When is a giant octopus not a giant octopus?

A new story doing the rounds earlier this week reported on a ‘foolhardy’ dolphin that suffocated whilst trying to eat a giant octopus. You can read the story here at New Scientist. The story is based on a short note paper published in Marine Mammal Science and its one of those nice little papers that describes a rare behaviour to add to the anecdotal record of behaviour between cetaceans and cephalopods. The Marine Mammal Science paper goes into grim detail about how an octopuses arms and suckers can remain active up to an hour after the ‘head has died’ and in this instance the suckers were still firmly to the Indo-Pacific bottlenose dolphin’s larynx, oesophagus and tongue during the autopsy.  The story was circulated fairly widely in the ‘science tabloid’ outlets and news websites however all is not as it seems.

Headline from the New Scientist reporting

Many stories lead with the headline about a giant octopus and some sort of judgement of the dolphin involved- greedy, foolhardy- but the reporting of this story is a nice example of when engineering a clickable headline and story is actually a bit misleading. At its worst we called say this was fake news. But this is exactly the kind of example I like to use when teaching students about the difficulties of striving for readability and accuracy as well as the wonderful complication of language especially when it comes to science. So when is a giant octopus not a giant octopus? Read on to find out. Continue reading

Cephalopod Watch:Weeds of the sea and the <Gene diet

Two bits of cephalopod stuff in the media last week, both of which raised the hackles but for different reasons relating to how the media (in this case mostly online) handles science reporting. I always find this kind of stuff interesting, doubly so since a really interesting talk at NatSCA 2015 Annual Conference where we heard from colleagues at the BBC and science programmers about how documentaries aren’t for those in the know. Both in terms or viewers and critical acclaim, the scientists may hate shoddy science but they aren’t the target audience. This shouldn’t give the media free rein to just report what they like but trying to squeeze complicated, limited and caveated findings into nice black and white narratives leads to more confusion. Things can only be bigger, smaller, disappearing, brand new, oldest, fastest, slowest etc. Biology, (un)fortunately, is rarely that simple.

The first of the bits of news last week was this paper, Global proliferation of cephalopods in Current Biology about estimating cephalopod populations Continue reading
