Common starfish

The common starfish is a five-armed sea star found along the northeast Atlantic coast. It thrives on rocky seabeds, where it snacks on shellfish and other small ocean-floor dwellers. You’ll spot it in shades of orange, brown, or sometimes pale violet if it lives in deeper waters.

• Grows between 10–30 cm across, with some even bigger.
• Feeds mainly on mollusks and bottom-dwelling invertebrates.
• Deeper-water starfish are paler than their shallow-water cousins.
