Distribution This species was described from a whalefall, a dead whale which was experimentally placed in Monterey Canyon, California at a depth of 1820 m (). It was also seen on video from an ROV at another whalefall in Santa Cruz Basin, at a depth of 1676 m.
Description Dendronotus patricki is a translucent species of Dendronotus with no surface markings and a reddish-brown hue to the body. It grows to at least 25 mm in length. There is a small amount of opaque white pigment at the tips of the dorsal appendages, velar appendages and rhinophore sheath papillae.
Habitat Dendronotus patricki was found crawling on a muddy seabed. Its stomach contents included structures thought to be nematocysts. It is possible that it feeds on burrowing cerianthid anemones as does Dendronotus iris.
