What does strobilation mean?
Strobilation is the reproductive process in which certain jellyfish transform a polyp-like form into a strobila, an orderly stack of disc-shaped young medusae. Each disc eventually separates from the stack and continues developing as an independent jellyfish. The process can therefore produce numerous offspring from a single organism and is an important stage in the life cycle of scyphozoan cnidarians. The term is chiefly used by zoologists, aquarium researchers, and marine biologists. Although strobilation is sometimes described informally as the jellyfish dividing itself, its precise meaning is the specific formation and segmental release of the strobila rather than ordinary cell division or reproduction in general.
nounThe formation of a strobila in certain cnidarians, especially jellyfish, in which a stalked body divides into a stack of disc-shaped segments that mature and separate as new medusae. The process enables one organism to produce many offspring through repeated budding and division.
- The biological process by which a strobila forms and divides into separate young medusae, especially in scyphozoan cnidarians.
"Researchers observed strobilation in the sea nettle, identifying several stacked young medusae ready to be released."
"The polyp entered the season's strobilation, producing a column of developing jellyfish."
"Temperature and food availability can influence when strobilation occurs in a colony."
The plural is rare; the process is often discussed in the singular or as an uncountable occurrence.
"Seasonal strobilations were observed across several jellyfish colonies."
During strobilation, a jellyfish becomes a kind of living assembly line, releasing a stack of young medusae that can develop into copies of its former self.

Etymology of strobilation
The word derives through New Latin from the Greek strobilos, meaning “wreath,” an appropriate image for a series of disc-like bodies arranged in a stacked ring. In biological usage, strobila refers to the segmented stage formed during strobilation. Related English words such as strobilus and strobile use the same Greek root, originally in botanical senses involving cone-like structures.
How strobilation is actually used
This is a specialized biological term, normally used in zoology and discussions of cnidarian life cycles. It is not a general synonym for flashing, strobing, or rapid repetition.
