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.

Wildlands Network's Chief Scientist, Ron Sutherland, discusses the importance of rewilding efforts and their vision of continental wildways to promote wildlife conservation in North America. Rewilding, a concept rooted in letting nature reclaim its territory, emphasizes the need to reintroduce keystone species to restore ecological balance. Ron explains how rewilding helps to manage ecosystems more efficiently and highlights the case of Yellowstone's wolf reintroduction, which led to a cascade of positive ecological effects.

In a study posted last year, it was found that trophy hunters killed one animal every THREE minutes over the last decade.
The Intergovernmental Panel on Climate Change (IPCC) has reported we have a decade left to help turn back the clock on preventing even larger scale climate disasters and rewilding of endangered species like the elephant and wolf can help promote healthier ecosystems which results in a healthier planet for you and me.
