Types of Sharks in Connecticut: identification guide and where to start looking

1. What are the most common types of sharks found in Connecticut waters?

Connecticut's waters, primarily Long Island Sound, host a handful of shark species. The smooth dogfish (Mustelus canis) is the most frequently encountered. It has a rounded dorsal fin and no spines. Spiny dogfish (Squalus acanthias) are also common; they have a sharp spine in front of each dorsal fin. Sand tiger sharks (Carcharias taurus) appear occasionally, recognized by their protruding, ragged teeth and a stout body. Other less frequent visitors include dusky sharks and thresher sharks.

2. Where in Connecticut can you typically spot sharks?

The best odds for shark sightings are along the shoreline of Long Island Sound, particularly near the mouths of rivers like the Thames, Housatonic, and Connecticut, where baitfish gather. Rocky reefs and shoals around Fishers Island and the Race also concentrate prey. Anglers often report dogfish in harbors and bays. Shark sightings from the beach are rare, but possible at state parks like Hammonasset Beach or Rocky Neck.

3. What is the best time of year for shark sightings in Connecticut?

Sharks are most often noticed from June through October, when water temperatures exceed 60°F. The peak window is late July to early September, when smooth dogfish and spiny dogfish are most active inshore. Sand tiger sharks tend to appear in the sound during summer months. Cooler water in spring or fall drives most sharks offshore, so target the warmest months for confident sightings.

4. How can you identify a smooth dogfish vs. a spiny dogfish?

Look at the dorsal fins. Smooth dogfish have two similarly sized, rounded dorsal fins with no spines. Their body is grayish with white spots in some individuals. Spiny dogfish have a prominent white spine at the front of each dorsal fin, a smaller second dorsal fin, and a slender, darker body without spots. Smooth dogfish grow larger (up to 5 feet) than spiny dogfish (max 4 feet), but average sizes overlap.

5. Are there any dangerous sharks in Connecticut?

No confirmed unprovoked shark attacks have occurred in Connecticut. Sand tiger sharks look intimidating due to their visible teeth but are not aggressive toward humans. Spiny dogfish and smooth dogfish are harmless. Bull sharks and great whites are exceptionally rare in Long Island Sound; reports are unverified. Swimmers face minimal risk, but avoid fishing areas where sharks are attracted to bait.

6. What should you do if you see a shark while swimming?

Stay calm and maintain eye contact. Slowly swim back to shore without splashing. Do not turn your back or flail. Most sharks in Connecticut are small and uninterested in humans. If you are fishing and catch a shark, handle it carefully with wet hands and release it quickly. Bull sharks have low chances of appearing, but avoid swimming near dawn or dusk when sharks feed.
