Hello, I'm an expert in marine biology. When it comes to starfish, also known as sea stars, it's important to understand that they don't have a mouth or teeth in the way that most animals do. Instead, they have a unique feeding mechanism.

Starfish have a central disc with five or more arms, depending on the species. On the underside of each arm, there is a groove known as the stomach, which can actually push out through the mouth, which is located on the underside of the central disc. When a starfish catches its prey, it wraps its arms around the prey and uses tiny, non-retractable, and blunt-tipped pedal digestive appendages called tube feet to grip and manipulate the prey. The stomach may then extrude a digestive enzyme to start the process of digestion externally.

While the starfish doesn't "bite" in the traditional sense, it can exert a strong grip with its tube feet, which might feel like a bite to the touch. However, this grip is not typically used to harm humans or cause pain but is part of its feeding process.

So, to answer your question: Starfish do not bite in the way that animals with teeth do, but they can exert a strong grip with their tube feet during feeding.

A starfish is marine creature that normally inhabits the deep ocean floors. Some species are venomous to human beings. Starfish do not attack humans, but can inflict painful stings with the release of venom, when they are accidently stepped upon or handled.read more >>
