T. californicus is one of the jumping spider species that occupy sandy beaches. Their size range is 3.0mm to 5.0mm. They are commonly seen in spring and summer months, but their size and crypsis makes them difficult to find. These spiders have a wide color variation and can be easily confused with the other salticid spider H. amicus. These spiders range from 3.0mm to 5.5mm and have a cephalothorax that is smaller than their abdomen, in contrast to H. amicus. They can be seen darting around the beach or under kelp wrack, in search of smaller flies and beetles.
