Okay - here goes.........
According to the International Whaling Commission, it is very hard to get reliable numbers for creatures that spend the bulk of their lives underwater in deep oceans, but their estimates are roughly.....
Blue Whales.......1,150 - 4,500
Humpback Whales.... 75,000 or so
Minke Whales.......in excess of 1,000,000
Now I don't care who you are, THAT ain't endangered.
You think that's not "endangered"
Now I don't care who you are, THAT ain't endangered.

Until the 1990s, only one species of minke whale was recognized, the Antarctic Minke Whale B. bonaerensis being regarded as conspecific with the Common Minke Whale B. acutorostrata. Most of the scientific literature prior to the late 1990s uses the name B. acutorostrata for all minke whales including Antarctic Minke Whales. Since 2000, the International Whaling Commission (IWC) Scientific Committee (SC) has recognized Antarctic Minke Whales as the separate species B. bonaerensis, while all northern hemisphere minke whales and all southern hemisphere "dwarf" minke whales are regarded as B. acutorostrata (IWC 2001). This has been followed by management and treaty bodies, such as Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Balaenoptera bonaerensis
(1978–84) 645,000
(1985–91) 786,000
(1991–2004) 338,000

The IWC SC conducted a major assessment of Antarctic minke whales in 1990, and a population estimate of 760,000 was adopted, based on results of the IDCR surveys conducted in the seasons 1982/83 through 1988/89 (IWC 1991). Results of subsequent surveys indicated lower abundances leading the Committee to conclude in 2000 that the estimate of 760,000 was no longer a valid estimate of current abundance. The Committee has to date (January 2007) been unable to determine whether the apparent decline was real or artifactual. The Committee considered the two most likely confounding factors to be: (i) a reduction in sighting efficiency (e.g. due to smaller school sizes and possibly less experienced observers) and (ii) changes in ice extent, such that fewer whales occurred in surveyable open water.
