No bones about them, invertebrates don't have a spine. They proudly wear their skeleton on the outside (or stay wobbly and do not have one at all). With your help, Redmap will be tracking the following invertebrates around Australia. Some of these species may be common along your coastline - but have you spotted any that aren't normally found at your local diving, fishing or swimming spots? Redmap is interested in sightings where these invertebrates have ventured away from their usual home range. You can sort this list by region and name.
