A relaxin-like peptide, previously referred to as “Gonad Stimulating Substance”, has also been found in this starfish. There is evidence that the peptide is involved in reproductive processes and functions via a G protein-coupled receptor , which supports its relatedness to vertebrate relaxins.
Like other starfish in the family Asteriidae, Marthasterias glacialis is a predator and feeds mostly on bivalve molluscs and other invertebrates. [6] It has been found that secondary metabolites known as saponins , found within the starfish's tissues, have a dramatic effect on the whelk Buccinum undatum .

Pentaceraster cumingi, sometimes known as the Panamic cushion star, Cortez starfish or knobby star (a name also used for other species), is a species of starfish in the family Oreasteridae. It is found in warmer parts of the East Pacific ( Gulf of California to northwest Peru , including offshore islands like the Galápagos ) and in Hawaii . [ 1 ]
The species is also considered in reef aquariums. It feeds on the surface of the stones in thin layers of algae, so it can live only in an old well-ripened aquarium. If the algae are not growing fast enough, supplemental feeding is usually unsuccessful, and this starfish dies of starvation.
Culcita novaeguineae (common name, cushion star) is a species of starfish. It has short arms and an inflated appearance and resembles a pentagonal pincushion . It is variable in colour and can be found in tropical warm waters in the Indo-Pacific .
