Types of Octopuses in Maryland

1. What Are the Most Common Octopus Species in Maryland?

The Atlantic octopus (Octopus vulgaris) is the primary species found off Maryland's coast, especially in deeper waters past the surf zone. You might also hear about the longarm octopus (Macrotritopus defilippi), but its sightings here are rare. Stick with the Atlantic species as your starting point.

In Maryland, octopuses 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...

2. How Can You Tell Apart the Different Octopus Types in Maryland?

Start with color and texture. The Atlantic octopus ranges from grayish brown to reddish, with smooth skin that can become bumpy when alarmed. Its arms are about three times its body length. In contrast, the longarm octopus has longer, slender arms and tends toward a pale brown. Size helps too: Atlantic octopuses reach about 3 feet across, while longarms stay smaller.

3. Where and When Are You Most Likely to See Each Type?

Your best odds for seeing an Atlantic octopus are in summer and early fall, when water warms. Head to theChesapeake Bay Bridge Tunnelarea or offshore wrecks like the *Relief* near Ocean City. Longarm octopuses are sometimes spotted in seagrass beds south of the state line, but consider them a bonus, not a target.

4. What Are the Key Identification Features of the Atlantic Octopus in Maryland?

Focus on the double row of suckers on each arm and the distinct, slightly flattened body. When disturbed, it can flash dark patches on its skin. A true ID comes from the gill count (seven to nine on each side) and the lack of a specific color pattern. Most sightings in Maryland are of young individuals, which are easier to mistake for other species.

5. Where to Look for Octopuses Along the Maryland Coast

Start with the cool, deep waters of theWilmington and Baltimore canyons(about 60 miles offshore). Closer in, try the rock piles near the Point Lookout jetty or the artificial reefs off Assateague. Night dives on these structures can reveal octopuses hunting small crabs. Always check local regulations before collecting or handling.

6. What Gear Helps With Octopus Spotting in Maryland?

A good dive light with red filter (so you don't spook them) and a small underwater camera help you record sightings. For land-based scouting, polarized sunglasses cut the glare on shallow reefs. Check ourwildlife tote bagsto carry your field guides and snacks during a day out.
