Great question! Shrimp and clams are actually different types of shellfish. Shrimp are crustaceans, while clams are mollusks. Some people allergic to one group can tolerate the other — but it's not guaranteed.

Here's a quick breakdown:

- Crustaceans: Shrimp, crab, lobster, prawns
- Mollusks: Clams, oysters, scallops Show Full Answer

Great question! Shrimp and clams are actually different types of shellfish. Shrimp are crustaceans, while clams are mollusks. Some people allergic to one group can tolerate the other — but it's not guaranteed.

Here's a quick breakdown:

- Crustaceans: Shrimp, crab, lobster, prawns
- Mollusks: Clams, oysters, scallops, mussels, squid, octopus That said, it's never safe to test this on your own. If you've had a reaction to shrimp, you should get tested for other shellfish under medical supervision before trying clams. An allergist can do this safely in a clinical setting where help is available if needed.

Until you've been cleared by your allergist, it's best to avoid all shellfish to stay on the safe side.
