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.

It is the SUNFLOWER STARFISH.The sunflower starfish (Pycnopodia helianthoides) is a large predatory starfish usually with 16-24 limbs called rays. It is the largest starfish in the world. Sunflower starfish can grow to have an arm span of 1 meter (3 ft 3 in) in diameter.The color of the sunflower starfish ranges from bright orange, yellow and red to brown and sometimes to purple, with soft, velvet-textured bodies and 16-24 arms with powerful suckers. Most starfish species have a mesh-like skeleton that protects their internal organs. Easily stressed by predators such as large fish and other starfish, they can shed arms to escape, which will grow back within a few weeks. They are preyed upon by the king crab.
