"In our study, we focused on the Agelas oroides species, a common Mediterranean sponge that grew throughout the Mediterranean Sea from a depth of less than a meter to 150 meters deep. The remaining six specimens were returned to the sponge gardens from which they were taken and used as a control group. Today, seawater temperatures rise above 29°C (84°F) degrees for three months, which likely causes multi-system damage in sponges and leaves them no chance of recovering and surviving. It is, in fact, these tiny microbes, who the sponges have come to so heavily depend on, that are susceptible to slight rises in temperature [5]. Photo: Neil McDaniel. Who Explore threats of sponges? Boring sponges account for 70% or more of bioerosional damage to skeletons of hermatypic corals in both the Western Pacific and Caribbean regions, accounting for 65–90% of total bioerosion occurring within the first 2 cm of coral skeleton (Highsmist 1981). They can even be found in freshwater aquatic environments such as ponds, lakes, and streams. [1] https://link.springer.com/book/10.1007/978-3-319-09894-4. Individual glass sponges, such as the beautiful Venus's flower-basket sponge (Euplectella aspergillum), are still found in the deep sea but are a different genus and species from the Jurassic reef-builders. The microbe species community within a single sponge is incredibly diverse and abundant, with microbes often accounting for over 40% of the sponge’s volume[4]. "Freshwater sponges were here before the zebra mussel, but not in the abundance that we see them now," Kelch said. These mutually-beneficial relationships have allowed sponges to evolve into many new distinct species with an astonishing variety of shapes, sizes, and forms.
