Yes, there will certainly be a variety of species in heaven--beyond R wildest imaginations!  The animals on this earth were part of God’s original plan & design.   I believe the animal species in heaven will be similar, but have totally different characteristics.  There will be no violence in the animal world, no predators & no victims of prey will be part of the animal kingdom.  Only tame, gentle & loving!  Can’t wait 2 be surprised with God’s animal creations; spending an eternity in exploring, discovering & basking in God’s glorious creations in the new heavens, earth & seas!
