Glaucus atlanticus

Forster, 1777


Jon Chamberlain Diving cancelled for the day due to a huge amount of portugese-man-of-war jell fish being blown in by strong winds but the pay off is seeing the spectacular Glaucus atlanticus that feeds on them.

Charlotte Bolton Gorgeous!

Sarah Bowen WOW!!!

David Ennew I found these little critters washing up on the Beach at Mudjimba today .Perhaps washed away from Old Woman Island.Most appeared to be alive in the water but they perish quickly on the sand .These ones are alive.

Carl-Johan Nilsson Glaucus atlanticus.

Gary Cobb These little guys are Glaucus marginatus. The cerata on end of the 'arms' are in multiple rows. G. atlanticus has one row and are larger.

David A Mullins These nudibranchs can be found washed up on the beach together with their prey - bluebottles following a period of strong onshore winds. They drift in the open ocean with the bluebottle swarms. They are able to utilise some of the nematocysts (stinging cells) of the bluebottles for their own defence transporting them undischarged internally to sacs at the tips of their cerata.

Julian Galeano un gusto hacer parte ahora del grupo ! este animalito despertó todo mi interés en los nudibranquios ! hermoso

Oriol Domingo realmente precioso, pero lo de toquetearlo me parece un horror.... (supongo que ni l foto ni la mano son tuyas...)

Jol Falcés Es brutalmente precioso. No me extraña que haya despertado tu interés.

Jol Falcés Se trata de un Glaucus Atlanticus. Es un nudibranquio que vive boca abajo sobre la tensión superficial del agua del mar y logra la flotabilidad positiva gracias a una bolsa de aire que tiene en el estómago. Se alimenta de medusas venenosas, entre otras de la la Carabela Portuguesa.

Julian Galeano por supuesto la mano no es mía (: ; si me entere algo acerca de su hábitat y comportamiento , puede llegar a ser venenoso despues de comerse una carabela portugesa almacenando su veneno en la punta de sus patitas

Oriol Domingo ...pues ya le vale al modelo de manos!!!

Jaime Romero ¿..............................?

Vinicius Padula Glaucus cf. atlanticus. One planktonic nudibranch species. Marvellous photo Jaime Romero! There are some researchs going on this species right now.

Jaime Romero Gracias Vinicius.

Lucas CerCur Si te encuentras alguno mas, me vendría muy bien que lo colectaras.

Felipe Martins meu sonho de trabalho <3 pena que nao tem registro para o Ceará ;/

Vinicius Padula Felipe Martins, pode não ter registro, mas nada impede dessa espécie aparecer por aí ;) Tem que ficar de olho quando aparecerem caravelas, das quais eles se alimentam.

Gary Cobb Why Glaucus cf. atlanticus? This is Glaucus atlanticus. Have new things been discovered?

Jon Chamberlain Great find! One of the most amazing nudibranchs. When we found a bunch of them on Hoga, Indonesia it sparked a great debate as to whether there were 2 species: Glaucus atlanticus and Glaucus pacificus (based on where they are found). Only Glaucus atlanticus exists in WoRMS and I can only find scant reference to G. pacificus (nothing published). Anyone know where this rumour might have originated from? Vinicius - Can you post up some links to the latest research you know about, I'd be interested to know more.

Marlon Delgado sonho de encontrar no RN³
