What is the largest starfish in the world?
The worlds heavyest starfish is known only by its latin name Thromidia Catalai. It can reach over 6kg and be 63cm across.
Despite having no widely accepted common name, it is sometimes known as the "fat star".
The largest starfish in terms of span is also known only by its latin name of Midgardia xandaros. It is a filter feeder, and can reach 1.4 metres across, but it is very slender.
The generally accepted largest sea star in terms of sheer size is the sunflower sea star, or giant sun star Pycnopodia helianthoides. It often reaches 1 metre across, smaller than the Midgardia xandaros in terms of actual span, but far more massive. It can have up to 26 arms.
It is closely followed by the Crown-of-Thorns starfish. People have reported sighting some as big as 700mm in diameter from one tip to another. The normal size for a starfish is between 250mm to 350mm.
