What has eight arms, lives in the sea and shows up on menus all over the world? If you guessed octopus, then give yourself a pat on the back. Eight pats.

And if you've never tasted the delicacy, now may be the time to give it a chance. Here are four places to start.

CUZCO PERU, 23 Merrick Rd., Lynbrook

At this Peruvian restaurant, the grilled octopus is tender and savory. Served uncut, it's a great way to start your meal. ($9.75)

AEGEAN GRILL, 354 Larkfield Rd., East Northport

At this casual Greek spot, the octopus glistens with lemon and olive oil. It's served properly uncut, awaiting knife and fork. One bite tells the story: meaty, tender, every bit as good as it looks. ($12.95 appetizer; $21.95, entree)

PLANCHA TAPAS AND WINE BAR, 931 Franklin Ave., Garden City

This creative Spanish-style tapas bar offers octopus grilled to a state of tender succulence. These days, it's being plated with olive oil-poached potatoes, chorizo chips and charred ramp aioli. ($14)

YEVMA AUTHENTIC GREEK CUISINE, 2065 Hempstead Tpke., East Meadow

The food at this ambitious newcomer is overall very good, and you find that out at the moment you sink your teeth into the grilled octopus. Bathed in extra-virgin olive oil, it's exceptionally meaty and tender, subtly smoky.
