Starfish in New York: identification guide and where to start looking

1. What are the key identification features of starfish found in New York?

The most common starfish in New York is the Forbes's sea star (Asterias forbesi). Look for five arms that taper to a blunt point, a central disk, and a reddish-brown to purple color. The surface feels rough due to small spines arranged in rows running along each arm. The underside has hundreds of tiny tube feet that help it move and cling to rocks.

When you find a starfish, turn it over gently to check the tube feet pattern. On A. forbesi, these feet radiate from a central groove on each arm. The arms are relatively thick compared to the central disk, giving the starfish a stout appearance. Compare this to the thinner-armed northern starfish (Asterias rubens), which is far less common in New York and has a more delicate build.

In New York, starfish sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to rocks, pilings, sand, or mussel beds.

2. Where in New York are you most likely to spot starfish?

Your best odds are along the south shore of Long Island, especially at Montauk Point, Jones Beach, Rockaway Beach, and Fire Island inlets. Starfish cling to jetties, pilings, submerged rocks, and tide pools below the low tide line. Also check the rocky shores of the North Shore near Port Jefferson and Cold Spring Harbor. In New York Harbor itself, starfish inhabit the rocky margins near Staten Island and Brooklyn. Check thewildlife in New Yorkpage for more local spots.

The key is rocky substrate and wave action. Starfish avoid pure sand flats and prefer areas where mussels and hard clams accumulate, since these are their main prey. Piers and breakwaters are especially productive, as they create complex crevices and shadowed zones where starfish hide during the day.

3. When is the best time of year to see starfish in New York?

Late spring through early fall offers the best sightings, especially after a low tide that exposes intertidal zones. Early morning or late afternoon after an onshore wind increases your chances. Storms can wash starfish onto beaches, but those are often dead or injured.

Water temperature affects starfish activity. In summer, when water is warmest (60-70F), starfish are most active and easiest to spot on rocks. In winter, they move deeper to stay warm and are harder to find in the intertidal zone. Spring (April-June) is ideal because the water is warming and starfish return to shallow feeding areas. Fall (September-October) remains good before the temperature drop drives them deeper.

4. How can you tell a common starfish from a similar lookalike?

The most likely lookalike is the northern starfish (Asterias rubens), but it is much less common in New York. A key difference: A. forbesi has a more pronounced central disk and shorter, thicker arms relative to body size. A. rubens has thinner arms and a less distinct disk.

Brittle stars look similar at first glance but have long, thin arms that break off easily and move in a serpentine, walking motion. Their central disk is much smaller. Sea urchins are sometimes confused with starfish, but urchins are round with spines all over, not star-shaped.

If you find a starfish with six, seven, or more arms, it is likely a damaged common starfish that has regenerated lost arms (or lost an arm and grown a new one). Some starfish are naturally five-armed but vary in arm proportions. For more ID details, see thestarfish identification guide.

5. What should you do if you find a starfish on the beach?

If the starfish is alive (firm body, tube feet moving, slight resistance when you touch it), gently place it back in the water below the low tide line. Avoid pulling it off rocks, as that can damage its tube feet and suction ability. Dead starfish are brittle and often smell; you can take those home for closer inspection. Always check local regulations - some areas forbid collecting live sea creatures.

Never leave a live starfish on the beach or in the sun for more than a few minutes. They dry out and die quickly. If you accidentally damage a starfish's arm, returning it to the water does not harm it; starfish regenerate lost arms over several months.

6. What gear is helpful for starfish spotting in New York?

A pair of waterproof boots or waders lets you wade safely in cold water. A clear plastic bucket helps you examine specimens without handling them too much. A tide chart app on your phone is essential for timing low tides. You can also bring a field guide to seashore life or a smartphone camera for reference photos. For carrying your gear, a sturdywildlife tote bagis a practical choice.

8. Are starfish common in New York waters?

Yes, Asterias forbesi is common along the entire coast from Long Island to the Hudson River estuary. However, populations have declined in recent decades due to sea star wasting disease (a viral infection that causes arms to fall off), warming waters from climate change, and pollution in urban areas like New York Harbor.

You can still find them reliably on rocky shores and pilings, but numbers vary year to year. In years with heavy disease outbreaks, sightings may drop noticeably. Pristine rocky inlets often have healthier populations than urban harbors.

9. Can you find starfish in fresh water in New York?

No. All starfish are marine animals and cannot survive in fresh water. If you're inland, you'll only see them in aquariums, like at the New York Aquarium in Brooklyn or the Bronx Zoo's wildlife exhibits.

10. What happens when a starfish loses an arm?

Starfish are famous for their ability to regenerate lost arms. If a Forbes's sea star loses an arm to a predator, injury, or disease, it will slowly regrow a new one over the course of several months to a year, depending on the starfish's age and health. During regeneration, the new arm is typically smaller and paler than the original arms.

In rare cases, a starfish can survive with only two or three remaining arms and will eventually restore its full five-armed shape. Some individuals may have uneven arm lengths due to multiple rounds of loss and regrowth. This is normal and does not harm the starfish.

11. What color variations and sizes should you expect when identifying starfish in New York?

Forbes's sea star varies in color from brick red to deep purple to orange, and occasionally brown or tan. The color is not a reliable ID marker, as individuals of the same species in the same location can look quite different. Size is more consistent: most adults are 8 to 12 inches across, though specimens up to 14 inches are not uncommon. Juveniles may be only 1 to 2 inches across.

Older individuals often have bleached or faded coloring, especially if they have been exposed to strong sunlight or pollution. Newly molted starfish or those with fresh tube feet are brighter in color. Color alone should never be your only identification method; always check arm shape, disk size, and spine arrangement.

12. How do habitat conditions affect starfish identification in New York?

Starfish found in high-energy, wave-exposed zones tend to have shorter, thicker arms and a more strong central disk, which provides better grip strength. Starfish in sheltered bays and quieter water often have thinner arms and a more delicate build, resembling the northern starfish to the untrained eye.

Starfish living on mussel-covered rocks often have rougher spines because they are constantly moving and feeding, abrading their surfaces. Those in sandy or muddy areas may appear smoother and paler. Light exposure and food availability also influence coloring: starfish in bright, shallow intertidal zones may be darker, while those in deep water or shadowed crevices are often paler. When identifying starfish, always note the habitat and compare your specimen to photos from similar New York locations.
