The pectoral and pelvic fins are large and triangular.
The most distinctive feature of Heterodontus marshallae is its color pattern, which consists of 22 dark brown bands and saddles on a light greyish brown background.

The native Tule elk population in the Point Reyes National Seashore faces a dire threat to their existence, and conservationists are making an urgent call for assistance.
For decades, these magnificent creatures have been confined within the boundaries of the National Seashore, unable to roam freely. Their very survival now hangs in the balance.
