Last updated: April 8, 2020 at 0:13 am

Giant kelp (Macrocystis pyrifera)61 cm (24 in.) per day, northeastern Pacific Ocean. Although giant kelp plants are perennial, each frond survives for about 6-9 months. Macrocystis pyrifera is also the world’s longest seaweed.

Bull kelp (Nereocystis leutkeana) — 15 cm (6 in.) per day, northeastern Pacific Ocean.

Caulerpa taxifolia, a.k.a. Killer weed — 8 cm (3 in.) per day, Côte d’Azur (France). Due to its fast-growing nature, C. taxifolia is very popular with aquarists. Accidental discharges of C. taxifolia in the Mediterranean Sea have led to the infestation of tens of thousands of acres. C. taxifolia was recently found in coastal areas in southern California.
