An early Christmas tree made of 13 different types of diatoms, single-cell algae living in water 🎄
🟢 There may be as many as 2 million different kinds of diatoms; scientists are discovering new species of diatoms each year

🟢 Diatoms come in many different shapes and patterns thanks to their cell walls made of silica

🟢 #Diatoms are indicators of water quality, from pH to nutrient levels

Thank you to 🇩🇪 Anncharlott Berglar holds a PhD in Biology and an MA in scientific illustration. She loves to visualise #nature and #science and make them understandable to everyone. Anncharlott made most of the drawings based on the information presented on and, and was inspired by Ernst Haeckel’s diatom plates.
