In the 1980s, thousands of humpback whales were slaughtered in Brazil for their blubber.
A few decades ago, a population of only 300 to 500 humpback whales survived in the country, scientist Jose Truda Palazzo, who works at the Humpback Whale Institute in the state of Bahia, told the news agency.
Humpback whales have grown to about 30,000 in Brazil after being decimated in the 80s.

The effort to track the whale population is supported by "citizen scientists," non-professionals with a passion for science who support the work of the scientific community.
