Scientific name: Patiriella vivipara
Distribution: endemic to south eastern Tasmania
Description: This small orange-yellow seastar has a maximum arm radius of 15mm. It is pentagonal in shape and is one of the smallest seastars found
in the world.
Habitat: sheltered rocky shores, low intertidal zone
Ecology: Live-bearing seastars are grazers, feeding on the microscopic algae growing on rocks in the intertidal zone. They are slow moving and occur only in sheltered bays where the wave action will not dislodge them.
