The existence of an intrarenal renin‐angiotensin system (RAS) in a perfused European lesser‐spotted dogfish __Scyliorhinus canicula__ trunk preparation was examined by the inhibition of angiotensin‐converting enzyme by captopril. This resulted in a glomerular diuresis, an increase in urea and chlori

✦ Synopsis
In the European lesser‐spotted dogfish Scyliorhinus canicula, rectal gland mass in mg (M~Rg~) followed the allometric relationship: M~Rg~ = 1·15__M__^0·68^, where M is body mass (g). The concept of allometric scaling is an important consideration in studies investigating the function of osmoregulatory organs.
