Semi-realistic creatures I'm developing for a personal project. :) They exist on a parallel version of Earth that is three times as large, and is so able to support a much more diverse and weird range of animal species. An intrepid space exploration team approaches the planet, but while in orbit a mysterious accident causes the ship's debris shields to deactivate, and the ship breaks up into pieces, scattering its remains, along with the crew, all over the massive planetoid!
