  1. Fish Friday #3 - October 10, 2008 1. Test Details 2. Sign Up for Paper Topics - Due on 10/27 3. Protacanthoperygii - Dustin & Ryan 4. Stenopterygii & Cyclosquamata

  2. Test #1 Details Overall Average = 43.7 + 5.6 (SD) --> 87.4% However, differences between grads and undergrads. Grad Mean = 48.7 + 2.4 (SD) --> 97.4% Undergrad Mean = 41.0 + 4.9 (SD) --> 82.0%

  3. Where we are in the big scheme.

  4. Sternopterygii - bristlemouths, marine hatchetfish, light fishes, barbeled dragonfishes, jellynose fish bristlemouth barbeled dragonfish or viperfish jellynose fish

  5. bristlemouths -most numerically dominant group in terms of numbers of individuals of any vertebrate - large mouths that extend past the eye -elongate, but not compressed -have numerous small teeth, but also fine gill rakers -- can eat both fish and smaller zooplankton

  6. hatchetfish -photophores point down and are thought to function in countershading -males may use them in mating -thinness makes them hard to see head on -also very abundant -move up and down in water column

  7. hatchetfish

  8. barbeled dragonfish -lures often bioluminescent thought to be involved in hunting -large, fang-rich mouths allow them to eat fish bigger than themselves

  9. more barbeled dragonfish, loosejaws, viperfish (same group)

  10. Cyclosquamata -Cyclosquamata means “circle scales”. -telescopefishes, greeneyes, tripodfish, lizardfish, daggertooth, lancetfishes - group is united by unique structures in the gill arches and pelvic girdle - swimbladder is usually absent

  11. tripod fish - elongate pectoral, pelvic, and caudal rays - used to rest on the bottom -deep sea

  12. daggertooth - many fish families in this group are similar (barracudinas, sabertooth) -extremely large jaws and teeth - important in marine food chains eat smaller fish, but are themselves eaten by tuna and swordfish

  13. lancetfish - large, sail-like dorsal fin -large (up to 2m) - most others in this group are small -lots of teeth in big mouth

  14. lizardfish - benthic fishes (live on bottom) - most found in shallow water 2 sp. are deep - common around coral reefs - sit and wait, ambush predators
