Notes
In April 2000, a massive bloom of C. mastigophora stretched about 1200 km along Western Australia's coastline from Derby to Rottnest Island. However, scientific data was not collected from this event, and a collection of anecdotal observations remains unpublished to this day.
Since that time, the species has been observed several more times, but not in the same numbers as in 2000. No explanation for its occurrence in Australian waters has been offered.
