Solar powered sea slugs shed light on search for perpetual green energy

In an amazing achievement akin to adding solar panels to your body, a
Northeast sea slug sucks raw materials from algae to provide its
lifetime supply of solar-powered energy, according to a study by Rutgers
University-New Brunswick and other scientists.

“It’s a remarkable feat because it’s highly unusual for
an animal to behave like a plant and survive solely on photosynthesis,”
said Debashish Bhattacharya, senior author of the study and
distinguished professor in the Department of Biochemistry and
Microbiology at Rutgers-New Brunswick. “The broader implication is in
the field of artificial photosynthesis. That is, if we can figure out
how the slug maintains stolen, isolated plastids to fix carbon
without the plant nucleus, then maybe we can also harness isolated
plastids for eternity as green machines to create bioproducts or energy.
The existing paradigm is that to make green energy, we need the plant
or alga to run the photosynthetic organelle, but the slug shows us that
this does not have to be the case.”

Talk about a big bite!

Here, a white-spotted rose anemone clings to and attempts to ingest a
moon jelly in Monterey Bay National Marine Sanctuary. Although the
jelly is twice the size of the anemone, most of the jelly is water, so
it’s not an impossibly large meal. While moon jellies are usually open
ocean species, sometimes oceanographic conditions bring them closer to
shore – and into the mouths of creatures like this anemone. (Photo: Steve Lonhart/NOAA)

Fish Using Jellyfish as Shelter

Jellyfish serve as a habitat to many ocean creatures…
Jellyfish play a critical role in the lives of different marine
creatures. While they are used as a direct food source for many, some
use them as shelter (juvenile fish), some as a means of travelling from A
to B and some have a combined interest of travelling while snacking on
the microscopic parasites attached to the Jellyfish.

These symbiotic relationships are very intricate and are being
investigated by scientists. [source]
