Original: The colour of blood 🩸 Good stuff here. # Science # Scicomm # Biology https:// knowablemagazine.org/content/a rticle/livi
A Knowable Magazine article explains why animal blood comes in different colours, looking at the biology behind pigments such as haemoglobin-based red blood and the blue and green bloods found in some invertebrates. The piece is being shared and recommended by science communicators online, who are praising its accessible explanation of how different blood pigments evolved across the animal kingdom.
Why now: Readers are drawn to surprising biology explaining that not all animal blood is red.
