Concerning message #22819:

Dear Bill

first of all, thanks for your feedback and maintain such a useful and interesting site. Your explanation about the sudden appearance of this species is another interesting alternative

I was looking for little more on photos in this forum as well on other websites, and this animal seems to me very similar to Pleurobranchaea maculata (?). In relation to P. inconspicua I found a record from Argentina in Muniain et al (2006). That work has very good color photos of living animals and I found it freely available at

  • Muniain, C., N. E. Ardila, et al. (2006). Pleurobranchaea inconspicua Bergh, 1897 (Opisthobranchia: Pleurobranchidae): Redescription and distribution from Argentina and Colombia. Bonner zoologische Beiträge 55: 291-300.

Any news I have on this animal in the future I´ll add here.
Thanks again.

Best regards
Nahuel Farias

Dear Nahuel,

I should have noted that reference. It does indeed have some nice photos. Your animal does look quite like P. maculata but without anatomical comparisons we can't be sure. I look forward to more news from you and if we are lucky, perhaps someone familar with the South American fauna may have some suggestions.

Best wishes,
Bill Rudman
