Jumbo Squid Migrate, Too

I can’t pass up a quick note on vertical and horizontal migrations of jumbo squid, also called Humbolt squid, as reported on at Deep Sea News. The study used electronic tagging to track the cephalopods.

W.F Gilly and colleagues tagged seven of the animals with pop-up satellite transmitters over the course of the last few years, and they report their latest findings in a new feature article at Marine Ecology Progress Series. The results show that jumbo squid spend most of the day deeper than 250m, diving repeatedly into a midwater hypoxic zone called the oxygen minimum layer, where the oxygen concentration is less than 5% of surface values.



  1. If you are interested in giant and colossal squid, Te Papa will host and webcast the dissection of 4 giant and 2 colossal squid starting Sunday 27 April. More info can be found on our website: and of course, on our blog :)
