Editing Antarctic krill (section)

===Escape reaction===
Krill use an [[escape reaction]] to evade [[predator]]s, swimming backwards very quickly by flipping their rear ends. This swimming pattern is also known as [[Caridoid escape reaction|lobstering]]. Krill can reach speeds of over {{convert|0.6|m/s}}.<ref name="Kils82">{{cite book |author=Uwe Kils |url=http://www.ecoscope.com/biomass3.htm |title=Swimming behaviour, swimming performance and energy balance of Antarctic krill ''Euphausia superba'' |series=BIOMASS Scientific Series |volume=3 |pages=1–122 |year=1982 |access-date=2010-03-26 |archive-date=2002-12-13 |archive-url=https://web.archive.org/web/20021213053241/http://ecoscope.com/biomass3.htm |url-status=dead }}</ref> The [[Induction period|trigger]] time to optical [[stimulus (physiology)|stimulus]] is, despite the low temperatures, only 55&nbsp;[[millisecond|ms]].
