  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 ...

    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. 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].

  6. 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]

  7. 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.

    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. Calcareous sponge - Wikipedia

    en.wikipedia.org/wiki/Calcareous_sponge

    All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small ...
