Gillanders noted that after the El Niño and La Niña phenomena of 1997-98, for instance, warm Pacific waters apparently affected whole populations of Humboldt squid (also known as jumbo flying squid): unusually large Humboldts were found in large numbers swimming off Mexico, Peru and Chile.
The squid, which live longer than most other squid (two years, rather than one), can grow to nearly 5ft: after El Niño, they were found weighing between 25lb and 88lb.
More than a decade later, the long-lived squid were found to have adapted to the 2009-10 El Niño by moving 100 miles north of their usual territory. Others moved into the open ocean and began breeding much earlier than normal.
