Spongilla

Spongilla was first publicly recognized in 1696 by Leonard Plukenet and can be found in lakes, ponds and slow streams.

[3] Using their ostia and osculum these sponges filter the water for various small aquatic organisms such as protozoans, bacteria, and other free-floating pond life.

[4] Sponges of the genus Spongilla partake in symbiotic relationships with green algae, zoochlorellae.

[4] Spongilla was used by John Hogg in the 19th century to attempt to justify a fourth kingdom of life.

Gemmules are highly resistant buds that can live dormant for extended periods of time.
