Here, we present estimates on the metabolic and energetic demands of this cold-water deep-sea giant. The estimated mass-specific routine metabolic rate for the colossal squid at 1.5\u00b0C was 0.036\u00a0\u00b5mol O<jats:sub>2<\/jats:sub>h<jats:sup>\u22121<\/jats:sup>g<jats:sup>\u22121<\/jats:sup>and the projected daily energy consumption (45.1 kcal day<jats:sup>\u22121<\/jats:sup>) was almost constant as a function of depth in the nearly isothermal Antarctic waters. Our findings also indicate the squid shows a slow pace of life linked with very low prey requirements (only 0.03\u00a0kg of prey per day). We argue that the colossal squid is not a voracious predator capable of high-speed predator\u2013prey interactions. It is, rather, an ambush or sit-and-float predator that uses the hooks on its arms and tentacles to ensnare prey that unwittingly approach.<\/jats:p>","DOI":"10.1017\/s0025315409991494","type":"journal-article","created":{"date-parts":[[2010,4,20]],"date-time":"2010-04-20T10:20:16Z","timestamp":1271758816000},"page":"1375-1378","source":"Crossref","is-referenced-by-count":26,"title":["Slow pace of life of the Antarctic colossal squid"],"prefix":"10.1017","volume":"90","author":[{"given":"Rui","family":"Rosa","sequence":"first","affiliation":[]},{"given":"Brad A.","family":"Seibel","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2010,4,20]]},"reference":[{"key":"S0025315409991494_ref33","doi-asserted-by":"crossref","first-page":"323","DOI":"10.1007\/s00300-001-0343-x","article-title":"Distribution of cephalopods recorded in the diet of the Patagonian toothfish (Dissostichus eleginoides) around South Georgia","volume":"25","author":"Xavier","year":"2002","journal-title":"Polar Biology"},{"key":"S0025315409991494_ref14","doi-asserted-by":"publisher","DOI":"10.2307\/4803"},{"key":"S0025315409991494_ref17","volume-title":"The brains and lives of cephalopods","author":"Nixon","year":"2003"},{"key":"S0025315409991494_ref11","doi-asserted-by":"crossref","first-page":"815","DOI":"10.1007\/s00227-001-0752-y","article-title":"Behavior of midwater fishes under the Antarctic ice: observations by a predator","volume":"140","author":"Fuiman","year":"2002","journal-title":"Marine Biology"},{"key":"S0025315409991494_ref29","doi-asserted-by":"publisher","DOI":"10.2960\/J.v22.a20"},{"key":"S0025315409991494_ref24","doi-asserted-by":"publisher","DOI":"10.1086\/591950"},{"key":"S0025315409991494_ref6","first-page":"324","article-title":"Cephalopoda in the diet of sperm whales of the southern hemisphere and their bearing on sperm whale biology","volume":"37","author":"Clarke","year":"1980","journal-title":"Discovery Reports"},{"key":"S0025315409991494_ref27","doi-asserted-by":"publisher","DOI":"10.2307\/1542531"},{"key":"S0025315409991494_ref30","doi-asserted-by":"publisher","DOI":"10.2960\/J.v42.m652"},{"key":"S0025315409991494_ref16","first-page":"379","article-title":"Growth and energy budgets of large baleen whales from the southern hemisphere","volume":"5","author":"Lockyer","year":"1981","journal-title":"FAO Fisheries Series"},{"key":"S0025315409991494_ref8","first-page":"662","article-title":"Morpho-ecological aspects of the study of Antarctic squids","volume":"49","author":"Filippova","year":"1991","journal-title":"Bulletin of Marine Science"},{"key":"S0025315409991494_ref19","doi-asserted-by":"publisher","DOI":"10.1016\/S0967-0645(04)00087-6"},{"key":"S0025315409991494_ref13","doi-asserted-by":"publisher","DOI":"10.3354\/meps07035"},{"key":"S0025315409991494_ref15","unstructured":"IRICS (2009) The International Research Institute for Climate and Society.
