This closeup dorsal view of the head (the animal is facing to the left) shows the supraorbital spines. Lebbeus groenlandicus has one supraorbital spine between the eye and the rostrum.
-
This closer view of the carapace and rostrum shows how deep the rostrum is and the large mid-dorsal teeth. A frozen individual.

Lebbeus groenlandicus sometimes assumes this cataleptic posture when disturbed, but seems less prone to do so than is Paracrangon echinata. Photo by Dave Cowles, July 2000

Lebbeus groenlandicus from 100 m depth in San Juan Channel. Length about 2.4 cm. (Photo by: Dave Cowles, July 2002)

This photo of a live individual also shows the banded telson, plus the red color of the sixth abdominal segment.
-
Heptacarpus sitchensis has a well-developed, toothed rostrum. None of the teeth are hinged (movable). This species' tissue is normally nearly clear. As with many shrimp, the whitish tinge appearing in the tissue here only appears when the animal is metabolically compromised and dead or nearing death. Live shrimp run so fast and so constantly that it is almost impossible to get clear photos of small body parts.
