News: Scientists have discovered that a bacterium caused the 2013 starfish die-off, which killed about 5 billion sea stars by causing sea star wasting disease, where their limbs fall off and bodies break down.
About Starfish
- Starfish are marine animals belonging to the echinoderm group, commonly called “sea stars” due to their distinctive star-shaped body.
- Feeding: They are primarily predators, preying on invertebrates like mussels and clams.
- Regeneration: Many species possess the ability to regenerate lost or damaged arms.
- Circulatory System: They lack blood; instead, seawater circulates through their water vascular system to transport nutrients and oxygen.
- Habitat – They are benthic in nature. They are found in all marine environments, from intertidal zones to depths of 6,000 m.
