Spiny lobster vs Maine lobster: the Florida spiny lobster (Panulirus argus) has no claws, long spiny antennae and is sold almost entirely as tails; the Maine, or American, lobster (Homarus americanus) has two big claws and is sold live and whole. Maine lobster is sweeter and more tender and gives you claw meat; spiny lobster tail is firmer, a little less sweet, and is the better choice for grilling.
Order Maine lobster for a whole-lobster dinner with butter and crackers. Order spiny lobster when the menu says “lobster tail” or “Florida lobster” and you want a tail to grill or broil.

Do spiny lobsters have claws?
No. The defining difference is right there on the plate. NOAA says the Caribbean spiny lobster lacks the American lobster’s large front claws and instead carries forward-pointing spines over its body and “long, horn-like antennae over their eyes that they wave to scare off predators.” The American lobster is built around its claws. NOAA describes a crusher claw for pulverizing shells and a ripper claw with a finer edge, “like a steak knife,” for tearing. That is why a Maine lobster dinner comes with crackers and picks, and a Florida lobster dinner comes as a tail.
Where do spiny lobster and Maine lobster come from?
Spiny lobster is a warm-water animal. NOAA puts its range along the continental shelf from North Carolina to Texas, in Bermuda, throughout the Caribbean and south to Brazil, in water to about 295 feet. The US fishery runs out of Florida, mainly the Keys, plus Puerto Rico and the US Virgin Islands; commercial crews use traps, diving and nighttime bully-netting. Maine lobster is a cold-water animal. NOAA gives its range as the northwest Atlantic from Labrador to Cape Hatteras, most abundant from Maine through New Jersey, caught in baited wire traps in 15 to 1,000 feet of water.
Does spiny lobster taste different from Maine lobster?
Yes, but less than the price gap suggests. NOAA uses the same two words for both, “mild and sweet,” and the same word for texture, “firm.” The difference is in degree. Maine lobster is the sweeter, more succulent of the two, and its claw and knuckle meat is softer and more delicate than anything a spiny lobster offers; NOAA notes the American lobster’s tail meat is firmer than its claw meat. Spiny lobster tail is firmer and a touch less sweet, with a cleaner, more shrimp-like bite.
NOAA adds a detail worth remembering when you buy frozen tails: cold-water spiny tails tend to be more tender than warm-water tails. Florida and Caribbean tails are warm-water. Our Florida spiny lobster guide and what lobster tastes like go deeper on flavor.
Which is healthier?
Both are lean, high-protein shellfish on the FDA/EPA “Best Choices” list for mercury, which names “Lobster, American and spiny” together. USDA FoodData Central puts cooked spiny lobster at 143 calories, 26.4 g protein and 1.9 g fat per 100 g, with 7.3 mg zinc and about 0.5 g of omega-3 EPA+DHA. Cooked northern lobster is 89 calories, 19.0 g protein and 0.9 g fat, with more cholesterol, 146 mg vs 90 mg, and more sodium. Spiny lobster is the denser, more nutrient-rich meat; Maine lobster is the lighter one.

Is spiny lobster cheaper than Maine lobster?
It depends on the form. A frozen spiny lobster tail is usually cheaper per serving than a live Maine lobster of comparable yield, and far cheaper than picked claw-and-knuckle meat, which is the most expensive lobster product you can buy. Priced per pound of edible meat the gap narrows, because a live lobster is mostly shell, and spiny tails climb in the Florida off-season from April through early August when fresh local tails are off the market. Prices move with the season and the catch, so check the day’s menu or counter price.
Sustainability cuts the other way from what most people expect. In its February 2024 recommendation list, Seafood Watch rates the Florida spiny lobster trap fishery a yellow Good Alternative, while US and Canadian American lobster trap fisheries are rated red, Avoid, over entanglement risk to North Atlantic right whales.
When is Florida lobster season?
Florida sets two recreational seasons for spiny lobster, and the rules are strict enough that it pays to read them before you go.
- Sport season (mini-season): two days, the last consecutive Wednesday and Thursday of July. Florida Administrative Code 68B-24.005 fixes it as “the last Wednesday and successive Thursday of July each year,” and Biscayne National Park notes it runs from 12:00 a.m. Wednesday to 11:59 p.m. Thursday. Night diving is prohibited in Monroe County during the sport season.
- Regular season: August 6 through March 31, in state rule and in the park’s rules alike. NOAA confirms the federal waters off Florida and the Gulf states are closed from April 1 through August 5.
- Limits: six lobsters per person per day in the Florida Keys (Monroe County) and Biscayne National Park; the statewide limit outside those areas is higher. The carapace must measure more than 3 inches, measured in the water, and every diver must carry a gauge. Egg-bearing females go back unharmed, lobsters must stay whole until you reach shore, and spears and hooks are banned.
- Paperwork: UF/IFAS Extension’s summary is blunt: you need a Florida recreational saltwater fishing license and a spiny lobster permit unless exempt. Certain park and sanctuary waters are closed to lobstering year-round.
If you only want to eat them, the practical takeaway is that fresh Florida tails show up on menus from August, with NOAA noting fishing drops sharply after New Year’s, and the rest of the year you are eating frozen.

Which should you order?
- Whole-lobster dinner, crackers, drawn butter: Maine lobster. You want the claws.
- Lobster roll: Maine. Rolls are built on claw and knuckle meat.
- Grilled or broiled tail: spiny lobster. The firm tail takes direct heat and smoke.
- Surf and turf: either, but a spiny tail is the usual, and the better value.
- Florida restaurant in August or September: fresh local spiny tail, simply broiled with butter and lime.
Fish On Fire’s menu is Gulf fish, shrimp and gator rather than lobster, but if you are comparing shellfish for a Florida seafood night, our crab vs lobster and crawfish vs lobster guides cover the other two contenders.
Bottom line
Maine lobster has claws, is sold live and is the sweeter, more tender eating; Florida spiny lobster has no claws, is sold as tails and is firmer and built for the grill. Buy Maine for the whole-lobster experience and spiny for tails, and remember that the fresh Florida season runs August 6 to March 31.
