Snake lunging at a target and biting it multiple times<\/a>Colubrids such as the mangrove snake (Boiga dendrophila) rotate their jaws to tear a gash into their prey.<\/p>\n\u201cOnce they\u2019re biting down they saw or rotate their jaws and cut into the prey, which presumably then gives better penetration of the venom.\u201d<\/p>\n
The researchers also observed some strikes in which the snake reached its target sooner than expected, as the \u201cprey\u201d was moving back and forth. In one case, the fang of a blunt-nosed viper (Macrovipera lebetina) snapped and went flying. \u201cThat was quite dramatic, obviously,\u201d Evans said.<\/p>\n
\u201cThis is likely how fang loss during feeding most often occurs, but this is the first time it has been caught on camera,\u201d the researchers noted in the paper.<\/p>\n
\u201cFangs have previously been found in snake scats, which means fangs often break off during prey penetration, remain stuck in the prey and are swallowed by the snake.\u201d<\/p>\n

The loss of individual fangs was not a problem, Evans said. \u201cThey\u2019re replaced \u2013 the snakes make new fangs throughout their life.\u201d<\/p>\n
Evans said the findings on how different snake species strike would add to \u201cinformation about their conservation and protection\u201d.<\/p>\n
\u201cOnly by knowing their diet and hunting methods can we be confident in that we\u2019re going to put forward protection schemes that are going to be successful.\u201d<\/p>\n
The study\u2019s lead author, Dr Silke Cleuren who is also of Monash University, tested the snakes at Venomworld, a venom production institution on the outskirts of Paris.<\/p>\n
Dr Alessandro Palci of Flinders University, who was not involved in the study, said the research \u201cfills gaps in our knowledge of snakes\u2019 striking behaviour\u201d.<\/p>\n
\u201cThe differences in behaviour that have been reported for viperids, elapids, and colubrids correlate well with what we know about their fang anatomy,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"Venomous snakes must strike fast to sink their fangs in prey before they startle \u2013 as quickly as…\n","protected":false},"author":2,"featured_media":235288,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[64,63,128,338],"class_list":{"0":"post-235287","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-wildlife","8":"tag-au","9":"tag-australia","10":"tag-science","11":"tag-wildlife"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/235287","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=235287"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/235287\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/235288"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=235287"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=235287"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=235287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
