''Arthuria canariensis'', commonly known as the yellow calcareous sponge, is a species of sponge in the family Clathrinidae. It is found in shallow seas in the Canary Islands, Cape Verde, the Adriatic Sea and the Caribbean Sea. The specific epiphet "canariensis" was given to this species because it was first described from Lanzarote in the Canary Islands.〔 ==Description== ''Arthuria canariensis'' has a small, lacy structure and is a bright lemon yellow colour. It is an asconoid with many tiny flask-like tubes. Water is drawn in through fine holes near their base, the ostia, moved along by flagella and expelled from the osculi at the top, each osculum being a single exit formed from many fused ascon tubes. The skeleton is composed of large calcareous spicules called megascleres, made predominantly of calcite, forming a soft, fragile, supporting network. The whole sponge can grow to in diameter. Small individuals form tufts but larger ones have gentle folds, with osculi along their ridges.
