Banded Rudderfish

Seriola zonata

Size
to 24"

Habitat
Coastal surface waters, congregating around any floating objects

Description
Juveniles ( shown, up to 12" ) are attractively patterned with six or seven dark bars; these are lost in adults, which are also much slimmer. Schools of small Rudderfish can often be found around boats, and even around divers hanging on the anchor line. Pilotfish are similar, but larger and retain dark bars throughout life.

Portholes & Deck Lights

Portholes are used to let light and air into a ship. They are usually constructed of brass for corrosion resistance, which makes them highly desirable as collector's items. The drawing at right shows all the major parts:

The immovable backing plate, bolted to the vessel's hull, which carries the hinges for the swing plate and deadlight
The glass swing plate, which is secured shut by large butterfly nuts called 'dogs'
The deadlight, used when it is desired to black-out the vessel, as in time of war
