typhlonectes:

The ROV Tiburon photographed a Granelodone octopus perching on a
lava pillar at the South Cleft of Juan de Fuca Ridge, off the coast of
Washington, USA.

This isn’t the only time MBARI has come across a Granelodone
octopus brooding eggs. MBARI first  discovered a female brooding eggs,
much like the one in this photo in May of 2007. Over the subsequent four
and a half years, MBARI returned to the
same spot to find the female there, protecting her eggs as they
developed. When they returned in October 2011, the female was gone and
the eggs were empty. Brooding eggs is thought to have evolved as a way
to increase survivorship of young. More time in the egg results in more
fully developed young when they finally hatch.
