Siphopteron quadrispinosum, Gosliner, 1989

Cynthia reports periodic blooms of what is believed to be Siphopteron quadrispinosum in the Honokohau Harbor area. Depth sightings range from 20 to 100 ft. Cynthia's photo is great! Wonder what this guy would look like in High Definition Video?

On Bill Rudman's Sea Slug forum , and I quote:

"...Hawaiian animals did not have the orange-red along the margin of the posterior shield but the parapodia had a white margin..."

This description sure fits Cynthia's animal!

Getting a picture like Cynthia's is a real challenge when it comes to super small subjects. Take heart readers, it can be done!
