The Blue Whale: Giants of the Ocean Facing Extinction
The blue whale (*Balaenoptera musculus*), the largest mammal on Earth, once thrived with an estimated population of 275,000 before 1910. Today, only 10,000-14,000 remain, with decreasing numbers in areas like the Gulf of Mexico. Classified as endangered, these massive creatures can reach lengths of 100-120 feet and produce calls up to 188 decibels, audible over hundreds of miles. They primarily eat krill and give birth to calves weighing up to 16,000 pounds. The main threats include hunting for meat and blubber, highlighting the urgent need for legal protections against whaling.
