Extract

The hydrostatic permeability of the aboral integument of the starfish Asterias rubens L. was found to be 5·1 ± 2·1 × 10−6 cm3/cm2/s/cm H2O. A sudden increase in permeability around 5 cm water pressure was found to coincide with the bursting of the dermal branchiae.

The area of protracted dermal branchiae per cm2 of aboral integument has been estimated and, if only this region represents the permeable areas of the skin, the above figure may well rise to 1 × 10−5 cm3/cm2/s/cm H2O.
