These sponges are one of the only true sustainably farmed sea sponges in the world. [5] The sponges are farmed via the rope method, with low investment costs of a few thousand dollars for farming and maintenance equipment, producing 100% natural sponges with no harsh chemicals added during processing.

Sponges or sea sponges are primarily marine invertebrates of ... are restricted to polar regions and the ocean depths where ... Leuconid sponges grow to over 1 m (3.3 ...
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]
Resulting sponge larvae disperse with ocean currents, but there is some genetic differentiation among populations from Florida, the Bahamas and Belize. [12] Growth models for X. muta have been formulated from digital photographs of the same sponges over a period of 4.5 years. [5] Sponge growth rates ranged from over 400% per year to only 2% per ...
The latest find is fossil-feeding sea sponges. Scientists are discovering alien-like worlds in the uncharted oceans of the Arctic and Antarctica. The latest find is fossil-feeding sea sponges.
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).
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 ...
Ocean sponges suggest Earth has warmed longer, more than thought; some scientists dubious ... Many sponge species live long, and as they grow they record the conditions of the environment around ...
