0 the long supporting piece of a ship’s frame that lies lengthwise along the bottom -- lunas
Several prominent transverse wrinkles occur on the lower part of the cushion but there is no distinct keel.
Pieces of the false keel floated to the surface, but the ship was quickly refloated and found not to be leaking.
Her bow and keel were extra solid and large, to make her capable of penetrating the ice and reaching the whaling and sealing grounds.
The manner in which this was done was so approachable and friendly that it immediately put a quivering wreck on a more even keel.
Type of teeth: 0, teeth of cidaroid type; 1, grooved teeth; 2, keeled teeth; 3, teeth diamond-shaped in cross-section. 37.
The carapace has a roughly rounded outline and lacks midline or lateral keels.
It joins with the posterior keels of the cusp at an angle of about 45 degrees.
That said, might the effect of our folly in this last regard be righted by the keel of evolutionary fortune?
