Apterodontinae ("without winged tooth") is an extinct subfamily of hyaenodonts from extinct paraphyletic family Hyainailouridae, specialised for aquatic, otter-like habits.{{cite journal |last1=Laudet |first1=V. |last2=Grohé |first2=C. |last3=Morlo |first3=M. |last4=Chaimanee |first4=Y. |last5=Blondel |first5=C. |last6=Coster |first6=P. |last7=Valentin |first7=X. |last8=Salem |first8=M. |last9=Bilal |first9=A.
