These bugs are common in my house. They look like little crustaceans and they can jump and are tough. What is this bug??

This one has us a bit stumped. We are pretty sure it is not a Silverfish, which is pictured on BugGuide. Furthermore, Silverfish do not jump and they are not tough. They practically disintegrate when smashed. This looks more like a Crustacean, and it appears to be a Terrestrial Amphipod, but it does not appear to be a Lawn Shrimp or House Hopper, a usual suspect. Perhaps one of our readers will have a better idea. How close are you to the shore? Where in Southern California are you located?
Correction: Thanks to Juliet who quickly directed us to Jumping Bristletails on Wikipedia. We found this matching image on BugGuide. According to BugGuide: “short lateral styli (rudimentary appendages) on abdominal segments 2-9; able to jump up to 10 cm by snapping abdomen against ground.” It was those lateral styli that led us to question if this might be a crustacean.
