"Blue Echoes" delves into the lives of Mexican shark fishermen, known as "tiburoneros." The project captures the harsh realities and inherent dangers these fishermen face daily as they venture into the Pacific Ocean to catch sharks. Vespignani's immersive approach involved spending extensive time with the tiburoneros, documenting their strenuous routines and the violent nature of shark hunting, which often involves using makeshift weapons like iron baseball bats. Through this series, Vespignani sheds light on the complex relationship between humans and nature, emphasizing themes of survival, tradition, and the socio-economic factors driving such perilous livelihoods.
