If I was in Tasmania, I wouldn&#8217;t be particularly concerned about any increase in bites from sevengill sharks. This isn&#8217;t the only bite that&#8217;s known, there have been three in the last 13 years in New Zealand, and I&#8217;m also aware of another one in Victoria as well.<\/p>\n<p>David Reilly<br \/>And with the sevengill shark, how do these bites typically happen?<\/p>\n<p>Daryl McPhee<br \/>It&#8217;s generally been on a usual array of water users, so there&#8217;s been a couple on divers, one on a surfer in New Zealand from memory, and a swimmer.<\/p>\n<p>David Reilly<br \/>Right. Okay. So they&#8217;re typically found in Tasmanian waters, or is it unusual to see them?<\/p>\n<p>Daryl McPhee<br \/>No, they&#8217;re typically found in Tasmanian waters. They&#8217;re a temperate water species, so they can be quite abundant at times in Tasmania. But my understanding, what&#8217;s a bit unusual in this instance was they&#8217;re generally more prevalent in the warmer months, in summer. So it was a bit of a surprise to hear of this bite at this time of the year.<\/p>\n<p>David Reilly<br \/>Right. Unusual things happening in Tasmanian waters. The swimmer, I think they were spearing, so they had a sort of a fish spear. Is it possible that that could have attracted the shark?<\/p>\n<p>Daryl McPhee<br \/>Yeah, it is possible. It always changes the risk profile when someone&#8217;s spearfishing. But spearfishing is a popular activity, it&#8217;s occurred over a long period of time in Tasmania. So again, that risk of a bite of a sevengill is low, and they&#8217;re not responsible for any known fatal bites either. They&#8217;re still a large shark. They can get to three metres, but there hasn&#8217;t been a bite that&#8217;s caused fatality, so they don&#8217;t pose that level of risk compared to a white shark.<\/p>\n<p>David Reilly<br \/>All right. So where do they sort of sit in the ecosystem then?<\/p>\n<p>Daryl McPhee<br \/>They&#8217;re opportunistic foragers. They can forage in relatively large schools at times. So they&#8217;re not particularly choosy in what they eat. They&#8217;ll eat other sharks. They&#8217;ll eat lobsters, seabirds, anything that washes into the water.<\/p>\n","protected":false},"excerpt":{"rendered":"Daryl McPheeI think it&#8217;s a very isolated event.
