The Leaf-scaled Seasnake is a small, slender snake with a small head and pointed snout. The dorsal surface is dark (reddish brown or purplish) with paler cross-bands. The head scales are large and usually symmetrical. Body scales are imbricate (strongly overlapping), or leaf-like, and are in 1921 rows at the mid-body. Ventral scales are deeply notched, and number 135155. The anal scale is divided. Subcaudal scales vary between 2030. The Leaf-scaled Seasnake grows to about 60 cm in total length (Cogger 2000; Smith 1926; Storr et al. 2002) but specimens up to 90 cm have been reported (Guinea 1995). Sexual dimorphism is present in the number of subcaudal scales, with males having 2427 and females having 2029 (Greer 1997).
All seasnakes are air breathing reptiles and must come to the surface to breathe, however they can spend from 30 minutes to two hours diving between breaths. Nostril valves, which prevent water entering the lung while underwater, open inwards and are held shut from behind by erectile tissue engorged with blood (Heatwole 1999). Seasnakes have one elongated cylindrical lung that extends for almost the entire length of their body, which is very efficient for gas exchange. Seasnakes also carry out cutaneous respiration, where oxygen diffuses from sea water across the snake's skin into tiny blood vessels and carbon dioxide diffuses out (Heatwole 1999).
Seasnakes are able to avoid excess salt accumulation from sea water using a salt excreting gland that sits under the tongue. Seasnakes shed their skin every 26 weeks, which is more frequently than land snakes and more often than needed for growth alone. The process involves rubbing their lips against coral, or other hard substrate, to loosen the skin. The seasnake then catches the skin against something to anchor it and moves slowly forward, leaving the skin turned inside out behind it. Skin shedding allows seasnakes to rid themselves of fouling marine organisms such as algae, barnacles and bryozoans (Heatwole 1999).
The Leaf-scaled Seasnake is usually solitary but is sometimes found in groups at particular coral outcrops, together with other species of seasnake such as the Short-nosed Seasnake (A. apraefrontalis) and the Dusky Seasnake (A. fuscus) (McCosker 1975). These congregations contain gravid (pregnant) females (Guinea & Whiting 2005).
The Leaf-scaled Seasnake is found only on the reefs of the Sahul Shelf in Western Australia, especially on Ashmore and Hibernia Reefs (Cogger 2000; Minton & Heatwole 1975; Storr et al. 2002) in the North-west Bioregion (DEWHA 2008b).
The current extent of occurrence is estimated to be 750 km² and the area of occupancy is approximately 228 km² (Guinea 2003).
The Leaf-scaled Seasnake was the most common seasnake encountered on the reef flat at Ashmore Reef (Guinea 1995; Guinea & Whiting 2005; Minton & Heatwole 1975). However, sightings of this species have become rare on both Ashmore Reef and Hibernia Reef (Guinea 2006, 2007) and it has not been reported in surveys since 2001 (Guinea 2007; Lukoschek et al. 2013). In 2010, a dead specimen was collected from Barrow Island and deposited in the Western Australia Museum, although it is unknown whether the individual was a resident or a waif (displaced from original habitat) (Lukoschek et al. 2013).
The species features in surveys of the Sahul Shelf undertaken in 1974 (Minton & Heatwole 1975) and surveys of Ashmore Reef and Hibernia Reef between 1994 and 2007 (Guinea 1995, 2006, 2007; Guinea & Whiting 2005).
The Leaf-scaled Seasnake occurs at Ashmore Reef National Nature Reserve and Marine Park Area (Guinea & Whiting 2005).
The Leaf-scaled Seasnake occurs in shallow water (less than 10 m in depth), in the protected parts of the reef flat, adjacent to living coral and on coral substrates (Ehmann 1992b; McCosker 1975).
At Ashmore Reef, the Leaf-scaled Seasnake occurs on the reef flat during both high and low tides. It is found in exposed tidal pools during low tide, and has behavioural adaptations that enable it to tolerate the high water temperatures in pools (Guinea & Whiting 2005).
Generally, seasnakes are long-lived and slow-growing with small broods and high juvenile mortality. Little is known of the age at which seasnakes reach sexual maturity (DEWHA 2008b).
All phases of the reproductive cycle of seasnakes take place in the sea and reproductive seasonality varies among the species. All members of the Hydrophiidae family are viviparous (giving birth to live young), with a gestational period of 67 months, indicating that females are unlikely to breed every year (Cogger 1996; DEWHA 2008b).
Male seasnakes have two penises (hemipenes), each is an autonomous, independently functioning penis, but only one is used during mating. Mating takes place for long periods and seasnakes must surface for air during that time. The female controls breathing and, as she swims to the surface, the male is pulled along attached via the hemipenis. At the surface the male needs to gulp for air or he has to wait until the next time the female comes up the surface to breathe. Males are unable to disengage until mating is finished (Heatwole 1999).
Prey items recorded in the diet of the Leaf-scaled Seasnake include shallow water coral-associated Wrasse (Halichoeres sp.), gudgeons (Eleotridae), clinids (Tripterygion sp.) and eels (Anguilliformes) (McCosker 1975; Voris 1972; Voris & Voris 1983).
The Leaf-scaled Seasnake forages by searching in fish burrows on the reef flat (Guinea & Whiting 2005).
The Leaf-scaled Seasnake is similar in size and appearance to the Short-nosed Seasnake but can be distinguished by its light coloured bands (the Short-nosed Seasnake has purplish brown bands), and the 135155 deeply notched ventral scales (Short-nosed Seasnakes have 142160 broad ventral scales) (Cogger 1975, 2000).
Seasnakes that inhabit coral reefs and lagoons can be surveyed by travelling slowly along transects (for example at about 4 kn) in a small boat, and visually identifying snakes observed within 3 m of the path of the boat. Species can be distinguished by this method if the water is up to 3 m deep. A Manta board with an observer can be towed at a speed of 2 knots over transects of the reef during high and low tide. A thin tow rope 25 m in length enables surveys to be conducted on snorkel to depths in excess of 12 m when the bottom is not visible from the surface (Francis 2006; Guinea 2007). At low tide, surveys can be done on foot, for example, by searching the reef flat along transects that are 1000 m long and 20 m wide (Guinea & Whiting 2005).
Seasnakes that are swimming on the surface of the water can be captured using a dip net (Porter et al. 1997). In shallow water such as estuaries, they can also be captured in a seine net (Limpus 1975). Snakes that are underwater and either active or resting, can also be hand-netted by someone who is snorkelling or SCUBA diving, using a cylindrical net 300 mm in diameter and 1700 mm long, with 10 mm mesh. The catcher wears protective gloves and a wet suit, and gently grasps the snake through the mesh at the base of the net, drawing the snake in until the top of the net can be twisted shut (Guinea 2003; Guinea & Whiting 2005). Alternatively, snakes that are resting can be captured by grasping the snake both behind the head and by the mid-body at once. Pillstrom tongs and gloves can be used for this, although mechanical restraint may injure the snake and increase its aggressiveness (Heatwole 1975).
Threats to the Leaf-scaled Seasnake are: the direct threat from commercial fish and prawn trawling; and indirect threats from human activities and climate change.
Commercial fish and prawn trawling
While the Leaf-scaled Seasnake inhabits coral reefs, and is rare in the by-catch of trawling operations (M. Guinea 2001, pers. comm.), trawling for fish now occurs closer to reefs than it did a decade ago (Milton 2001). However, the Leaf-scaled Seasnake is seldom present in the incidental by-catch of trawl fisheries. It represented 2% of the snakes captured in trawling operations in the Arafura Sea (Shuntov 1971), and 2.9% of the by-catch during more recent fish trawling operations on the northern Australian continental shelf (Ward 1996a). Wassenberg and colleagues (2001) reported that around a quarter to three-quarters of seasnakes caught during trawling operations drowned or died from injuries, depending on the duration of trawling.
Incidental catch and death in commercial prawn trawling fisheries appears to be the biggest threat to seasnakes in the North-west Marine Bioregion (Guinea 2007). High catch rates are exacerbated by the high death rate of snakes caught in trawl nets. Even when retained aboard to recuperate, seasnakes seldom survive (Guinea 2007). Seasnakes may be more vulnerable to overfishing than other species because of their longevity and low reproductive rates. In addition, females appear to be caught more often than males (Fry et al. 2001).
The Northern Prawn Fishery (NPF) extends into the easternmost part of the North-west Marine Bioregion to Cape Londonderry and has historically had high levels of interaction with seasnakes. However, due to the small area and shorter season of the Northern Prawn Fishery in the North-west Marine Region, the number of seasnakes caught in the Region is likely to be much lower (DEWHA 2008b).
Other prawn fisheries in the North-west Bioregion, such as the Pilbara Trawl Fishery, the Exmouth Gulf Prawn Fishery and the Shark Bay Prawn Fishery, also occasionally catch small numbers of seasnakes, however, their impact on seasnake populations is considered negligible (DEWHA 2008b).
The long-term effect of climate change on seasnakes is unclear but an increase in the water temperature, frequency of bleaching events, reduced rates of calcification, increased sediment loads, higher sea levels and changes in the intensity and frequency of storm activity are also likely to have a negative effect on coral reef habitats, which are used by the Leaf-scaled Seasnake (Cogger 2000; Hobday et al. 2006).
Human activities can interact with seasnakes through the degradation of seasnake habitat. Seasnakes may be affected by oil spills and other contamination, dredging activities and increased boat traffic causing boat strikes and disruption of feeding behaviour (Cogger 2000; Hobday et al. 2006).
The decline of sea snakes at Asmore Reef are likely to be multi faceted and possibly related to overall ecosystemdecline. If habitat degradation has driven declines at the reefm than increases in live coral cover in the late 2000s may point to a potential recovery of sea snakeas (Lukoschek et al. 2013). Nevertheless, declines of this species at that reef preceeded major bleaching events in late 1990s (Lukoschek et al. 2013).
Seasnakes are becoming rare at Ashmore Reef and no Leaf-scaled Seasnakes have been recorded at Ashmore Reef for several years (DEWHA 2008b). The reason for this decline has not been identified but is likely to be environmental. A close examination of long term data sets of physical and remotely sensed data may reveal long term environmental changes that are underway on the Sahul Shelf (Francis 2006; Guinea 2007).
Turtle Excluder Devices and Bycatch Reduction Devices
Turtle Excluder Devices (TEDS) are hard grids placed in trawl nets to exclude turtles and other large animals, and Bycatch Reduction Devices (BRDs) are escape grids designed to enable smaller animals to swim out of trawl nets. The NPF has a legal obligation to avoid captures of threatened and protected species such as seasnakes, by using TEDs and BRDs. Between 2003-2006, Milton and colleagues (2008, 2009) examined the performance of different types of BRDs in the NPF and found that catches of seasnakes were reduced by 43% on those vessels where a Fisheye BRD was positioned less than 70 meshes from the codend. A separate study with a scientific observer undertook trials with a 'popeye' Fishbox BRD. This BRD reduced seasnake catch by 85%. All species had almost 100% survival in trawls of less than two hours.
Fishing vessel numbers
In 2007, there was a major reduction in the size of the NPF fleet and, by 2008, there were only 56 vessels operating, compared with 96 vessels in 2006. This change in the level of fishing effort is likely to further reduce the impact of trawling on seasnakes (Milton et al. 2008).
Marine bioregional plans have been developed for four of Australia's marine regions - South-west, North-west, North and Temperate East. Marine Bioregional Plans will help improve the way decisions are made under the EPBC Act, particularly in relation to the protection of marine biodiversity and the sustainable use of our oceans and their resources by our marine-based industries. Marine Bioregional Plans improve our understanding of Australia's oceans by presenting a consolidated picture of the biophysical characteristics and diversity of marine life. They describe the marine environment and conservation values of each marine region, set out broad biodiversity objectives, identify regional priorities and outline strategies and actions to address these priorities. Click here for more information about marine bioregional plans.
The Leaf-scaled Seasnake has been identified as a conservation value in the North-west (DSEWPaC 2012y) Marine Region. See Schedule 2 of the North-west Marine Bioregional Plan (DSEWPaC 2012y) for regional advice. The "species group report card - marine reptiles" for the North-west (DSEWPaC 2012y) Marine Region provides additional information.
