Caridean shrimp are shrimp that belong to the infraorder Caridea. This group includes most of the “true shrimp” people eat and keep in aquariums.

They differ from other shrimp groups in a few anatomical ways:
- The second abdominal segment overlaps the first and third.
- They typically have well-developed claws on the first two pairs of legs.
- Many species have a distinctive curved body shape.
🌊 Where They Live
Caridean shrimp are found worldwide:
- Oceans (tropical to polar waters)
- Freshwater rivers and lakes
- Coral reefs
- Deep sea environments
🍽️ Common Edible Examples
Many popular seafood shrimp are carideans, including:
- Pandalus borealis (Northern shrimp)

🐠 Aquarium Favorites
Some small freshwater shrimp popular in aquariums are also carideans, such as:
- Neocaridina davidi (Cherry shrimp)
