Two different animals are sold into world markets under the single word langostino. If your specification says only "langostino, IQF, shell-on", you have not actually specified the product you will receive. This guide sets out the difference between red and yellow langostino and the four spec lines that remove the ambiguity.
The two species
Red langostino (Pleuroncodes monodon, squat lobster, locally langostino colorado) and yellow langostino (Cervimunida johni, langostino amarillo) are both squat lobsters — galatheid crustaceans, closer to hermit crabs than to true lobsters or to penaeid shrimp. Both are landed off the Chilean coast in the Humboldt Current system, and both are inside the scope of the Chilean squat lobster and nylon shrimp trawl fishery that this company's MSC fishery certificate covers.
They are landed by the same fleet, often on adjacent grounds, and processed on the same IQF lines. What differs is the animal.
| Attribute | Red langostino | Yellow langostino |
|---|---|---|
| Scientific name | Pleuroncodes monodon | Cervimunida johni |
| Raw shell colour | Deep red-orange | Pale orange to yellow |
| Typical landed size | Smaller, more uniform | Generally larger-bodied |
| Tail meat | Smaller pieces, sweeter, softer | Larger pieces, firmer bite |
| Usual commercial pull | Volume programmes, blends, value formats | Presentation formats, larger visible pieces |
Why the distinction shows up in your costing
Squat lobster is a low-yield animal by nature. The usable product is the tail; the cephalothorax, shell and legs are not sold as food. Peeled tail-meat yield from whole landed weight is in the low tens of percent for galatheids — an order of magnitude different from a fish fillet, and the single biggest driver of the delivered price of peeled langostino.
Because yellow langostino runs to a larger body, a kilo of peeled yellow tail meat generally represents fewer individual animals than a kilo of peeled red. That matters if your end product is judged on visible piece size — a paella topping, a seafood salad, a retail cocktail pack — and matters much less if the meat is going into a bisque, a filling or a blended value-added item.
Cooked vs raw, shell-on vs peeled
Squat lobster is very commonly sold cooked. The animal's own enzymes work fast, and cooking early in the process stabilises texture and locks the shell colour. The formats published for our langostino line are cooked shell-on, raw shell-on and peeled tail meat, all individually quick frozen.
- Cooked shell-on — the strongest visual presentation. Colour is fixed and the shell protects the meat through freezing and distribution.
- Raw shell-on — for buyers who want to control the cook themselves, typically because the meat goes into a sauce or a further-processed line.
- Peeled tail meat — highest labour input and lowest yield, therefore the highest per-kilo cost, but zero waste and no handling on the customer's line.
The shell-on versus peeled decision is a landed-cost calculation rather than a preference; we set out the arithmetic in shell-on or peeled.
The four lines that make a langostino spec unambiguous
- Species, by scientific name. Pleuroncodes monodon, Cervimunida johni, or an accepted mix — state which.
- Cook state. Raw or cooked, and if cooked, whether colour is assessed on the shell or on the meat.
- Format and presentation. Shell-on or peeled; whole tail or broken meat tolerance as a percentage.
- Freezing and glaze. IQF, glaze percentage, and whether the declared weight is net of glaze.
Add the certification scheme reference if your retail customer requires chain of custody on the label — that is a separate certificate from the fishery one, and the distinction is explained in reading an MSC certificate.
Labelling: what you may and may not call it
Naming rules differ by destination and this is where langostino programmes most often run into trouble. Squat lobster is not a true lobster and not a penaeid shrimp, and several markets restrict which market names may appear on a consumer pack. Some jurisdictions require the scientific name or a specific accepted common name on the label; the United States has had specific enforcement history around lobster-style naming for Pleuroncodes. Confirm the accepted market name with your own regulatory adviser for each destination before artwork is signed off — the correct name belongs in the specification, not discovered at the port.
Seasonality and supply planning
Squat lobster fisheries in Chile operate under documented catch limits with managed seasons, and landings vary through the year and between grounds. For an annual programme this means two things in practice: agree size and species tolerances that reflect a real season rather than a single sample, and set your call-off schedule against production windows rather than assuming uniform monthly availability. Our export team confirms current availability by species and format on request.

Frequently asked
Is langostino a lobster, a prawn or a shrimp?
Neither a true lobster nor a penaeid shrimp. Red and yellow langostino are squat lobsters — galatheid crustaceans. The eating quality sits between the two, which is why market naming rules vary by country and should be confirmed for each destination.
Can red and yellow langostino be mixed in one lot?
They can, and mixed lots are traded, but the mix has to be stated in the specification with a tolerance. An unstated mix is the most frequent source of piece-size complaints.
Which species gives larger peeled pieces?
Yellow langostino (Cervimunida johni) is generally the larger-bodied of the two, so a kilo of peeled meat tends to contain fewer, larger pieces.
Why is peeled langostino so much more expensive than shell-on?
Tail-meat yield from whole landed weight is low for squat lobsters and peeling is labour-intensive. You are paying for both the discarded weight and the labour, which is why the shell-on versus peeled decision should be made on cost per usable kilo.
