Boyd’s Bible Dictionary:
(twisted-foot). A faulty rendering. The Septuagint has “land-crocodile,” and doubtless one of the large lizard species is meant (Lev. 11:29).
Concise Bible Dictionary:
One of the unclean animals. The Hebrew word is supposed to refer to a lizard, but to what species is not known: perhaps the dhab of the Arabs, a large lizard. The RV has “great lizard.” The tortoise, however, is common in Palestine (Lev. 11:29).
