Genomic research on blue whale carcasses revealed surprising findings about the North Atlantic population, showing less inbreeding and more genetic variation than expected despite a history of industrial whaling. The study, published in Conservation Genetics, suggests that the long reproductive cycle of blue whales may have prevented a genetic bottleneck. With fewer than 3,500 adult blue whales remaining in the North Atlantic, the findings provide hope for the conservation of this endangered species.

Fossils of an extinct marine mammal, Perucetus colossus, recently discovered in Peru suggest that it may have weighed up to 340 metric tons, challenging the blue whale's status as the largest animal ever. The massive creature, resembling a manatee, has compelled scientists to reconsider how animals can grow to such gigantic sizes. However, some experts remain skeptical of the estimates and believe more fossils are needed before declaring a new heavyweight champion. The discovery highlights the various ways in which whales can evolve into giants and raises questions about the diet and feeding habits of this ancient leviathan.
