How well does an octopus remember? Not much is known about their memory. Some say they have a terrific memory while others state that their long term memory (more than 30 seconds) is terrible. In today's experiment, we'll be placing 4 tubes in the experiment tank. We will place a small fish in one of them. The holes will be large enough to allow him to fit an arm through in order to retrieve the food, yet small enough to prevent him from seeing it.

We ran this experiment for 15 days always placing the fish in the same tube to see if he would remember where he usually finds his snack.

The octopus is a very curious animal and can't resist poking around when he finds a hole. In many of the scenes you will notice he places multiple arms simultaneously in the holes. However, try to see if he is favoring a certain one.

This experiment is is by no means going to give us conclusive results but it was interesting to run and does appear to give us some insight on how good his memory is. We'll continue to run this experiment along with many, many more memory experiments.

We would love to hear your thoughts on anything you observe during the video. Although we don't reply to all your comments, we do read them and find value in all of them. The reason we don't reply often is to allow everyone to voice their opinion on each experiment. People tend to view a channel's author as "authority" and this is not the roadmap for OctolabTV. We want to observe and come to conclusions collectively with all of you. We do not want to influence anyone's opinion and observations. This is a group effort and hopefully with multiple octopus memory tests down the road, together, we can come to some very interesting conclusions.
