Cynthia D. Trowbridge Sacoglossan Costasiella usagi

IkeBe Ph Thank you Cynthia D. Trowbridge!

Cynthia D. Trowbridge The green alga is Avrainvillea... you should have many species of Costasiella in your area but they are poorly described. The present one is very obvious but others such as C. kuroshimae is quite controversial.

Andre Snoopy Montenegro Please ID found at 5 meters around 1 cm size Dauin Philippines .

Andre Snoopy Montenegro thank you Jeff!

Andre Snoopy Montenegro different from Costasiella kuroshimae right?

Frank Krasovec Costasiella kuroshimae taken in Feb 2012 Dauin PHL: http://wetlens.smugmug.com/Underwater/Philippines/nudibranch/21852522_Cc5XXV#!i=1742976287&k=PVLPHFq

Cynthia D. Trowbridge very different from C. kuroshimae species complex. The Indo-Pacific is a hotspot of Costasiella speciation.

Anna Nudi Burn Very cool nudi!

Cynthia D. Trowbridge sacoglossan, not nudibranch :-)

Anna Nudi Burn My bad! - Very cool sacoglossan :-D
