  1. Suborder Gobiodei: The Gobies Thomas J Bland Olatunde Akinwale 21 November, 2008 www.eol.org

  2. Gobiodei 9 families, 270 genera, 2211 species Benthic Mostly Marine Small bodied

  3. www.eol.org

  4. Gobiodei Swim bladder absent Pelvic fins below pectoral fins Fused (usually) Lateral line reduced Cephalic canals Can be highly variable among species

  5. Phylogenetics Gobioidei is monophyletic Families are not Thacker 2003

  6. Loach Gobies Family Rhyacicthyidae 1 genus, 2 species Most primitive goby Retains well developed lateral line www.fishbase.org www.eol.org

  7. Freshwater Sleepers Family Odontobutidae 5 genera, 15 species May not be monophyletic www.fishbase.org www.eol.org

  8. Sleepers Family Eleotridae 35 genera, 155 species Marine, brackish, and freshwater Pelvic fins separate Oxyeleotris marmorata reaches 66cm www.nzfreshwater.org www.eol.org

  9. Sand Gobies Family Kraemeriidae 2 genera, 8 species Elongate body Burrow into sand animaldiversity.ummz.umich.edu www.eol.org

  10. Gobies, True Gobies Family Gobiidae 210 genera, >2000 species 10-20 new species/year Round goby (Neogobius melanostomus) animaldiversity.ummz.umich.edu www.eol.org

  11. Wormfishes Family Microdesmidae 5 genera, 20 species Very elongate Burrow into substrate www.fishbase.org www.eol.org

  12. Infantfishes Family Schindleriidae 1 genus, 3 species Highly Paedomorphic Transparent, some bones/cartilage does not develop Lightest, shortest lived vertebrate www.fishbase.org www.eol.org

  13. Round Goby(Neogobius melanostomus) www.eol.org

  14. Round Goby(Neogobius melanostomus) Ballast water introduction www.eol.org

  15. Round Goby High reproductive rate Aggressive Displaces native benthic fishes Eat fish eggs and native mussels Native predator of Zebra Mussel (Driessena polymorpha) animaldiversity.ummz.umich.edu

  16. Shrimp Goby

  18. Mudskippers Subfamily Oxudercinae 10 genera, 39 species Distribution ranges from Tropical and subtropical Intertidal soft-bottomed Shores of West Africa and Indo-Pacific region.

  19. Mudskippers (cont’d) Some species possess adaptations to terrestrial environment and amphibious life. In particular, periophthalms (genus Periophthalmus) and boleophthalms (genus Boleophthalmus) include species that inspired popular and scientific imagination since the dawn of the Natural Sciences.

  21. Questions What adaptations do gobies have for a benthic lifestyle? Why are loach gobies considered the most primitive gobies? Why is Gobiidae so speciose? Why do experts think there may be lots of undiscovered species in Gobiidae? Where is the round goby native to? What role does the goby play in the shrimp goby/shrimp mutualism?
