... conditions in their midgut with the underlying epithelial transport mechanisms being largely unknown. Using ion-selective microelectrodes, the present study demonstrated that pluteus larvae of the purple sea urchin have highly alkaline pH (pH ∼9) and low [Na + ] (∼120 mmol l −1 ) in their midgut fluids...

... use the scanning ion-selective microelectrode technique to measure efflux and influx of K + , H + , Na + and Ca 2+ in intact worms. Transport of ions into, or out of, immobilized worms produces small gradients in ion concentration in the unstirred layer near the surface of the worm. These gradients...
