'''Belchers havslange''' ([[latin]]: ''(Hydrophis belcheri)'') er verdens giftigste [[slange]]. Blot et enkelt gram gift er rigeligt til at slå 12.900 mennesker ihjel.{{kilde mangler|dato=Uge 32, 2009}}. Den har et venligt temperament og skal normalt udsættes for hårdhændet behandling før den bider. De fleste som bides er fiskere som røgter garn, men heraf er det kun en fjerdedel som forgiftes, eftersom slangen sjældent injicerer særligt megen af sin gift. Af denne grund og på grund af sit rolige væsen, betragtes den ikke generelt som særlig farlig. Giftigheden af denne slanges gift er flere gange blevet draget i tvivl, og flere herpatologer og slange-entusiater udnævner ''[[Enhydrina schistosa]]'' og ''[[Oxyuranus microlepidotus]]'' til at have den farligste gift. <ref>http://www.jcu.edu.au/school/tbiol/zoology/herp/Enhydrinaschistosa.PDF</ref><ref>[http://www.4to40.com/QA/index.asp?id=631&category=animal Question:What is the most venomous snake on the planet?,Children's find simple answers for What is the most venomous snake on the planet?,animal FAQ's,School Notes for What is the most venomous snake on the planet?,Kids question:What is the most venomous snake on the planet?<!-- Bot generated title -->]</ref><ref>http://www.phcog.net/phcogmag/issue9/11.pdf</ref><ref>[http://web.archive.org/web/20070928121748/http://www.cfrar.com/venomoussnakes.htm The Center for Reptile and Amphibian Research: The Most Venomous Snakes<!-- Bot generated title -->]</ref><ref>[http://animal.discovery.com/fansites/crochunter/australiazoo/10mostvenomous.html Animal Planet :: Australia Zoo – Venomous Snakes<!-- Bot generated title -->]</ref><ref>[http://web.archive.org/web/20080118012414/http://www.barefootbushman.com/venoms.htm Relative Toxicity of Australian Snakes<!-- Bot genereret titel -->]</ref><ref>[http://www.seanthomas.net/oldsite/ld50tot.html LD50 for various snakes<!-- Bot generated title -->]</ref><ref>[http://www.toxinology.com/fusebox.cfm?fuseaction=main.snakes.display&id=SN0520 WCH Clinical Toxinology Resources<!-- Bot generated title -->]</ref><ref>[http://www.toxinology.com/fusebox.cfm?fuseaction=main.snakes.display&id=SN0558 WCH Clinical Toxinology Resources<!-- Bot generated title -->]</ref><ref>[http://www.explorebiodiversity.com/snakes/main/mostvenomous.html Snake Web – The Wild Classroom<!-- Bot generated title -->]</ref><ref>[http://www.kingsnake.com/toxinology/LD50/LD50men.html LD50 menu<!-- Bot generated title -->]</ref><ref>[http://www.kingsnake.com/toxinology/LD50/ld50sc.html LD50 – subcutaneous<!-- Bot generated title -->]</ref><ref>http://www.chm.bris.ac.uk/webprojects2003/stoneley/strength.htm</ref><ref>[http://www.reptileallsorts.com/bites-venom.htm Bites Venom<!-- Bot generated title -->]</ref>
