“…In contrast, in the Port Jackson shark (Heterodontus portusjacksoni), Stokes & Firkin (1971) found that a greater number of yeast were ingested by neutrophils than by eosinophils, with an average of six and two per cell, respectively. Phagocytic cells of the smooth dogfish (Mustelus canis) were found to resemble polyorphonuclear leucocytes (Weissman et al, 1978). In other studies with nurse shark cells, only the neutrophils, not the eosinophils, were reported to be phagocytic (Hyder et al, 1983).…”
