The very bottom of a ship is where you find the keel. The keel runs the full length of the ship along its centerline and is the backbone of the hull. From the keel all the frames run out and up. the hull is attached to the frames. Picture the keel as the backbone and the frames as the ribs. The hull is the watertight skin that allows the ship to float. Within the hull are compartments (rooms) and at the top of the hull is the main deck. The superstructure is built upon the main deck.
The lowermost part of a ship - the part of the ship that is submerged under water - is called the hull.
the bottom of a ship is called the Keel.
A keel
The tail fin is called the caudal fin and the fin near the rear on the bottom side is called the anal fin.
The dorsal fin, and it's used to stabilize the dolphin while it's swimming.
Look at the fish's bottom side. If the "anal fin" is fan shaped the fish is a female, if the fin is thin and pointed like a nozzle then the fish is a male. In the male this fin is called a 'gonopodium'
The fin on the top/back of all fish is called the "Dorsal Fin."
The bridge
The fin on the back of an orca is called the dorsal fin.
It's called the hull (pronounced hul). It's the lowermost part of a ship - the part of the ship that is submerged under water. The "line" along the center of the bottom of the hull of the ship is the keel of the ship. It's laid down first when the ship is built, and is a structural component. It could be looked at as the "backbone" of the ship.
It is on the bottom
The tail fin acts as a rudder on a ship would.Turning the fish in whichever direction it wants to go in.
It's the fin at the rear of a ship used for directing the ship It is a large 'flap' that is used to steer the ship.
