Nothing wrong with starfishes keeping the price there for serious buyers. Many funny people around. Some will ask for cheap price, buy the animal, and sell it again.
Don't put it with the zoo. Animals that are passed on to them never come to a good end.
[There are 16 different species of Hedgehogs. All of them are listed by the International Union for Conservation of Nature, (IUCN) the Red List, with a status of "least concern". Some have different population trends, but most of these are generally "decreasing", or "unknown". There are no species of Hedgehogs listed with a status of endangered on the IUCN Red List now, or listed by the U.S. Fish and Wildlife Endangered Species List either.]
