The deep-sea ecosystem engineer Geodia barretti (Porifera, Demospongiae) maintains basic physiological functions under simulated future ocean pH and temperature conditions

This study examines the physiological response of the deep-sea sponge Geodia barretti to simulated future ocean conditions and finds no significant effect on metabolic indicators, though tissue necrosis is observed.

Dissolved organic carbon (DOC) is essential to balance the metabolic demands of four dominant North-Atlantic deepsea sponges

This study shows that dissolved organic carbon (DOC) meets most of the metabolic needs of deep-sea sponges, enabling them to thrive in nutrient-poor environments.
