Why Are There No Male Whalefish?

The video explores the mysteries of deep sea fish families, initially thought to be separate due to distinct characteristics. Through DNA analysis, it was discovered that the whale fish, Big Nose fish, and Tapetail fish are actually one family, known as Sedomymity. This family exhibits extreme sexual dimorphism, with males and females having different adaptations for survival in the deep sea. The video highlights the challenges of deep sea research and the importance of genetic analysis in understanding marine biodiversity.
