Nothing easier than that!
A trip to the Aquarium of the Pacific in Long Beach brings one right into the most spectacular octopus’s gardens imaginable.
What Old Grumpy and friend are lacking in color, they more than make up in size.
If that isn’t enough, one can always pet a Manta ray or a shark.
Now I can distinguish a shark (small) from a Manta ray (huge) by touch alone – and yes, it is a completely different tactile experience.
