The salamanders have been crossing the road every morning this week. I always wonder just where they are heading. One might imagine that the meadow on either side of the lane is certainly big enough for anything a salamander wants but apparently not. I can recall pretty clearly that in high school we studied flat worms for one of our sections. Flatworms are pretty amazing when you think about how vulnerable they seem. They are predaceous on other, less fortunate animals the flatworms encounter while slithering about under rocks and logs and wet areas. Flatworms even feed on earthworms and slug and snail eggs! [Yay!] Some aquatic flatworms even feed on mosquito larvae! Flatworms are interesting because they have wonderful powers of regeneration. If you cut a flatworm crosswise, the tail end will grow a new head and the head end will grow a new tail. If you cut them lengthwise, each side regenerates another. If you cut the head in two lengthwise but leave the body intact, the worm will grow two heads. Those were some of the experiments we did in lab.
