100 Examples of sentences containing the common noun "planula"

Definition

A planula is a free-swimming, ciliated larval stage in the life cycle of certain cnidarians, such as jellyfish and corals. It typically develops from the fertilized egg and eventually settles to form a polyp.

Synonyms

• Larva
• Cnidarian larva

Antonyms

• Adult
• Mature organism
