The venom proteomes were also investigated for the same population of Hydrophis cyanocinctus in the Hara Biosphere Reserve of the Persian Gulf (Calvete et al 2012; Khorjestan et al 2016).…”

The Persian Gulf is known as the westernmost distribution limit for sea snakes, except for Hydrophis platurus (Linnaeus, 1766) that reaches southeastern Africa. Previous identification guides for sea snakes of the Persian Gulf and its adjacent waters in the Gulf of Oman were based on old data and confined mostly to written descriptions. Therefore, a series of field surveys were carried out in 2013 and 2014 through Iranian coastal waters of both gulfs to provide a comprehensive sampling of sea snakes in the area. This paper presents an illustrated and updated checklist and identification tool for sea snakes in the Persian Gulf and Gulf of Oman, which are based on new material and a review of the literature. This checklist includes ten species of marine hydrophiines, of which one, Microcephalophis cantoris (Günther, 1864), is a new record for the area. All specimens examined herein are deposited and available at the Zoological Museum of Shahid Bahonar University of Kerman, Kerman province, Iran.

“…For such a species, foraging may be substantially affected by the tide. This is the case for Hydrophis cyanocinctus, which forage at low tide for mudskippers trapped within their burrows by the falling water levels 27 . A trend for Hydrophis curtus to move into areas where and when tidal fluctuations in water levels are maximal 16,17 might well reflect availability of otherwise-shallow inshore areas that provide feeding opportunities.…”

The behaviour of sea snakes (Emydocephalus annulatus) shifts with the tides

Tidal cycles are known to affect the ecology of many marine animals, but logistical obstacles have discouraged behavioural studies on sea snakes in the wild. Here, we analyse a large dataset (1,445 observations of 126 individuals) to explore tidally-driven shifts in the behaviour of free-ranging turtleheaded sea snakes (Emydocephalus annulatus, Hydrophiinae) in the Baie des Citrons, New Caledonia. Snakes tended to move into newly-inundated areas with the rising tide, and became more active (e.g. switched from inactivity to mate-searching and courting) as water levels rose. However, the relative use of alternative habitat types was largely unaffected by tidal phase. Results We obtained data on 1,445 sightings of 126 individuals (1-39 sightings per snake). The sample size of sightings was slightly male-biased (57% vs. 43%) as was the overall sex ratio (68 males, 57 females). Reflecting ease of sampling, we gathered more data at high tide (50% of sightings) than at medium (28%) or low (22%) tides. Snakes were sighted most often while they were foraging (54% of observations) or inactive (34%), and less often while they were mate-searching and courting (10%) or being courted (2%).
