In russell's speech about his hobby as an amateur taxidermist, he exhibited several mounted animals as his presentation aids. which type of presentation aid did russell use?

The answer is "props".

"Prop" originates from the expression "theatrical property". On the off chance that you watch a play, props are objects utilized by performing artists in front of an audience to add authenticity to the story and to help advance the account. Regular props that are utilized in a play incorporate tables, seats, lights, umbrellas. The rundown continues forever.  

In a presentation, props are objects that the speaker uses to upgrade the effect of an introduction. The extent of the prop is restricted just by the span of the stage. Most props are little enough to be dealt with by the moderator.
