Title | Unpublished paper, 'On the action of light on the colour of the river sponge (Spongilla fluviatilis)' by John Hogg |
Date | 9 May 1838 |
Description | Hogg 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.
