Fig. 5. Series of thermograms of the harp seal Jamie. Thermal windows are numbered from cranial to caudal and according to order of their appearance. (A) Arrangement of thermograms recorded after 29 min, 30 min and 32 min. Multiple thermal windows on the seal's trunk have appeared on the left dorso-lateral body side, contralateral to the side the seal is lying on. Thermal windows are solitary and of more or less circular shape; no fusion of thermal windows has occurred yet. The head (Nos. 1, 2) and the hind flippers (No. 13) show high surface temperatures as well, while the left fore flipper shows rather low temperatures. (B) Arrangement of thermograms recorded after 43 min and 45 min. Thermal windows on the seal's trunk have enlarged and partly fused (Nos. 6, 7 and Nos. 8, 9, 10), and new thermal windows have appeared (Nos. 14–16). (C) Arrangement of thermograms recorded after 62 min and 64 min. Thermal windows have further enlarged and fused to more or less coherent areas (Nos. 5–11 and Nos. 12, 13).
