Who"s that in the spotlight? A humpback whale! Known for their haunting songs and acrobatic breaches, these gentle giants were once on the edge of extinction due to whaling and entanglement in fishing gear. Inhabiting oceans and seas across the globe, humpback whales prefer polar waters for feeding; they journey to tropical or subtropical regions for breeding and giving birth. Their diet predominantly consists of krill and small fish, and they employ a unique bubble-net technique to efficiently prey. Thanks to conservation efforts, their population is making a comeback, from around 5,000 in 1966 to an estimate of 135,000 today.
