==Description== [[File:Histoire naturelle des poissons (10438834583).jpg|thumb|The albacore's pectoral fins can be longer than 30% of the fish's total length.<ref name=fishbase/>]] The albacore has a streamlined, fusiform body with a conical snout, large mouth, and big eyes. Its body is dark blue dorsally, shades of silvery white ventrally, and covered by small scales.<ref name=fao/> The [[pectoral fins]] begin slightly before the first [[dorsal fin]] and extend well beyond the front of the [[anal fin]], usually as far as the second dorsal finlet, often as long as 30% of the fish's total length. Like the fish's body, the fins are dark blue on top, but change to a medium yellow color on the underside. They are markedly shorter in fish under {{convert|0.5|m|ftin|abbr=on}} in length, often resulting in confusion with ''[[Thunnus obesus|T. obesus]]'' juveniles, which also have long pectoral fins, though these are rounded at the tips where the albacore's taper to a point.<ref name=fishbase/> The first dorsal fin is a deep yellow and the second, which is smaller than the first, is a light yellow, as is the anal fin. It has 7β9 dorsal finlets and 7β8 anal finlets, dark blue and silvery white in color respectively, matching the part of the fish's body they are on. The [[caudal fin]] is also silvery white.<ref name=wash>{{cite web |url=http://wdfw.wa.gov/fishing/tuna/ |title=Fishing & Shellfishing: Albacore Tuna |website=Washington Department of Fish & Wildlife |access-date=2013-10-25 |archive-url=https://web.archive.org/web/20171224222151/http://wdfw.wa.gov/fishing/tuna/ |archive-date=2017-12-24 |url-status=dead }}</ref><ref name=fao>{{cite book |last=Collette |first=Bruce B. |author2=Cornelia E.
