Pulsing Poralia Jelly
Trailing svelte stinging tentacles, the Poralia rufescens jelly drifts through the deep sea as an unseen predator. As red light filters out with depth, an opaque reddish bell blends in.
The Channel Islands National Marine Sanctuary (CINMS) is one of the agencies tasked with the protection of deep-water habitats, commercially important species, and deep sea coral ecosystems around the islands, yet lacks a detailed understanding of the distribution, abundance, and condition of the resources within the Sanctuary. Less than 50% of the seafloor within the CINMS boundaries has been mapped by high-resolution sonar, and the 2016 Nautilus expedition to the same region worked to cut this knowledge gap nearly in half.
