#100daysofseahorses

 #the100dayproject

Over on Instagram I've created #100daysofseahorses over 100 days,

learning more about all the different species of seahorses. 

 

Using data from the IUCN Redlist, creating from an artistic, aesthetic viewpoint, not a particularly scientific one. I’m hoping to understand more about seahorses while highlighting their vulnerabilities. Seahorses have fascinated me for a long time, with horse-like heads, tails like monkeys, eyes that move independently and the amazing ability to change colour like chameleons.
