Chondrocladia lyra
''Chondrocladia lyra'', also known as the lyre sponge or harp sponge, is a species of carnivorous deep-sea sponge first discovered off the Californian coast living at depths of by Welton L. Lee, Henry M Reiswig, William C. Austin, and Lonny Lundsten from the Monterey Bay Aquarium Research Institute (MBARI).〔(【引用サイトリンク】url=http://www.catalogueoflife.org/col/details/reference/species/13160377 )〕
The species was listed among the ''Top 10 New Species 2013'' discovered in 2012 as selected by the International Institute for Species Exploration at Arizona State University out of more than 140 nominated species. The selection was publicised on 22 May 2013.
== Structure ==
''C. lyra'' is named the harp sponge because its basic structure resembles a harp or lyre. It is a sessile organism which anchors itself to the soft seafloor using a rhizoid, a root-like structure that embeds into the sea floor. From the top of the rhizoid, 1 to 6 horizontal, equidistant stolons with vertical branches form the 'vanes' of the sponge (this is evident in all of Chondrocladia). Depending on the number, the vanes display pentaradiate, tetra radiate, or biradiate symmetries.〔(【引用サイトリンク】url=http://onlinelibrary.wiley.com/doi/10.1111/ivb.12001/abstract )〕 The vanes give ''C. lyra'' its harp-like structure and these are covered in velcro-like hooks and spines, which it uses to snare prey that drift past it in currents. Of the specimens found, the largest recorded is nearly 60 centimeters in length.
