Sealskin
From BibleEncyclopedia.Net
sēl´skin:
The rendering of the Revised Version (British and American) (Exodus 25:5; Ezekiel 16:10) for עור תּחש, ‛ōr taḥash, the Revised Version margin “porpoise-skin,” the King James Version “badgers' skin.” A seal, Monachus albiventer, is found in the Mediterranean, though not in the Red Sea, but it is likely that taḥash means the dugong, which is found in the Red Sea.
