A fact from Halisarca caerulea appeared on Wikipedia's Main Page in the Did you know column on 22 October 2020 (check views). The text of the entry was as follows:

Did you know... that the sponge Halisarca caerulea forms part of a "sponge loop", absorbing large quantities of dissolved organic carbon, and returning the carbon to the sea as detritus?

A record of the entry may be seen at Wikipedia:Recent additions/2020/October. The nomination discussion and review may be seen at Template:Did you know nominations/Halisarca caerulea.

... that the sponge Halisarca caerulea forms part of a "sponge loop", absorbing large quantities of dissolved organic carbon, and returning the carbon to the sea as detritus?
- ALT1:... that the sponge Halisarca caerulea grows very slowly despite filtering large quantities of carbon from seawater?
- ALT2:... that the sponge Halisarca caerulea is bright blue?

Reviewed: Vaxholm Church
Comment: This is a very interesting sponge but it is difficult to explain why in layman's terms in a hook, which is why I have added ALT2.

Starting review--Kev min § 20:53, 3 October 2020 (UTC)[reply]

Article is new enough and long enough. Article is neutrally written, and cite to reliable sourcing. no copyvio issues identified during review. @Cwmhiraeth: in the ecology section it may be helpful to clarify that the sponge is replicating and sloughing the choanocytes specifically, and not all the cells in general.--Kev min § 16:59, 4 October 2020 (UTC)[reply]

No doubt you are right and it is the choanocytes, but it does not actually state that in the sources I used. I was more concerned by the statement that the Caribbean was nutrient-poor, and yet it seems to be rich in carbon, which I would describe as a nutrient. I guess the nutrient-poor bit refers to trace elements or micro-nutrients. Cwmhiraeth (talk) 18:04, 4 October 2020 (UTC)[reply]

@Cwmhiraeth: the paper is free online though researchgate, and the authors were specific that its the choanocytes. They also clarify the terms they are using. Here is the page for the paper.--Kev min § 19:14, 4 October 2020 (UTC)[reply]

@Kevmin: I hadn't realised that and have added the information. The nutrient balance/loop makes more sense now. Cwmhiraeth (talk) 19:41, 4 October 2020 (UTC)[reply]

Awesome, article hooks are all cited and sourced, and reflect the sources accurately. No policy issues are present in the article. nom is good to go.--Kev min § 23:40, 4 October 2020 (UTC)[reply]
