Here’s another simple but difficult question that came up this week on Twitter prompted by cephapodologist @Thomas_Clements reaction to a tweet put out by the team behind the E/V Nautilus deep sea rover twitter account which used a popular science fact about vampire squid which read as such:
Did you see it?! We had an extended visit with a Vampyroteuthis infernalis (literally meaning “vampire squid from hell”). Neither a squid nor octopus, this fierce-sounding cephalopod actually fishes for marine snow using two retractable filaments and mucus-covered suckers!
Now, as you may have gathered from the title of this post, the bit I’m interested in is the ‘fact’ about vampire squid being neither an octopus or a squid. It’s a common enough fact you can find out and about in the edutainment and sci-comm resources and there’s something about the trope of telling people that a name we’ve just told them doesn’t mean what it is commonly assumed to which science communicators love. Whether or not ‘not facts’ help with engagement or learning I remain to be convinced.
Thomas, who surely knows his nidamental glands from his accessory nidamental glands, quoted the tweet stating that vampire squid are in fact octopuses. At this point I got involved too possibly disagreeing with him, although even with 280 characters discussions went around in circles. So. Once and for all.
