Box jellyfish - Wikipedia
Cubozoans usually have an annual life cycle. Box jellyfish reach sexual maturity when their bell diameter reaches 5 millimeters. [34] Chirodropida reproduces by external fertilization. Carybdeida instead reproduces by internal fertilization and is ovoviviparous; sperm is transferred by spermatozeugmata, a type of spermatophore. [35]
