||
|
Harmothoe magellanica |

mostly bidentate with stout secondary tooth, some unidentate |
margin with few digitiform papillae; microtubercles reduced to anterior patch or covering almost entire elytral surface |
antennae and cirri papillaed; body brown dorsally |
|
Harmothoe sp. 1 |
ventrally |
dorsolateral, on widest part of prostomium |
mostly bidentate with very slender secondary tooth (often broken off), some unidentate |
outer lateral margin with dense, elongated papillae; microtubercles covering most of the elytral surface; some tubercules enlarged near posterior margin, distally covered by small papillae |
Elytra often present (not easily lost) |
|
Eucranta mollis |
ventrally |
anteroventral, near anterior margin of prostomium |
with slender forcep-like tips and with stout bidentate tips |
margin and surface smooth, except for patch of conical microtubercles near anterior margin |
antennae and cirri smooth; body with reddish-brown horizontal stripes dorsally |
|
Austrolaenilla cf. antarctica |
ventrally |
lateral, near anterior margin of prostomium |
with unidentate, hirsute tip; upper/middle and lower groups similar |
margin almost smooth; entire surface densely covered with conical microtubercles |
body large (around 40mm), purple dorsally; nephridial papillae from chaetiger 5 |
|
Austrolaenilla sp. 1 |

all elytra missing |
body colour yellow |

Polynoidae juveniles indet. |
many juvenile polynoids of (likely) several species were also encountered, generic placement of these is not reliable; record only |
