Deep Dive - How Do Starfish Move

Starfish, or Sea stars are awesome - and often overlooked!
Starfish are marine invertebrates. They typically have a central disc and five arms hence the name, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. They are opportunistic feeders and are mostly predators on benthic invertebrates.
The underside of the starfish is covered with hundreds of tube feet, which it uses for walking around, for attaching tightly to rocks, and for holding on to prey. To move, each tube foot swings like a leg, lifting up and swinging forward, then planting itself on the ground and pushing back. At the tip of each tube foot (in most species) is a suction cup. These aren't used when walking on level ground, but can be used when walking up sheer surfaces.
With so many little legs, starfish can reach enormous speeds - Some are clocked going over 30 centimetres per minute, and some species, like the sunflower star go even faster!
