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. Symbiotic bacteria that normally inhabit sea sponges start reproducing at an unsustainable rate when ambient temperature of the water increases by a few degrees.
Sponges or sea sponges are primarily marine invertebrates of ... species, ranging in habitat from tidal zones to depths exceeding 8,800 m (5.5 mi), though there are ...
The crumb-of-bread sponge is found in the northern Atlantic Ocean, the Mediterranean Sea and the Pacific Ocean, as well as around the southern African coast from the northern Cape to Port St Johns. It lives from the intertidal zone in tide pools to a maximum depth of about 15 meters (about 50 feet).
Hexactinellid sponges require a hard substrate, and do not anchor to muddy or sandy sea floors. [6] They are found only where sedimentation rates are low, dissolved silica is high (43–75 μM), and bottom currents are between 0.15 and 0.30 m/s. [5] Dissolved oxygen is low (64–152 μM), and temperatures are a cool 5.5-7.3 °C at the reefs. [5]
Spongia officinalis, better known as a variety of bath sponge, is a commercially used sea sponge. [2] Individuals grow in large lobes with small openings and are formed by a mesh of primary and secondary fibers. [3] [2] It is light grey to black in color. [3] It is found throughout the Mediterranean Sea up to 100 meters deep on rocky or sandy ...
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 ...
Spheciospongia vesparium, commonly known as the loggerhead sponge, [2] is a species of sea sponge belonging to the family Clionaidae. While it is highly toxic to many fish, this sponge is eaten by certain angelfish and is known to form part of the diet of the hawksbill sea turtle ( Eretmochelys imbricata ).
A handful of centuries-old sponges from deep in the Caribbean are causing some scientists to think human-caused climate change began sooner and has heated the world more than they thought. Other ...
