Nectocaris pteryx is a species of possible cephalopod affinity, known from the early Cambrian Emu Bay Shale.
Nectocaris was a free-swimming, predatory or scavenging organism. This lifestyle is reflected in its binomial name: Nectocaris means "swimming shrimp" Two morphs are known: a small morph, about an 3 cm long, and a large morph, anatomically identical but around four times longer. Nectocaris had a flattened, kite-shaped body with a fleshy fin running along the length of each side. The small head had two stalked eyes, a single pair of tentacles, and a flexible funnel opening out to the underside of the body. The funnel often gets wider away from the head. Internally, a chamber runs along the body axis, containing a pair of gills. It is known from Canada, China and Australia, in rocks spanning some 20 million years ago.​
