Don’t get me wrong this is pretty freakin’ sweet, but echinoderms are not the only large Antarctic sea creatures.
But this is way cooler…
That is Syrinx aruanus, the Australian Trumpet, described by Linneaus in 1758. They are found Northern Australia and Eastern Indonesia and can reach sizes of about three feet in length (those above are on the smaller side). And yeah they’re predators.
And surely if we’re playing the size card, the colossal squid pisses all over anything the echinoderms can put forward?
Damn, now THAT”S a gastropod!
