Let me join it. I've done no thorough research, but I feel like the same can be said to many other
verb-pairs, one transitive with -aru ending and the other intransitive with -eru, like

曲げる to bend something (transitive)
曲がる something bends (intransitive)

閉める to close something (transitive)
閉まる something closes (intransitive)

当てる to hit something (transitive)
当たる something hits (intransitive)

浸ける to sink something (transitive)
浸かる something sinks (intransitive)

変える to change something (transitive)
変わる something changes (intransitive)

the list is almost endless.
