Definition

Noun: - A subclass of crustaceans: "Subclass Ostracoda" is the scientific taxonomic classification for a group of small, bivalved crustaceans commonly known as seed shrimps or mussel shrimps.

Examples

• Scientific Classification:
  • The Subclass Ostracoda includes thousands of species found in both marine and freshwater environments.
  • Researchers are studying the fossil record of the Subclass Ostracoda to understand past climates.

Advanced Usage
