Abstract
The sea urchin larva has been used by biologists for more than a century to study the development and evolution of animals. Surprisingly, very little information has been generated regarding the physiology of this small planktonic organism. However, in the context of anthropogenic CO2-driven ocean acidification (OA), the membrane transport physiology and energetics of this marine model organism have received considerable attention in the past decade. This has led to the discovery of new, exciting physiological systems, including a highly alkaline digestive tract and the calcifying primary mesenchyme cells that generate the larval skeleton. These physiological systems directly relate to the energetics of the organisms when challenged by OA. Here we review the latest membrane transport physiology and energetics in the sea urchin larva, we identify emerging questions, and we point to important future directions in the field of marine physiology in times of rapid climate change.
