One example of this is Tedania klausi which shares the bright orange coloring with T. Tedania ignus can be difficult to differentiate from other species in the same family. The diameter of the ostial openings are 3.5-14.0 µm. Tedania ignus has spicules ranging in size from 50-270 µm in length and 32.-9.8 µm in width. ignus are smooth with curved styles and the tylotes are straight with microspined ends. The shape and size of spicules are a major characteristic used for classification and identification of sponges. Oscula are scattered throughout the organism. They are sessile, growing in low mounds extending in all directions, approximately 1 cm thick. In general fire sponges are conspicuous with a bright orange color. ( Engel and Pawlik, 2005 Maldonado and Young, 1996 Pawlik, 1998) ignis generally hides in cryptic locations under patches of coral rubble due to the increase in predation by fish. When in association with a reef habitat T. Tedania ignis are found in two general habitats: amongst red mangrove roots and in coral reefs. They usually live at depths between 0.5-2 m. ( Wulff, 2006)įire sponges are found in shallow tropical waters with a relatively slow but steady water flow.
ignis in the Southern Pacific near Hawaii however these are unconfirmed and could be attributed to the difficulty of classifying species within the family Tedaniidae. The southernmost population exists off the coast of Brazil and extend as far north as South Carolina. The range of Tedania ignis, common name fire sponge, is primarily in the Neotropical Region however, there are significant populations in the southern Neartic Region.
