All dharma agrees at one point

Twenty years of footage
before anyone knew what it was.

Living at depths between 3,300 and 13,100 feet,
it swims through the ocean's midnight zone,
deep below the surface —
the first nudibranch species found
living in the deep water column.

Its translucent body
protects it from being seen
makes it invisible
by predators.

It doesn't look like the others.

Although it feeds in a similar way
to the lion's mane nudibranch
and the veiled nudibranch,
these species are only distantly related.

What was not measured:
the twenty years before a name,
before the right family neighborhood
could be found.

The hood opens the same way regardless. It has never heard of the others.
