Victorella pavida

Victorella pavida or trembling sea mat is a species of bryozoans found in shallow waters of low or fluctuating salinity, such as lagoons and estuaries. In summer (the growing season) it can have the appearance of velvet. The zooids may be from 0.3 mm to 1 mm in length.[1] They live in colonies underwater attaching to stones. They feed using tiny hairs attached to their crown of tentacles to catch tiny particles flowing through the water, also known as "filter feeding".

gollark: So it appears that my indexer is actually bottlenecked by database I/O or something. This is fairly troubling!
