Blood Worm

Blood Worm

Glycera spp
Nereis spp.(shown)

Size: to 15", generally much smaller

Worms like this can be found anywhere from tidal flats to deep depths, burrowed in the sediment or hiding in crevices.

These segmented worms have four sharp teeth and can give you a good bite if you're not careful. They can also swim, although not very well. The "legs" are called parapodia and are actually gills. The best place to see a blood worm is at the bait shop. Also known as Clam Worms.

A steam-powered winch on a schooner barge. Note the various drums for drawing up anchor chain, towing hawsers, etc, and the anchor chains themselves going down through the deck into the chain locker below.

Prior to steam power, the only force available on a sailing ship to perform all the necessary work was the men on board. For some tasks, such as raising the anchor, it might be necessary to yoke the entire crew to a multi-deck manual capstan. On the largest vessels, even with every available man, this might take several hours to complete. With the advent of steam power, a "donkey engine" and a single engineer could do the work of many men, in less time, and these were soon installed in almost all vessels.
