Luidia magnifica
A large, fast-moving starfish with variable colors and up to 11 arms.
Luidia magnifica, commonly known as the magnificent star, is a species of starfish in the family Luidiidae. It is found in the Pacific Ocean, particularly on sandy seabeds surrounding Hawaii and the Philippines. This species is notable for its large size, rapid movement, and variable coloration.

Lore & Background
The magnificent star usually has 10 long, tapering arms with pointed tips, though occasionally 11 arms are present. One or more arms may be regenerating after damage or removal by a predator. The upper surface is covered with paxillae—pillar-like spines with truncated ends—and there are also paxillae on the margins of the underside. Multiple rows of tube feet run down the center of each arm. Color is variable: some specimens are creamy yellow with bands of red spots, while others are darker in shades of brown and olive. The underside is usually creamy yellow, and the tube feet are tipped with red.
This species can grow to a large size; one specimen on the Pearl and Hermes Atoll, Hawaii, measured 84 centimeters (33 inches) in diameter. It is found on sandy areas of the seabed surrounding Hawaii and the Philippines at depths between 18 meters (59 feet) and 133 meters (436 feet).
Reader's Guide
Luidia magnifica is a significant species within the family Luidiidae due to its large size and distinctive appearance. Like other members of the genus Luidia, it is likely an opportunist predator of macrofauna and possibly also a scavenger. Related species favor a diet of bivalve molluscs and echinoids. The magnificent star can move rapidly, appearing to glide across the sandy seabed. It swallows large items of food whole, digesting them in its two stomachs and further processing the remains in the pyloric caeca in the base of its arms. Undigested material is then ejected through its anus. Its presence in the Pacific Ocean, particularly around Hawaii and the Philippines, and its variable coloration make it a notable subject for marine biology studies. The species' ability to regenerate arms and its rapid gliding movement contribute to its ecological role as a predator and scavenger in sandy seabed habitats.
