four starfish


Starfish, or sea stars, are a fascinating and diverse group of marine invertebrates found in a wide range of environments, including the coastal waters of Florida. Florida’s unique marine ecosystems, like the Gulf of Mexico, the Atlantic Ocean, and the vast network of reefs and mangroves, provide an ideal habitat for these creatures.

One of the most striking features of starfish is their star-shaped body, typically having five arms, although some species can have more. This distinctive shape is not just for show; it’s central to their mode of life. The underside of each arm contains hundreds of tiny tube feet, which are used for movement and feeding. These feet operate through a unique hydraulic system, allowing the starfish to move, cling to surfaces, and even open shells of prey like clams and oysters.

Starfish are known for their incredible regenerative abilities. They can regrow lost arms, and in some cases, an entire new starfish can grow from a single severed limb. This remarkable feature is not only interesting from a biological standpoint but also plays a role in their survival and propagation.

In Florida, starfish contribute significantly to the biodiversity and health of marine ecosystems. They often play the role of a keystone species, meaning their presence and activities have a disproportionately large impact on their environment. For instance, by preying on mussels and other bivalves, starfish help maintain the balance in these ecosystems, preventing any one species from dominating and altering the habitat.

We often come across starfish on our kayak tours of the Emerson Point Preserve. Book a kayak tour to see these fascinating creatures, along with manatees, dolphins, birds and other marine life. Book online at,
