"Enter the nocturnal Pentalagus furnessi, or Amami rabbit, the world’s only dark-furred wild bunny. In a study published this week in the journal Ecology, Dr. Suetsugu and Hiromu Hashiwaki, a co-author also of Kobe University, posit an evolutionary bargain between Amami rabbits and B. yuwanensis. The root-sucking plants give food in exchange for seed dispersal services — something that has never been documented between a mammal and a parasitic plant."
