from man shells(4)

     The  following  default  shells  are  used   by   utilities:
     /bin/bash,   /bin/csh,   /bin/jsh,   /bin/ksh,   /bin/pfcsh,
     /bin/pfksh,   /bin/pfsh,   /bin/sh,   /bin/tcsh,   /bin/zsh,
     /sbin/jsh,     /sbin/sh,     /usr/bin/bash,    /usr/bin/csh,
     /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh,  /usr/bin/pfksh,
     /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh.
     Note that /etc/shells overrides the default list.

無くても良いようです。
