  1. Decapod Tree of Life Keith Crandall Brigham Young University

  2. The PIs • Keith Crandall, BYU • Darryl Felder, University of Louisiana • Rod Feldmann, Kent State University • Nikki Hanegan, BYU • Jody Martin, LA County Natural History • Carrie Schweitzer, Kent State University

  3. The Scope • Over 15,000 species • 179 families • 152 extant, 27 known only from fossils • 62,000 species of Crustaceans • 849 families compared to 879 families of insects • >20% of Crustacean species and families

  4. Current Taxonomy • Class Malacostraca • Order Decapoda • Suborder Dendrobranchiata (7 families) • Suborder Pleocyemata (7 infraorders) • Stenopodidae (2 families) • Caridea (37 families; shrimp) • Astacidea (7 families; clawed lobsters & crayfish) • Thalassinidea (12 families; mud shrimp) • Palinura (5 families; spiny lobsters) • Anomura (16 families, hermit crabs, king crabs) • Brachyura (75 families; true crabs) “Rearrangement of the subtaxa within this order is a popular carcinological pastime, and the classification is far from being stable.”

  7. Astacidea Astacidea Thalassinidea Palinura Achelata Reptantia Pleocyemata Anomala Thalassinidea Brachyura Brachyura Stenopodidea Caridea Dendrobranchiata Anomura Porter et al., 2005 Crandall et al., 2000 Brachyura Anomala Thalassinidea Astacidea Glypheidea Achelata Polychelida Ahyong and O’Meally, 2004 Even More!

  8. The Goal • Comprehensive taxon sampling across all 179 families • Morphology • Molecular data from 20 genes across 152 extant families • Some dense sampling below the species level where available data permit and/or taxonomic problems exist

  9. New Discoveries • March 8, 2006 new family • Kiwa hirsuta - family Kiwaida (Goddess of crustaceans in Polynesian mythology) • 2,300 m (7,540 ft) - 1,500 km south of Easter Island

  10. How do ATOLs and CBOL relate? • Complimentary • Can inform one another • Highly antagonistic! • Need to bring these communities together

  11. How can you help the ATOL? • Send Specimens! • Let us know about cruise opportunties • We’re happy to barcode for you and we’ll sequence other genes too and provide a robust systematic framework for your species IDs
