NAS - Nonindigenous Aquatic Species

NAS logo - click to go to the NAS home page Sponges (Phylum Porifora) are sessile organisms usually found in marine waters, although a few species do live in fresh water. Standard methods of introduction include ship fouling or transportation in ballast water of ocean-going vessels. Potential impacts include competition with native species for suitable substrate and negative effects on organisms to which they attach. An example of an introduced sponge is Bowerbank's Crumb of Bread sponge, Halichondria bowerbanki. This sponge was introduced to the west coast with commercial oyster plantings. So far, its impacts are unknown.
