When shark are recorded in Maine

Quick Answer: Yes, several shark species swim in Maine's coastal waters, including blue sharks, porbeagles, and makos. To start identifying them, focus on dorsal fin shape and body color. This guide covers the most common types you'll encounter from shore or on a boat.

1. What are the most common types of sharks in Maine?

The blue shark is the most frequently seen species offshore, often with a deep blue back and white belly. Porbeagle sharks resemble small great whites but have a secondary keel on the tail. Shortfin mako sharks are also present, known for their speed and pointed snout. For a full list of species, visit theshark overview page.

In Maine, sharks 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 brush, wetlands, timber, shoreline, or neighborhood cover.

2. How can you tell different shark species apart?

Start with the dorsal fin: blue sharks have a long, curved dorsal fin while porbeagles have a more upright fin with a white trailing edge. Body color helps too: blue sharks are vivid blue above, makos are metallic blue, and porbeagles are dark gray. Tail shape matters: makos have a lunate tail, blue sharks a more symmetrical one.

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 Maine. If movement slows, stay longer at one promising spot, listen for calls or watch for edge movement, and reset around weather, light, water, or feeding changes instead of jumping to a totally new area too early.

3. Where and when are you most likely to see each shark type?

Blue sharks are most common in summer and fall, often found in offshore waters near the Gulf of Maine. Porbeagles stick to deeper, cooler waters year-round but are sometimes caught by anglers. Shortfin makos appear in late summer, typically farther offshore. CheckMaine wildlife resourcesfor real-time sighting reports.

4. Are there any dangerous sharks in Maine waters?

Great white sharks are rare but have been recorded in Maine, especially near seal colonies. They are dark gray above with a white belly and a large, triangular dorsal fin. To separate them from similar species like porbeagles, note the great white's more useful body and distinct counter-shading. Always maintain a safe distance.
