This educational film was produced for the Devry Educational Schools, then in New York and Chicago, but later much spread out. It was probably the first of the well-known "Colleges for Profit" although, of course, there were many places that might teach a paying student a trade or skill.
In any case, this film concerns itself with three random species from a river: a salmon, a stickleback and a crayfish. It is well edited, but somewhat distracted in what it is trying to tell the audience, starting out with a salmon hatchery and winding up with a crayfish growing back a claw. The version I saw was complete; the piece is supposed to be 9 minutes long and I looked at one that time in just six seconds short of that. So.... "Here are three types of marine animals."
