What a killi ?


Killifhishes in brief

The term "killi" comes from the old Dutch "kil", meaning small stream. It would have been assigned by the settlers arriving in North America, watching the fish in these rivers. This word was subsequently generalized and extended to all toothcarp oviparous (Cyprinodontes ovipares).

Currently, there are over 800 species of killifishes, belonging to several gender as Aphyosemion, Fundulopanchax, Notobranchius, Rivulus and others. Considered part of the finest specimens of freshwater, killifishes fascinated also by their amazing adaptability to the environment. Note particularly the building:

  • to move from one place to another, skipping;
  • to stay out of water for many minutes or hours;
  • to accommodate the lack of food for several days;
  • but above all, a non-standard mode of reproduction. While some species do not know the drying of the stream where they are, others live in temporary ponds. At the beginning of the dry season, ponds are disappearing, the eggs are buried in the ground, and resist until the next rainy season, after many months!
