Spinal　cord　injuries　(SCI)　are　a　Gordian　knot　for　concerned　scientists.　Many　species　of　animals　have　been　used　to　study　their　repair　mechanisms.　In　the　core　research　area,　most　experiments　use　rabbits,　rats,　mice,　dogs,　and　pigs.　These　animals　pose　some　problems,　such　as　high　costs　and　difficultly　of　postoperative　care.　Finding　a　promising　animal　model　with　the　advantages　of　frequently-used　animal　models,　while　avoiding　disadvantages,　is　important　and　urgently　required　to　understand　underlying　neurodegenerative　mechanisms　of　SCI.　Zebrafish,　due　to　certain　characteristics,　have　attracted　more　and　more　attention.　This　review　introduces　the　basic　features　and　advantages　of　zebrafish,　making　it　a　promising　animal　model　that　will　play　a　significant　role　in　the　study　of　SCI　in　future　research.
