The pH of water must match that of seawater (pH 7.8–8.4) in order for sponge production to be maximized. Sponges are sensitive to temperature, and extreme fluctuations in ambient temperature can negatively affect the health of sea sponges. High temperatures lead to crashes in sponge cultures.
Your sponge is bacteria's favorite place to grow, which is why you should be replacing it frequently.
Sponges were traditionally distributed in three classes: calcareous sponges (Calcarea), glass sponges (Hexactinellida) and demosponges (Demospongiae). However, studies have now shown that the Homoscleromorpha , a group thought to belong to the Demospongiae , has a genetic relationship well separated from other sponge classes.
Cliona celata, occasionally called the boring sponge, is a species of demosponge belonging the family Clionaidae. [1] It is found worldwide. This sponge bores round holes up to 5 millimetres (0.20 in) in diameter in limestone or the shells of molluscs, especially oysters.
Aplysina archeri, also known as a stove-pipe sponge because of its shape, is a species of tube sponge that has long tube-like structures of cylindrical shape. Although they can grow in a single tube, they often grow in large groups of up to 22 tubes. [2]
If temperature-tracking sea sponges are to be trusted, climate change has progressed much further than scientists have estimated. A new study that uses ocean organisms called sclerosponges to ...
The sponges reached their full extent in the late Jurassic (201-145 million years ago) when a discontinuous reef system 7,000 km long stretched across the northern Tethys and North Atlantic basins. [6] This chain of sponge reefs is the largest known biostructure to have ever existed on Earth. [6]
