The Fin Whale is a baleen whale, and is the second largest whale in the world (the blue whale is the largest). Adults can range in length up to 24 m in the Northern Hemisphere and 27 m in the Southern Hemisphere, weight ranges from 1800 to 2700 kg (4000 to 600 lbs) (Folkens 2002). It is very sleek and slender in appearance with a v-shaped, pointed head and distinctive colouration--it is dark above (black or dark brownish-gray) and white below, with asymmetrical head colour (lower left jaw is dark, lower right jaw is white), light-gray chevrons on the back of the head, and streaks or swirls of ligher colour reaching up from the belly (Jefferson et al. 2008). It has 260-480 gray to black (often striated/fringed) baleen plates on each side--plates on the right side are often lighter--and 50 to 100 long throat plates (Jefferson et al. 2008).
