Doctoral dissertation cover

Illustration for front and back cover of the Phd thesis by Alberto Hernández González (Universidad de Vigo), who studies the diet of cetaceans from the Northwest of the Iberian Peninsula and analyzes micro and macroplastics in their stomachs. For this cover I have illustrated the main cetacean species studied: common dolphin (Delphinus delphis), striped dolphin (Stenella coeruleoalba), bottlenose dolphin (Tursiops truncatus) and porpoise (Phocoena phocoena); feeding on a school of fish that contains remains of plastics and microplastics.
