Help marine animals escape hypoxia
in water... and its predators!

You are here

Yes, water has oxygen too!

Marine water has oxygen in it, but it can run out! Marine hypoxia often occurs when humans pollute the water; some animals can swim away like fish, but slow-moving animals, like sea urchins, are not able to move fast enough. Help our hero sergeant major fish escape the oxygen-poor water and save his friends from danger, while not getting eaten by its predators!

You can play with your cell phone, tablet or computer. Have fun!
