White, yes they are animals (Kingdom Animalia). The approximately 5,000 living sponge species are classified in the phylum Porifera, which is composed of three distinct groups, the class Hexactinellida (glass sponges), the class Demospongia, and the class Calcarea (calcareous sponges).
Hope this helps.

The sponges or poriferans (from Latin porus "pore" and ferre "to bear") are animals of the phylum Porifera. They are primitive, sessile, mostly marine, water dwelling, and filter feeders that pump water through their bodies to filter out particles of food matter. Sponges represent the simplest of animals. With no true tissues (parazoa), they lack muscles, nerves, and internal organs. Their similarity to colonial choanoflagellates shows the probable evolutionary jump from unicellular to multicellular organisms. There are over 5,000 modern species of sponges known, and they can be found attached to surfaces anywhere from the intertidal zone to as deep as 8,500 m (29,000 feet) or further. Though the fossil record of sponges dates back to the Neoproterozoic Era, new species are still commonly discovered.

They both have eukaryotic cells. ( cells that have membrane bound organelles) They're both multiple celled organisms. Sponges have the makings of a nervous system. Neither animals nor sponges have cell walls. Hope this helps.
