The　oceans　process　abundant　resources　necessary　for　human　production　and　livelihood,　yet　the　complex　and　variable　marine　environment　has　continued　to　limit　human　capability　in　detecting　and　utilizing　these　resources.　Inspired　by　the　excellent　mobility　of　marine　life,　biomimetic　robotic　fish　have　emerged　as　a　new　type　of　autonomous　underwater　vehicle　over　the　past　three　decades.　In　early　reviews　of　robotic　fish,　researchers　classified　and　discussed　based　on　the　fish　species　and　their　morphologies.　The　challenging　problems　and　technological　prospects　of　robotic　fish　are　not　revealed　thoroughly　due　to　countless　species.　To　provide　a　comprehensive　overview　of　the　latest　research　advancements,　we　make　a　classification　focusing　on　the　integrated　mechatronic　designs　of　robotic　fish.　Specifically,　eight　hot　topics　concerning　the　propulsion　mechanisms　and　structural　designs　of　robotic　fish　have　been　broadly　defined　from　literature　screened　with　PRISMA　process　over　the　past　decade,　with　representative　seminal　works　in　each　topic　being　analyzed.　Furthermore,　this　review　also　introduces　the　latest　advances　in　underwater　perception　and　autonomous　technologies　for　biomimetic　robotic　fish,　and　provides　an　outlook　on　their　future　development.　It　is　expected　that　by　summarizing　the　latest　achievements,　researchers　can　be　inspired　with　novel　mechatronic　designs　to　further　promote　the　practicality　research　of　robotic　fish.
