Jellies found!

At a depth of approx. 400 m, a vertical daylight tow brought up 10 large Periphylla jellies, and 1 small medusa. From here, various morphological measurements were noted down, and tissue removed for laboratory analysis post-cruise. 

Jellies being hauled to the surface using the net constructed by Leon Pedersen. 
Periphylla are covered in red pigment, porphyrin, which degrades when exposed to light, killing the jellies. 
Periphylla can reach considerable sizes, and weigh up to a kilo.
