Introduction: Yellowfin tuna (Thunnus albacares) are a large and superb gamefish found near the surface. Their fins can be folded close to their bodies or tucked into grooves. This makes for excellent sprinting. The body is mostly covered with small scales and the fins are well-developed. Thunnus is an ancient name for 'tuna' and albacares refers to their 'bright yellow fins'.
