Surprising Design of the Cuttlebone

The cuttlefish is a critter found in marine environments deep and shallow, warm and cold. Do not attempt to cuddle a cuttlefish. They have tentacles, ink, and so on like their squid and octopus relatives. Believers in universal common ancestor evolution have problems with them.

They have eight appendages called arms, plus two tentacles that these predators use to grab their prey and bring into their unloving arms. Amazingly, cuttlefish are colorblind, yet can camouflage themselves like their octopus cousins. Yet they only have a lifespan of one to two years.

While the ability to camouflage themselves is problematic enough for evolutionists, there is also the cuttlebone. It is an excellent example of the Master Engineer's work. This bone has a "sweet spot" between rigidity and stiffness.

Some of the most fascinating marine animals are the cephalopods, which include squid, octopus, and cuttlefish. God has designed the cuttlefish (family Sepiidae) with a strange and important structure called the cuttlebone, a brittle, internal shell designed with gas-filled chambers that’s used for buoyancy control.

. . . The bone is not exactly robust, yet it can tolerate a great deal of damage. A recent Virginia Tech news release spotlighted a study led by mechanical engineering professor Ling Li, who heads the Laboratory for Biological and Bio-Inspired Materials.
