    A group of fish called bristlemouths apparently are the most common vertebrate on Earth, number potentially in the quadrillions of individuals.

    By contrast there are a mere 24 billion chickens.

    Are there bristlemouths in any aquariums? With this revelation it seems like they might make an interesting exhibit; also because they are bioluminescent.
