Types of Octopus in Texas
Texas Gulf Coast waters host two main octopus species: the Atlantic common octopus (Octopus vulgaris) and the Atlantic longarm octopus (Macrotritopus defilippi). Both are most often encountered near jetties, piers, and rocky reefs. Start your identification by looking at arm length relative to body size.

What are the most common octopus species in Texas?
Along the Texas coast, the two octopus species you are most likely to see are the **Atlantic common octopus** (_Octopus vulgaris_) and the **Atlantic longarm octopus** (_Macrotritopus defilippi_). A third species, the Caribbean reef octopus (_Octopus briareus_), appears occasionally around offshore reefs. For a broader look at Texas wildlife, check out the/wildlife/texasguide.
How can you identify the Atlantic common octopus?
The Atlantic common octopus has a round, sac-like body and arms that are about 3–5 times the length of its mantle. Its skin is usually brownish or gray with rough texture and small papillae. Look for a distinct pair of white spots on the top of the head, which are often visible in clear water.
How can you identify the Atlantic longarm octopus?
The Atlantic longarm octopus has very long, slender arms that can reach 8–10 times the length of its mantle. Its body is more elongated than the common octopus, and its skin is smoother. It is often pale gray or tan with faint mottling. This species is frequently seen in sandy or muddy habitats near seagrass beds.
Where are octopuses most likely to be found in Texas?
Octopuses in Texas are most often encountered around **rocky jetties**, **pier pilings**, and **artificial reefs** from Galveston to Port Isabel. The Atlantic common octopus prefers hard-bottom structures, while the longarm octopus is more common on soft bottoms. For specific spots, refer to the/wildlife/texas/octopus/typespage.

When is the best time to spot octopuses in Texas?
Octopuses are active year-round in Texas, but the best odds are from **late spring through early fall** when water temperatures are above 70°F. Nighttime low tides often drive them into shallower water, making them easier to find with a flashlight. Always check local tide charts before heading out.
What other octopus species are occasionally seen in Texas?
Rare visitors include the **Caribbean reef octopus** (_Octopus briareus_) on deep reefs and the **California two-spot octopus** (_Octopus bimaculoides_) reported from shipwrecks. These are not common enough to rely on, but experienced divers may spot them. For more about octopus biology, visit the/animals/octopushub.
