Sea cactus (Caulerpa cactoides) is one of numerous species of the seaweed genus Caulerpa, which is found on all coasts but at its most diverse in southern Australia. All species have one Echinopsis Cactus or Hedgehog cactus. This cactus is at least 30 years old. It belonged to my mother who died in 1999 and it languished in my Dad's porch for years.
