I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">large animals</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that elephant is a subclass of big Animalia)</span><br/ ><br/ >This is all the clue.<br/ ></span>
