This sponge is recognised by its hand shape or finger-like projections.
The Finger Sponge's colour varies from dull orange to brown, grey and cream. Its surface is covered in large holes giving it a honeycomb appearance.
Finger Sponges live in coastal waters and on subtidal rocky reefs.
Finger Sponges are found southwards from Western Australia to the central New South Wales coast.
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.
