TitleUnpublished paper, 'On the action of light on the colour of the river sponge (Spongilla fluviatilis)' by John Hogg
Date9 May 1838
DescriptionHogg observes that the green colour of the river sponge is acquired solely through exposure to light, and is lost when the sponge is kept away from a light source. As this does not appear to be the case with Actiniae [anemone] or the Hydra viridis [cnidaria], Hogg suggests that the river sponge is more closely related to algae or fungi than to any animal.

Subject: Zoology / Botany
