The blue whale was abundant in nearly all the Earth's ... blue whales as a separate population, ... whales in 1926. There are an estimated total of 1,000–3,000 ...
World population graph of blue whales. Whaling by humans has existed since the Stone Age. Ancient whalers used harpoons to spear the bigger animals from boats out at sea. [123] People from Norway started hunting whales around 4,000 years ago, and people from Japan began hunting whales in the Pacific at least as early as that. [124]
Because of overhunting, the blue whale population has dropped from what biologists estimate was 200,000 in the 1800s to approximately 20,000 today. They are listed as endangered by the IUCN. Their ...
This is a collection of lists of mammal species by the estimated global population, divided by orders. Lists only exist for some orders; for example, the most diverse order - rodents - is missing. Much of the data in these lists were created by the International Union for Conservation of Nature (IUCN) Global Mammal Assessment Team, which ...
A thrifty study uncovers a wealth of data about one of the world's largest and most elusive species.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [ 8 ] [ 9 ] Estimates on the number of Earth's current species range from 10 million to 14 million, [ 10 ] of which about 1.2 million have been documented and over 86 percent have not yet been described.

Blue whales can reach 100 feet long and weigh up to 330,000 pounds, according to the National Oceanic and Atmospheric Administration.. The ocean giants live in all oceans except the Arctic, NOAA ...
Prewhaling population may be a huge under-estimate. A recent study (2003) gives population estimates for fin and humpback whales far greater than those previously calculated for prewhaling populations. Similar studies have not yet been done for Blue Whales. (Roman, J and S.R. Palumbi. 2003. Whales Before Whaling in the North Atlantic.
