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.|
