| With its finely setose appendages, G. tigrinus may be capable of suspension-feeding, as has been reported for other nontubicolous amphipods. |
|
| A setose lobster has distinct hairs on the swimmerets under its tails, indicating breeding condition. |
|
| The antennae are setose, the legs slender, with cerci that are usually rather short. |
|
| From a subset of each group the Dufour's gland and later setose membrane were dissected by removing the sting apparatus with blunt forceps. |
|
| The uropods are usually setose and paddle-shaped in swimming taxa and form a broad tail fan with the telson for rapid propulsion. |
|
| Palpi dark red-brown to black, 2-segmented, white setose, largely hidden within stomal area. |
|
| Femora dark red-brown, metathoracic femora with yellow-brown proximal and distal ends, mixed dark red-brown and pale yellowish setose. |
|
| Scutellum dark red-brown, largely apruinose except for small anteromedial area, fine white setose. |
|
| Scutellum dark red-brown, largely apruinose except for two dull gold pruinose areas anteriorly, fine pale yellow setose. |
|
| Although the larvae of the fifth stage have somewhat natatory setose on their pleopods, they appear not to be completely functional. |
