Rhabdastrella globostellata

Rhabdastrella globostellata, also known as the yellow pot sponge, is a marine sponge of the order Astrophorida. It is native to many regions of the Indian Ocean including the shores of Madagascar, the Seychelles, and Australia[2] as well as the Malayan Peninsula and Singapore.[3] It was first described by Henry J. Carter as Stelleta globostellata in 1883, named after the globostellate shape of its spicules (Latin globus meaning "sphere" and stellātus meaning "star-shaped").[1]
