  2. Sponge - Wikipedia

    en.wikipedia.org/wiki/Sponge

    Glass sponge embryos start by dividing into separate cells, but once 32 cells have formed they rapidly transform into larvae that externally are ovoid with a band of cilia round the middle that they use for movement, but internally have the typical glass sponge structure of spicules with a cobweb-like main syncitium draped around and between ...

  3. Xestospongia testudinaria - Wikipedia

    en.wikipedia.org/wiki/Xestospongia_testudinaria

    Xestospongia testudinaria is a species of barrel sponge in the family Petrosiidae. More commonly known as Giant Barrel Sponges, they have the basic structure of a typical sponge. Their body is made of a reticulation of cells aggregate on a siliceous scaffold composed of small spikes called spicules.

  4. Sponge spicule - Wikipedia

    en.wikipedia.org/wiki/Sponge_spicule

    This sponge develops the also largest known bio-silicate structures, giant basal spicules, three metres high and one centimetre thick. With such spicules as a model, basic knowledge on the morphology, formation, and development of the skeletal elements could be elaborated.

  5. Demosponge - Wikipedia

    en.wikipedia.org/wiki/Demosponge

    The earliest sponge-bearing reefs date to the Early Cambrian (they are the earliest known reef structure built by animals), exemplified by a small bioherm constructed by archaeocyathids and calcified microbes at the start of the Tommotian stage about 530 Ma, found in southeast Siberia. [11]

  6. Chondrocladia lyra - Wikipedia

    en.wikipedia.org/wiki/Chondrocladia_lyra

    Chondrocladia lyra is named the harp sponge because its basic structure resembles a lyre or harp. 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.

  7. Clathrinida - Wikipedia

    en.wikipedia.org/wiki/Clathrinida

    These sponges have an asconoid structure and lack a true dermal membrane or cortex. The spongocoel is lined with choanocytes. One of the most famous species of Clathrinida is lemon sponge, featuring a bright yellow color and a slightly elongated-globular growth form [7].

    They then tested the sponge in four different water samples, taken from irrigation water, pond water, lake water and sea water, and found it removed up to 99.9% of microplastics, according to a ...

  9. Choanocyte - Wikipedia

    en.wikipedia.org/wiki/Choanocyte

    This improves both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products. Although all cells in a sponge are capable of living on their own, choanocytes carry out most of the sponge's ingestion, passing digested materials to the amoebocytes ...
