Makes it's own chlorophyll?[edit]

Life cycle[edit]

Frank Ryan outlines in the book 'Virolution' (new edition: ISBN-10: 0007315120, chapter1, page 9) the life cycle of Elysia chloritica: - larvae search for one specific alga (Voucheria litorea), when found they attach firmly to it - the larvae then complete their metamorphosis to tiny slugs - the slugs immediately start to feed on the alga and manage to separate the chloroplasts and store them into specialized cells lining their guts - the gut expands, branching out into various channels all over the body, so that the chloroplasts end up in a confluent layer immediately beneath its skin - the slug than abandons its mouth to become exclusively solar powered for the rest of its life - finally the slug lays its eggs and then dies with symptoms of a severe virus attack

Example for Aggressive Symbiosis?[edit]

Frank Ryan argues in the book 'Virolution' (new edition: ISBN-10: 0007315120, chapter1, page 9) that Elysia chloritica is a prime example of the so called 'aggressive symbiosis' between the slug and an endogenous retro-virus. The virus helped to transfer key genes from the alga and thus helped the slug to enter a life without the need to eat. At the same time the virus culls the complete adult population of the slugs after they have been laid their eggs.

Feeding section[edit]

I find the section on the Feeding mechanism of the Elysia chlorotica unclear. First it says that the slug is capable of assimilating and using the chloroplasts of the algae Vaucheria litorea for it's self. Next there is a large technical paragraph (about the expreience of Sven Gould) (There are no references about this) which says that slugs that can use chloroplasts do not seam to have any advantage as compared to the ones that can not. Does Elysia chlorotica feed through photosynthesis? — Preceding unsigned comment added by Sethyvenatem (talkcontribs) 15:16, 6 May 2014 (UTC)


For the life cycle section, it could use more information, most of the information is about feeding, while the other sections lack the amount of attention that this section does. This article could also talk about any other uses for the chlorophyll besides for feeding purposes. This article could also talk about how the slug came about getting this unique ability. — Preceding unsigned comment added by Larentap (talkcontribs) 02:17, 1 October 2014 (UTC)


Cannot find a definition of the word Elysia, so saying Elysia chlorotica have a typical elysiid shape is self-referential. I suspect this may come from the source's having confused it with the geometric three-dimensional shape ellipsoid. If it come from Elysium or the Elysian Fields (Ancient Greek: Ἠλύσιον πεδίον, Ēlýsion pedíon) that is no help, for Elysian is not itself Greek, but of unknown origin and meaning. That may indeed have a bearing on the selection of the name, but without a better source, the simplest move would be to change elysiid to ellipsoidal. —Pawyilee (talk) 08:17, 7 February 2015 (UTC)
