This a close-up of the chin of a humpback whale. Conchoderma auritum are the elongate creatures that don't look like barnacles (but are). They actually grow on the other barnacle, Coronula diadema.

Conchoderma virgatum and Conchoderma auritum in southern elephant seal surface

Pulled off a boat hull. These pelagic barnacles commonly attach to ships and whales.
-
Two large sessile barnacles washed up on the beach. There are very few barnacles of any kind in the beach drift on Nevis.
-
Barnacle adhered to the feathers of a dead Magellanic penguin, during the mass stranding of penguins in Brazil in 2008.

Maybe Austromegabalanus nigrescens? Not common but I found a few more @nzshells :) Glove marks 10mm apart

Not sure what one this is. About 10mm wide.
-
Not sure which one this is. Living in the mid intertidal zone. Would you be able to help @nzshells? :)

On a large tree trunk washed up on Muriwai Beach. The largest barnacle heads are 52mm long, and their stalks up to 500mm long x 20mm wide.

Barnacle. ID ?? Guess at Balanus genus. Unusually large, flat species which I'm struggling to identify. Almost the size of an adult Cellana radians limpet but even lower profile with quite small parieties compared to the diameter of the shell structure. Initially on turning the cobble it looked to be a flat worm until given a prod and realisation it was a fixed hard encrustation dawned.
