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.
The global blue whale population is estimated to be 5,000–15,000 mature individuals and 10,000–25,000 total as of 2018. By comparison, there were at least 140,000 mature whales in 1926. There are an estimated total of 1,000–3,000 whales in the North Atlantic, 3,000–5,000 in the North Pacific, and 5,000–8,000 in the Antarctic.

The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. ... the blue whale population has dropped from what biologists estimate was 200,000 in the 1800s to ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
Whale skulls have small eye orbits, long snouts (with the exception of monodontids and ziphiids) and eyes placed on the sides of its head. Whales range in size from the 2.6-metre (8.5 ft) and 135-kilogram (298 lb) dwarf sperm whale to the 34-metre (112 ft) and 190-metric-ton (210-short-ton) blue whale.
The blue whale population was drastically reduced, almost driving it to the edge of extinction, after commercial whaling started seeking whale oil. Such hunting was made illegal in 1966.
Volunteers for Ocean Count observe whales from Oahu, Molokai, Kauai and the Big Island, while volunteers for the Great Whale Count observe whales from Maui and Lanai.
