Image of Heptacarpus Holmes 1900

Description:

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.
