3. Blue Whale
Up next in our list of longest animals in the world is the blue whale which is the largest marine mammal in the world. Although on average it measures about 98 feet (30 meters) in length, one individual caught back in 1930 measured 108.2 feet (33 meters). Most of the individuals caught measuring over 30 meters until 1949 were caught in the Southern Ocean. The Guinness Records notes a female found in 1909 measuring as much as 33.58 meters.
Until the beginning of the twentieth century, blue whales, much like all other species, were abundant. In the past century, however, they’ve been hunted almost to extinction by whalers. The blue whale is currently marked as “endangered”.
