Sea-stars, commonly known as starfish, are marine invertebrates belonging to the class Asteroidea. They are recognized for their distinctive five-arm (or more) radial symmetry and vibrant coloration. Starfish are primarily found on the ocean floor across various marine environments, from tidal pools to deep sea habitats. They play a crucial role in their ecosystems as predators and scavengers, feeding mainly on mollusks like clams and mussels.

- Feeding through eversible stomachs that can extend outside their body to consume prey
- Colorful and varied appearances depending on species and habitat
Pros
- Unique and fascinating creatures with interesting behaviors
- Important for maintaining ecological balance in marine environments
