'''Belchers havslange''' ([[latin]]: ''Hydrophis belcheri'') er en [[slange]] med et giftigt bid. 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.
Giften er stærk, men 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>{{Cite web |url=http://www.jcu.edu.au/school/tbiol/zoology/herp/Enhydrinaschistosa.PDF |title=Arkiveret kopi |access-date= 8. august 2009 |archive-date=14. februar 2012 |archive-url=https://web.archive.org/web/20120214164331/http://www.jcu.edu.au/school/tbiol/zoology/herp/Enhydrinaschistosa.PDF |url-status=yes }}</ref><ref>[{{Cite web |url=http://www.4to40.com/QA/index.asp?id=631&category=animal |title=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 -->] |access-date= 8. august 2009 |archive-date=13. februar 2008 |archive-url=https://web.archive.org/web/20080213065155/http://www.4to40.com/qa/index.asp?id=631&category=animal |url-status=yes }}</ref><ref>{{Cite web |url=http://www.phcog.net/phcogmag/issue9/11.pdf</ref><ref>[http |title=Arkiveret kopi |access-date= 8. august 2009 |archive-date=29. september 2007 |archive-url=https://web.archive.org/web/2007092812174820070929100647/http://www.phcog.net/phcogmag/issue9/11.pdf |url-status=yes }}</ref><ref>{{Cite web |url=http://www.cfrar.com/venomoussnakes.htm |title=The Center for Reptile and Amphibian Research: The Most Venomous Snakes<!-- Bot generated title -->] |access-date=28. september 2007 |archive-date=28. september 2007 |archive-url=https://web.archive.org/web/20070928121748/http://www.cfrar.com/venomoussnakes.htm |url-status=yes }}</ref><ref>[http://animal.discovery.com/fansites/crochunter/australiazoo/10mostvenomous.html Animal Planet :: Australia Zoo – Venomous Snakes<!-- Bot generated title -->]</ref><ref>[http://{{Cite web.archive.org/web/20080118012414/ |url=http://www.barefootbushman.com/venoms.htm |title=Relative Toxicity of Australian Snakes<!-- Bot genereret titel -->] |access-date=18. januar 2008 |archive-date=18. januar 2008 |archive-url=https://web.archive.org/web/20080118012414/http://www.barefootbushman.com/venoms.htm |url-status=yes }}</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>[{{Cite web |url=http://www.explorebiodiversity.com/snakes/main/mostvenomous.html |title=Snake Web – The Wild Classroom<!-- Bot generated title -->] |access-date= 8. august 2009 |archive-date= 9. januar 2009 |archive-url=https://web.archive.org/web/20090109052230/http://www.explorebiodiversity.com/snakes/main/mostvenomous.html |url-status=yes }}</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>[{{Cite web |url=http://www.reptileallsorts.com/bites-venom.htm |title=Bites Venom<!-- Bot generated title -->] |access-date= 8. august 2009 |archive-date=31. oktober 2006 |archive-url=https://web.archive.org/web/20061031231320/http://www.reptileallsorts.com/bites-venom.htm |url-status=yes }}</ref>
