Clathrina blanca
Introduction '''''Clathrina blanca''''' is a species of Calcareous sponge in the genus Clathrina.It was discovered in 1867 and published in 1868 by Nicholas Miklouho-Maclay, on an expedition to the Canary Islands with Ernst Haeckel. Miklouho-Maclay classified it as ''Guancha blanca''; the species name refers to its "lustrous white color", and the Guanches were indigenous people of the Canaries. Haeckel soon after recategorized it into seven different genera, including ''Ascetta blanca''. Multiple rediscoveries in different locations with different names followed, including ''Ascetta macleayi'' from Australia (Von Lendenfeld 1885), and ''Leucosolenia stipitata'' from Victoria (Dendy 1891). It has also been observed in California, and since 1937 it has been classified as ''Clathrina blanca''.
