## Abstract The nurse shark, __Ginglymostoma cirratum__, is an obligate suction feeder that preys on benthic invertebrates and fish. Its cranial morphology exhibits a suite of structural and functional modifications that facilitate this mode of prey capture. During suctionβfeeding, subambient press
Using radio-isotopes, the turnover rates of sodium, chloride, water, and urea were measured, at different salinities, in the pyjama shark, Poroderma africanum (Gmelin). The exchangeable ionic space was also measured. Sodium turnover was O.24%/h in normal sea water (467 mM Na/l, 550 mM CI/I, 1020 mOs
