Leatherback Sea Turtle

Leatherback Sea Turtle

Dermochelys coriacea

Size: to 70" and 1200 lbs.

Habitat: oceanic

Notes: The largest sea turtle in the world, and also the most likely to be seen in our cold waters, since Leatherbacks are at least partially warm-blooded! As implied by the name, they have a leathery flexible covering, rather than the bony hard shell of all other sea turtles - a unique feature that has caused them to be placed in a family of their own, apart from all other sea turtles. Leatherbacks feed on jellyfish.

This one appears to have a propeller wound on its side.
It looks like it has been dead for a while.

Alpha-Numeric Signal Flags

In this modern age of radio, these signal flags are a quaint anachronism that is no longer used, although they were once very important in ship-to-shore and ship-to-ship communications. Each flag stands for both a letter value and a shorthand message. The letters are expressed here in the modern international phonetic alphabet, in which A-B-C would be spoken Alpha-Bravo-Charlie (see below).
