Ja, it's true. Weighed it a couple of days back, 1st on a pellet, 300kg. The pellet weighed 46kg, giving us a 254kg squid. It's coming in at 5.7m, but the two inordinately long tentacles are missing (just a couple of metres of tentacle base present). We've easily lost 2 x 7-8m lengths of tentacle (14-16m combined tentacle length), and a couple of bits of arm, that would, if complete, take this animal over the 275kg maximum I maintain for the female of the species (the recent specimen would have been 280-285kg, if intact); the 275kg specimen was completely intact!!
It really is a monster!! It's total length would have been ~ 14-15m, if intact. Unfortunately the 300kg figure was picked up - hence my dwelling on it - but you can imagine the absolute ballsup there would have been if the press tried to explain pellet weight, or do arithmetic (too many words, confusion ....for such a small piece)!
It's back in the freezer now and will be pulled out for more detailed 'work' in October.
There are, of course, the '20m' specimens recovered from NZ back in the 1880's, and the numerous reports of 1-ton giant squid out there, but pleeeeeeeze let's not have that BS discussion ever again! They are always estimates!! And the 1880's NZ specimens were paced (and this is written in the old "Transactions of the Royal Society of New Zealand" papers in which they were described, and are ex sperm whale stomach contents, regurgitated under stress [harpoon], partially digested, and with tentacles stretched like rubber bands).
To indicate how hard it is to estimate the weight of these things - I looked at the recent lump and guessed 175kg. I was way out (and the scales we're using are horrifically expensive, with 3 separate measurements on the scales, with pellet, giving 300, 300 and 300kg)!!! It is unfortunate that the weight wasn't 299 or 301kg, because 300 on the nose [with pellet] makes it sound like an estimate.
I'd like to hear of any truly heavier specimen!! That's # 119 to go on the scales - and that's a lot of squid.
