External Stomach (Ex)

A giant starfish ejects its stomach in order to begin digestion of a captured meal. It deals damage to a grappled creature as if it had the swallow whole ability, except a creature cannot cut its way free from the starfish’s gullet.

Tube Feet (Ex)

Seastars move and grapple using thousands of shorter appendages filled with fluid and ending in tiny suctions cups. They treat any solid surface as flat terrain and use their total HD instead of their base attack bonus to determine their CMB and CMD when grappling an opponent.


Environment any ocean
Organization solitary, pair, or field (3-60)
Treasure none

Some starfish contend with a greater number of more dangerous marine threats than on other worlds. Their resulting evolution produced faster, stronger specimens that recover from injury very quickly. Most unique among the species is that seastars have no agenda or reproductive mechanism other than to split and regenerate after attacked by predators. Ironically, the number of natural enemies that find them delicious ensures their survival.

Seastars have mouths on both sides of their bodies, allowing them to crawl towards stationary food, or to lies half-buried in sand to ambush prey crawling across the seabed above them. The average seastar is 7 feet in diameter and weighs 600 pounds.
