Our biology department has been having a lot problems keeping sea urchins alive here in landlocked central PA. Probably mostly from poor keeping, but they seem to be very sensitive to our wide temperature fluctuations (i.e. purple California sea urchins hate PA winters). As a back up we would like to use another organism when our urchins die off, possibly a Ciona species. Does any sea squirt biologists (Jarrett, Miriam?) have a protocol for dissecting gonad our of sea squirts? It is for a development lab. Please leave or a comment or email me (address in top right sidebar).
