Four "dwarf sirens" hatched at the Detroit Zoo’s National Amphibian Conservation Center in recent weeks. Dwarf sirens are a species of salamander that rarely reproduce in captivity.
In a statement, Dr. Ruth Marcec said, “These animals are very difficult to breed in captivity – it typically takes changing the ion content of the water to mimic dilution from rainfall. Now that we’ve established that this is possible, we are very excited to increase the dwarf siren population at the Detroit Zoo.”
This is a big step for the dwarf siren salamander (especially considering the amphibians only have two legs so big steps are difficult).
