  • Paleontologist Javier Luque discovered a new type of animal - Callichimaera perplexa - which was a weird, quarter-size crab with crazy body parts.
  • It lived around 90-95 million years ago and had a shrimp mouth, frog crab claws, a lobster shell, paddle-like appendages of a sea scorpion, and soccer-ball sized eyes.
  • It also combined baby and adult parts - grown individuals had bent claws, leg-like mouth parts, an exposed tail, and a long body, all seen in crab larvae.
  • This discovery shows that crabs have lost and reevolved their body plans many times throughout history.

  • It spread across the world during the Miocene with other hyaenodonts - an extinct lineage of carnivores.
  • The biggest impact of this finding is that it will help paleontologists define the timeline for these animals more precisely.
