Types of Starfish in New Jersey
Starfish do show up in New Jersey, and the best first step is matching habitat, timing, and recent local conditions. Start with the state wildlife hub, compare likely cover and movement windows, use the animal facts page for field marks, and plan one realistic route before heading out.

1. What are the most common types of starfish in New Jersey?
Forbes' sea star (*Asterias forbesi*) and the northern sea star (*Asterias rubens*) are the two you are most likely to find. Forbes' sea star has a tan to brown color and a slightly swollen tip on each arm. The northern sea star is more variable in color, often reddish or purple, and prefers cooler water.
In New Jersey, 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...
2. How can you tell apart the main starfish species?
Check the arm tips: Forbes' sea star has a distinct white or pale spot at the base of each tip, while the northern sea star does not. Also look at size; Forbes' sea star rarely exceeds 10 inches across, whereas northern sea stars can grow a bit larger. Count the arms? Most have five, but occasional four or six arms show up.
Most misses happen when people arrive at the wrong hour or expect nonstop activity. Build around where in the state people usually notice them first, keep one backup area in mind, and use theanimal facts pageplustour planning ideasto compare what a realistic outing looks like in New Jersey.

3. Where and when should you look for each type?
Forbes' sea star is common on jetties and rocky shores from spring through fall. Northern sea stars show up more in winter and early spring, often in deeper bays. Check the back bays of Barnegat Bay or the rocks near Sandy Hook. Low tide is your best time.
4. What about less common starfish in New Jersey?
Occasionally you might spot the blood star (*Henricia sanguinolenta*) or the fragile star (*Ophiopholis aculeata*), but these are rare. Blood stars are bright red and live in deeper offshore waters. Fragile stars are brittle and usually lost in seaweed. Stick to the common ones first.

5. How do tides affect starfish sightings?
Starfish are easiest to find at low tide when they are stranded in tide pools or clinging to exposed rocks. A minus tide (below average low) opens up more habitat. Check a tide chart for New Jersey beaches and plan your trip around a negative low tide.
6. What gear helps with identifying starfish?
A small waterproof field guide or a phone with a marine ID app works. For handling, wet your hands first to avoid harming the starfish. If you want to keep track of your sightings, a lightweight tote bag can hold a guide and a camera.Check out our wildlife tote bags.
