Recently, the BOW has presented a dozen or more unnamed Lomanotus species and an unnamed Thorunna from the Indo-Pacific. To emphasize our global lack of knowledge, this week I give you an unnamed dorid from the tropical eastern Pacific, on the other side of the Big Pond. The oceans need our protection, before we lose what we don’t even know we have.

Hans with granddaughter Adriana Ivette Cadena (of Tenellia ivetteae fame), at Badwater, Death Valley. At -282 feet (-85.5 m) it is the deepest point on the continental United States, and deeper than Hans, Webmaster Mike, and contributors Dave Behrens or Jan Kocian have ever dove!
