Etymology: Trematomus: Greek, trematos = hole + Greek, tomo = section, cut (Ref. 45335); pennellii: Species name pennellii honors Harry LL Pennell, captain of the ship Terra Nova of Scott's British Antarctic Expedition of 1910 (Ref. 45168).
Eponymy: Commander Harry Lewin Lee Pennell, R.N. (1882–1916) served (as Navigator, at the time he was a Lieutenant) on the ‘Terra Nova’, British Antarctic Expedition (1910–1913). He died during the Battle of Jutland. (Ref. 128868), visit book page.
