The PI in our lab teaches a upper division college Vertebrate Biology
course. When I took this particular course from the previous professor who
has since retired, we had one dogfish per every two students in a class of
100 that was taught every year. When the new professor took over the
course, he discontinued the use of dogfish for labs. The students now get a
lab-reared zebrafish, Danio rerio, to look at. (ok, it IS a tad
smaller....gets those motor skills honed!). I'm very proud of him. He also
discontinued the use of other vertebrate preps that had been harvested from
the wild specifically for teaching biology. He never fails to point out to
the class the irony of biologists taking threatened organisms for
classes....this is the type of lesson I would hope biology students take
away with them!
