Introduction

Purple-encrusting sponges are probably the easiest sponges to see on Sydney's rocky shores.

Identification

Always a light purple colour, these sponges are covered in small crater-like holes over their surface.

Habitat

Purple-encrusting sponges live on intertidal rocky shores.

Distribution

Purple-encrusting sponges are found in waters around Australia.

Other behaviours and adaptations

Purple-encrusting sponges can be found near the low-tide mark attached to rock surfaces in small, irregular-shaped patches. They are the only sponges common in rock pools exposed to full sunlight.
