Common Octopus

A variable-colored octopus with a textured body and stout arms bearing two rows of suckers. These traits alone do not distinguish every similar octopus species.

Usually a few pounds when caught. They grow fast and most live only 1–2 years, so size varies a lot with age.

SeaLifeBase lists a maximum of about 10 kg (22 lb) and up to 1.8 m (6 ft) long with arms spread.

Found in Puerto Rico and in warm and temperate seas worldwide. Scientists now split the Caribbean “common octopus” into close relatives (such as Octopus insularis) that look almost the same. Search rocky shorelines, reef edges and rubble flats.

Rocky coasts and shallow subtidal habitats.

Mostly from the tide line down to about 100 m (330 ft); recorded as deep as about 350 m.

Present year-round. Check for local closures or protected areas before collecting.

Most active at dusk, at night and early morning. In daytime they hide in dens.

Calm, clear water around low tide makes dens easier to spot in the shallows. Never risk surf or exposed reef.

Calm seas and good visibility. Avoid rough water — you need to see the bottom and keep your footing.

Crab is the classic octopus attractant; they also go for clams and fish scraps. Octopus are not usually taken on regular hook-and-line.

Weighted crab-imitation octopus jigs are used in some places. Check local rules first.

Mask and snorkel, a dive light, gloves and a mesh bag or lidded bucket. For jigging: a short, sturdy rod.

Octopus jigs use a ring of small hooks; no standard hook size applies.

If jigging from a boat or pier, 30–50 lb line helps pull the jig free of rocks.

Not usually needed.

Look for den signs: a pile of empty crab and clam shells outside a hole. Never use bleach or chemicals to drive an octopus out — it kills the reef and is illegal.

Excellent eating — the star of Puerto Rico’s ensalada de pulpo (octopus salad). Keep it on ice; freshness matters.

Remove the beak, eyes and innards (turn the head inside out). Rub off the slime with coarse salt. Freezing overnight or simmering slowly makes the meat tender.

Boil it slowly until tender, then cut into rounds for ensalada de pulpo: olive oil, lime, onion, sweet peppers, olives and a little garlic. Also great grilled after boiling, or in a garlic-and-tomato stew.

An octopus can bite with its sharp beak, and its saliva is mildly venomous. Hold it by the head, wear gloves and keep it away from your face.

No octopus-specific size, bag or season limits are listed here. Using bleach or other chemicals is illegal in Puerto Rico. Check current DRNA rules and stay out of natural reserves and no-take zones.

Short-lived and fast-growing, but heavily fished in places. Leave females guarding eggs in their den alone.
