I thought you would like to see another yard art I spotted on my daily bike ride. This one is a little less fearsome than yesterday's yard art so I could get even closer.
It must be a sea turtle. You can see the barnacles on his shell.
Green sea turtles can stay under water for as long as five hours even though the length of a feeding dive is usually five minutes or less. Their heart rate slows to conserve oxygen: nine minutes may elapse between heartbeats.
