The best foods to include in a sea star's diet are clams, oysters, mussels, snails, shrimp, squid, and marine worms. Having mastered horizontal balance first is helpful to learn this technique.

They lose their capability to maintain the water pressure normal, and instead of buoyancy, they start to float on the water surface. Its because taking starfish out of the water could be life-threatening to them. However, lets not lose sight of the sentiment of this article which is clearly to pass on advice to people who may not realise pulling marine creatures out of the water *can* cause harm. In fact, many live in intertidal zones where they live more than half their life exposed to air. When fish die, they usually float on the water surface due to air in the swim bladder. Because how can you explain starfishes that walk through the shores during tidal changes or stick through rocks or docks if you are so fixed on the broad fact that they are marine animals and could not stand being lifted out of the water. Papulae are really very soft skin gills of the starfish. Floating upside down, sitting at the top or bottom of the tank, and erratic spiral swimming are also signs your fish is ill and possibly dying.
