Abstract

Vascular corrosion replicas of the counter current heat exchanger microcirculation in skipjack tuna, Katsuwonus pelamis, were examined by scanning electron microscopy. Smallbore (7–10 μm diameter) vessels, with characteristics typical of those associated with the secondary circulation, were abundant in the central and lateral heat exchangers. These vessels arise from the large‐bore (70 μm diameter) retial arterioles and, after a tortuous path, anastomose repeatedly to form 50–200 μm diameter secondary collecting vessels which ultimately exit from either pole of the rete. © 1994 Wiley‐Liss, Inc.
