In red algae, for example, these proteins occur as pigments. But in this newly discovered group of algae, the phycobiliproteins appear to be contained inside the plastids,

I think there is something wrong about that statement. The fact that phycobiliproteins serve as pigments in red and glaucous algae does not mean that they are NOT found within their plastids. As a matter of fact I think that phycobilisomata which are constructed after pbilips are contained exclusively within red and glaucous algae's plastids as photosynthesis performing organelles.--Draco ignoramus sophomoricus (talk) 15:11, 8 December 2009 (UTC)[reply]

Note that it is not clearly shown yet that biliphytes are photosynthetic, rather they are putatively photosynthetic. This is because fluorescence was seen that could be from phycobiliproteins but it was not chemically shown through HPLC and alternatively could have been from an ingested prey item. In addition, since their discovery they have been named by some researchers as 'biliphytes' rather than 'picobiliphytes' because they are often larger than 2 micrometers in diameter.

Picozoa and Picobiliphyte merge discussion

It looks like the sock puppet @Caftaric: proposed the merge of Picozoa and Picobiliphyte.

Oppose - Unless someone can explain how the photosynthetic Picobiliphytes and the heterotrophic Picozoa are the same thing.Nessie (talk) 15:16, 21 September 2018 (UTC)[reply]

Closing proposal, given the opposition and abscence of support. Klbrain (talk) 22:46, 30 December 2018 (UTC)[reply]

Resolved

@NessieVL:That's a easy question. Cause they were formally identified as photosynthetic algal, and a remnant nucleus of a secondary algal endosymbiont were observed. But recently research rejected it, and find they feeds on very small (<150 nm) organic particles. You can refer to these articals:
