Knobby Star White 4"-5" (2pcs) special and the exterior is sculptedThe Knobby Star is sometimes called the jeweled star because of the blue and white knobs all over its body. Diet: The mouth of the Knobby Star is located on its underside, and when eating, the sea star actually extends its stomach out through its mouth and digests its prey externally. The Starfish you receive may not look exactly like the image. No two are alike.
