the Human Fish

plot
Raeburn sends the crew of Galasphere 347 to investigate the Magda Ocean on Venus, where the Tula fish are evolving at an unusually high rate, developing almost human physical characteristics, thus posing a serious threat to the planet’s other inhabitants.  There they discover an underwater barrier made from polydon, a construction material which is being dumped into the ocean.  Realizing that the cosmic radiation emitted by the material is the cause of the Tulas’ accelerated evolution, Dart plants depth charges to destroy the barrier.  The Tulas, however, disconnect them from the detonator before Dart can set them off.  Dart and his crew use sedatives to render the fish unconscious before relaying the depth charges and successfully destroying the polydon barrier.

notes
This is the first time we see Slim’s home planet, Venus.
