        That's a very unfair and underhanded thing to say. Lissamphibians are good.

      Huh. Amphib systematics are a horrid mess, but does this mean the caecilian lineage simply never really bothered about terrestriality?

      Swimming thru soft moist substrate is OK, but that's not true terrestriality. They don't last long on the surface.
