The Vaquita, also known as the Desert Dolphin, is a rare marine mammal that lives in the Gulf of Mexico of California. Many precautions have been made to protect this dolphin such as prohibiting fishing in the area and creating fishing nets that keep fish and other large sea creatures from getting caught. They have lost half of their population in the past three years.
Something the Vaquita’s can do is have some way of cutting the net. Having blades on its fins can allow it to do so. This would be a good option if fisherman still use standard nets and still do illegal fishing.
