Biology
The nautilus is a uniquely designed creature that was the product of a special creation. The nautilus is classified a living fossil, a marine organism (cephalopod mollusk) believed by evolutionist scientists to have fossils dating up to 500 million years ago. These fossils have not changed in appearance during this supposed time, giving evidence for the creation model. How can a living organism not change appearance in 500 million years unless this time frame is invalid and the real time frame is 6,000 years?
The ancient Greeks viewed the chambered nautilus shell as a symbol of perfection and this shell can be described mathematically as a logarithmic spiral. Nautiluses can range in diameter from 6 to 10 inches and have up to 90 sticky arms that are used to grab things, along with tiny cilia hair near the tips. The nautilus shell looks like a snail shell but is divided into chambers and the animal only occupies the largest, outermost chamber. The chambers get progressively larger from inside to outside.
The nautilus has a buoyancy-control mechanism that operates like a submarine and allows the nautilus to move in the water up and down. The nautilus shell is made up of a series of chambers connected by a long tube called the siphuncle and each chamber is filled with gas and seawater. As a nautilus grows more chambers are added to the body, starting with four chambers for a newborn to up to 30 chambers for an adult. As a new, outer chamber is grown, the nautilus moves into the new chamber and secretes a wall called a septum separating the old chamber from the new one.
The design of the nautilus allows the nautilus to descend or ascend by controlling the amount of water in the chambers and the ratio of liquid to gas. The siphuncle allows the nautilus to control the amount of water in the chambers. The movement of water into and out of the chambers is caused by osmosis, which is driven by changes in the concentration of ions within the chamber fluid.
More gas in the chamber will allow density to decrease while its buoyancy increases, enabling it to float upward in the water column. When the opposite occurs, the nautilus descends downward.
Nautiluses also use jet propulsion to move by spraying water through a tube in its body. As seawater pumps through the living chamber, the nautilus expels water by pulling its body into the chamber, thereby creating jet propulsion to thrust itself backwards and to make turns.
At neutral buoyancy, the nautilus can float or suspend itself in the waters when its body density matches the surrounding water.
The nautilus moves up and down the water column to look for food and avoid predators. The hard shell of the nautilus can withstand the extreme pressures of the deep ocean, but sometimes a nautilus will venture into higher pressure areas where the shell will break apart.
The movement system of the nautilus including the buoyancy control and the jet propulsion make the nautilus a complex organism and not a primitive one.
Some nautiluses protect themselves with slime on their bodies, making its slippery to predators trying to grab them.
Complex organisms like the nautilus emerged suddenly in the fossil record in the Cambrian period, giving evidence of a short time frame of 6,000 years and not millions or billions of years.
