Specimen ca. 6cm. Female?

From Oman (2012): https://acsweb.ucsd.edu/~ekeen/resources/Euphausiidae_CoastalNEP_FINAL.pdf:
Gills in the specimen are clearly visible (Euphausiidae)
Photophores in abdominal segments 1-4; Round eyes; eight and seven thoracopod greatly reduced; Smooth carapace without denticles; Lappet small/non existent (Thysanoessa)

From "Marine Species Identification Portal": http://species-identification.org/species.php?species_group=euphausiids&id=85:
Triangular rostrum with big slightly narrow spherical eye; Second thoracic legs/thoracopods only slightly longer than the rest; Abdominal segments 2-3 with blunt keels; Abdominal segments 4-6 with strong dorsal spines (T. spinifera)

Natural history matches the location of the specimen captured as epibenthic, common in docks and coast (Oman 2012).

Specimen ca. 10cm. Collected next to dock at 10pm.

Specimen was identified based on webpage from Dave Cowles (2005); https://inverts.wallawalla.edu/Annelida/Nereidae/Family_Nereidae_Key.html.

Species ID given based on the shape of the paragnaths. in everted pharynx, being comb like rather than conical, and not as transversally elongated as in P. monterea; 4 tentacular cirri on the peristomium.

Specimen ca. 1cm.
Identified based on Hormiga (1994). Couldn't get apophysis on pedipalp trochanter but tuft of 10 spines in the prolateral-ventral margin of legs I complements the similarity on shape and location of sclerites in cymbium and tegulum.
