50 cm

Distribution

Finger Sponges are found southwards from Western Australia to the central New South Wales coast.

Habitat

Finger Sponges live in coastal waters and on subtidal rocky reefs.

Other behaviours and adaptations

Sponges are sessile (unable to move around) and they attach themselves to rocks using a 'holdfast'. This is a specialised tissue for clinging onto rocks that looks a little like the roots of a plant. During storms sponges can be dislodged and washed up on beaches where they are commonly found.
