Marks sea star sampling device (Updated with underwater video)


#1

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.



#2

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


#3

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


#4

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