# decapod

noun (a decapod, decapods)

«decapod» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

(science) A decapod is a crustacean with ten legs, such as a crab, lobster, shrimp, prawn or crayfish. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/decapod/#m1)

### In the lessons

In science lessons about animal groups: decapods belong to the crustaceans, which belong to the arthropods (animals with jointed legs and a hard outer skeleton). Two of the ten legs are often big claws (pincers).

### Examples

### Note

Countable. «Deca» means ten; «pod» means foot. Note: in older books, squids were also called decapods (ten arms), so the word has two scientific uses.
