Salad: Good to eat? Maybe for some, but not for us here at Critters Up Close! Little Salad is referred to as an echinoderm, closely related to the sea star and sea urchin. Found all around the world, they can live from shallow shores to the bottom of the deep blue. They like to feed on tiny particles consisting of waste, small aquatic animals and algae. Some, when threatened can release a sticky white substance or push their insides, outside. How’s that for a cool defense mechanism?
