Product Information

It used to be claimed that glass sponges could live on nutrients dissolved in sea water and were very averse to silt. [35] However, a study in 2007 found no evidence of this and concluded that they extract bacteria and other micro-organisms from water very efficiently (about 79%) and process suspended sediment grains to extract such prey. [36] Collar bodies digest food and distribute it wrapped in vesicles that are transported by dynein "motor" molecules along bundles of microtubules that run throughout the syncytium.

An immensely wide variety of shapes and sizes exist. Some have many branches or odd shapes, while others have a simple cylindrical shape. All sponges have tiny pores where they intake water. Inside, they have microscopic hairs, or flagella, which wiggle to push the water through their bodies. Interesting Facts About the Sea Sponge The lifespan of sea sponges can vary significantly depending on their habitat and environment. For example, if a sea sponge inhabits a more temperate, colder ocean, it can see a few years of life. However, when they live in more tropical oceans, such as the Indian Ocean, or deeper waters, they tend to last far longer. Lifespans of up to 200 years have been recorded by scientists, and in incredible circumstances, sponges can live up to 5000 years.

However, it is not always bad news for the sea sponge. They have some defense systems in place to fend off many organisms. Many of these organisms use the sponge to grow and feed on, trying to form a symbiotic relationship. When it isn’t in the best interest of the sponge, however, they release toxins to stop echinoderms and bryozoans from living on them. Esponjas (esponjas de baño)".

PMID 30002868. Sponges with photosynthesizing endosymbionts produce up to three times more oxygen than they consume, as well as more organic matter than they consume. Such contributions to their habitats' resources are significant along Australia's Great Barrier Reef but relatively minor in the Caribbean.

Note the chambers which are connected by short tunnels. Humans use and interact with S. officinalis in a variety of ways. Harvested sponges have been used throughout history for many purposes, including washing and painting. [2] Over-harvesting and sponge disease have led to a decrease in population. [2] [3] [11] Sponge fishing practices have slowly changed over time as new technology has developed and sponge farming is now in use to decrease stress on wild S. officinalis populations. [3] [11] Sponge farming is also recommended as a solution to reducing marine organic pollution, especially from fish farms. [3] [2] [12] [13] Anatomy and morphology [ edit ] Baldacconi, R., et al.
