"Our great concern is that the changes taking place on our shores are a harbinger of what may take place in the future throughout the Mediterranean. “Most worryingly, pumping began to slow within two weeks of exposure to elevated temperatures,” said Stevenson. Long before the dinosaurs who walked the earth 100 million years ago and even longer than jellyfish who have floated around the oceans for 550 million years [1]. Sponges are filter feeders who use flagella lined cells to create a current that pushes water into their internal canals, where they remove small organic particles from the water.

The presence of this steroid biomarker in fossils of known ages confirmed that sponges are one of the evolutionary oldest animals present on our planet today, having survived at least the last 635 million years [3]. They can therefore serve as useful bioindicators of the health of marine ecosystems. Get weekly and/or daily updates delivered to your inbox. staff report. For example, a forecast for rain is a threat to your hair and a lack of an umbrella is a weakness, the two combined are a risk. staff report . The more recent threat of deep-sea mining for metal-rich nodules has been proposed as a new future hazard to sponges.
