[18:15:36] adriennecopeland leaves the room [18:15:52] My guess is that that first medusa and the Aulacoctena will be most in need of processing. The first because it was captured so long ago. The latter because deep sea ctenophores can be so delicate. [18:16:31] That ctenophore could have juveniles within, so keep an eye out for them when imaging. Best of luck!
