Octopuses in Louisiana: identification guide and where to start looking

1. What are the key field marks to identify an octopus in Louisiana?

Look for a round, bulbous head with two large eyes that have rectangular pupils. The eight arms are lined with two rows of suckers and are much longer than the body. The skin can rapidly change color and texture to match the surroundings. A pair of white spots (ocelli) on the head is a classic sign of the Atlantic octopus.

2. Where should you start looking for octopuses in Louisiana?

Focus on the coasts: Grand Isle, the Chandeleur Islands, and the rock jetties at the mouth of the Mississippi River. Octopuses hide in crevices, under rocks, and inside discarded shells or bottles. Artificial reefs and pier pilings also hold them. In Lake Pontchartrain, check the concrete jetties near the Causeway.

3. What is the best season and time of day for octopus sightings?

Summer months from June through September offer the warm water octopuses prefer. Nighttime low tides are ideal because octopuses leave their dens to hunt. Use a flashlight with a red filter to avoid spooking them. Early morning or late evening in the summer also works if you are looking in shaded crevices.

4. How can you separate an octopus from common lookalikes?

Squid have a torpedo-shaped body with fins and a rigid internal pen. Cuttlefish have a broad, wavy fin along the body and W-shaped pupils. Octopuses have a rounded head, no fins, and round pupils. If the animal is in a den and reaches out an arm, it is almost certainly an octopus. Check our /wildlife/louisiana page for more identifiers.

5. What octopus behaviors help with identification?

Watch for color changes: a resting octopus is mottled brown, but when alarmed it turns white or red. If threatened, it may shoot a jet of ink or squeeze into a tiny crack. The way it moves also helps: it crawls using the front arms or jets backward by expelling water through its siphon.

6. What local regulations apply to octopus observation?

In Louisiana, you do not need a license to observe octopuses, but if you plan to handle or collect them you need a valid recreational fishing license. It is illegal to use traps in certain artificial reef zones. Always check current state rules on the Louisiana Department of Wildlife and Fisheries site.

7. What should you do if you spot an octopus?

Stay still and observe from a distance. Bright lights and sudden movements cause them to hide. Take a photo if you can; it helps confirm the species. Report unusual sightings to the Louisiana Coastal Marine Program. Consider wearing a shirt from our /tote-bags page that celebrates Louisiana marine life.
