Octopus vs Squid vs Cuttlefish: What's the Difference?

Octopus vs Squid vs Cuttlefish: What's the Difference?
Quick answer: All three are cephalopods. Octopus has 8 arms, no tentacles, no internal shell, and is the meatiest; it needs long, slow cooking. Squid (calamari) has 8 arms + 2 tentacles, a torpedo body, and a clear plastic-like quill; it is mild and tender if cooked fast or slow. Cuttlefish has 8 arms + 2 tentacles, a wide flat body, and a hard cuttlebone; it is the richest and most tender of the three.
Key facts:
- Octopus: 8 arms, no tentacles, no internal shell, meatiest, needs long slow cooking
- Squid (calamari): 8 arms + 2 tentacles, torpedo body with tail fins, clear quill, mild and tender
- Cuttlefish: 8 arms + 2 tentacles, wide flat body, hard cuttlebone, richest and most tender
- Calamari is squid, never octopus
- Most tender: cuttlefish; meatiest: octopus; best for rings: squid
- Squid and cuttlefish follow the fast-or-slow rule; octopus needs the slow route or tenderising
- All three are local to Gold Coast / Queensland waters
How to Tell Them Apart
| Squid (calamari) | Octopus | Cuttlefish | |
|---|---|---|---|
| Arms / tentacles | 8 arms + 2 long tentacles | 8 arms, no tentacles | 8 arms + 2 tentacles |
| Body shape | Torpedo, fins at tail | Round, soft head | Wide, flat oval |
| Internal shell | Clear plastic-like quill | None | Hard cuttlebone |
| Texture | Mild, tender when quick or slow | Meaty, firm | Richest, most tender |
| Best for | Rings, frying, quick grill | Grilling after slow cook | Scored grill, stews, ink dishes |
| Tenderness | Fast or slow only | Needs long cooking | Most forgiving |
Squid / Calamari: The Mild All-Rounder
Squid has a torpedo-shaped body with two fins at the tail, eight arms, and two longer tentacles. Inside is the clear, plastic-like quill. In Australia, squid and calamari mean much the same thing (calamari often being the more tender species).
- Taste: mild, clean, slightly sweet
- Best for: calamari rings, salt & pepper squid, quick grilling, stir-fries
- The catch: it goes rubbery if cooked for the wrong length of time

Octopus: The Meaty One
Octopus has eight arms and no tentacles, a soft round head, and no internal shell at all. It's the meatiest of the three, with a savoury, almost "meat-like" character once cooked.
- Taste: rich, savoury, meaty
- Best for: grilling and charring, after tenderising
- The catch: it's tough raw and needs a long, gentle cook (45–60 min simmer) before it turns tender
Baby octopus is the easy exception. Naturally tender, it just needs quick, hot cooking.

Cuttlefish: The Rich, Tender Secret
Cuttlefish looks like a wider, flatter squid, with eight arms, two tentacles, and a hard internal cuttlebone (the white oval you've seen in budgie cages). Its meat is thicker, richer, and more tender than squid, and it carries lots of ink.
- Taste: rich, slightly sweet, meatier bite than squid
- Best for: scoring and grilling, seafood stews, squid-ink pasta and rice
- The bonus: it's the most forgiving of the three to cook
Clean it just like squid (remove the cuttlebone, guts, beak, and skin), then cook it fast-and-hot or slow-and-low.
Which Should You Buy?
| You want to make… | Best choice |
|---|---|
| Calamari rings (fried) | Squid tubes |
| Salt & pepper "calamari" | Squid |
| Charred grilled tentacles | Octopus (tenderised) or cuttlefish |
| A rich seafood stew | Cuttlefish |
| Squid-ink pasta or risotto | Cuttlefish (most ink) or squid |
| Quick weeknight grill | Baby octopus or cuttlefish strips |
| Most tender, beginner-friendly | Cuttlefish or baby octopus |
They Cook by the Same Rule (Mostly)
Squid and cuttlefish both follow the fast-or-slow rule: sear in 1–2 minutes or braise for 30–45 minutes, never in between. Octopus is the outlier: it wants the slow route (or a tenderising step) almost every time, then a quick char to finish.
