Marine reptiles include turtles, seasnakes and crocodiles. Some, like turtles, spend most of their life in water but return to land to lay their eggs. With your help, Redmap will be tracking the following reptiles 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 reptiles have ventured away from their usual home range. You can sort this list by region and reptile name.
