Marks sea star sampling device (Updated with underwater video)


Sea stars are melting along our coast. So Mark made this super cheap device to take samples. We are testing it in the ocean today. Update: I had problems with the motors in salt water I think so didn't get to test in the ocean and did a tank test instead.


Interesting and ingenious. Nice work. However, are you sampling the sea star tissue? Not sure what exactly the use case is.


Yes that would be the idea, and if that failed then it's a general sucker device.


Do the plastic parts that snap back stay on the device or are they lost and need to be added later on?
