Their small size allows them to navigate within crevices and grasp onto algae and small invertebrates.
Asterina starfish are considered to be fascinating creatures due to their ability to regenerate lost body parts. If portioned, each piece has the potential to develop into a whole new individual, making them remarkable for their regenerative capabilities.
In conclusion, Asterina is a genus of starfish characterized by their small, star-shaped bodies. They inhabit various marine environments and display vibrant colors. These starfish play an important role in marine ecosystems, serving as both predator and scavenger, and possess impressive regenerative abilities.
