The skeletal and digestive system of a crayfish are unlike ours.
Humans lack the enzyme required to produce vitamin C internally, unlike most animals. This is due to a genetic mutation that occurred in our ancestors millions of years ago.
Various life forms have different genetic systems, such as DNA-based genetic systems in most organisms including humans and animals, RNA-based genetic systems in some viruses, and plasmid-based genetic systems in bacteria and other microorganisms. These genetic systems contain the hereditary information necessary for growth, development, and reproduction of the organism.
The organism that is most different from humans is the bacteria.
Humans are most closely related to chimpanzees.
Humans share the most DNA with chimpanzees.
Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine). Gills: Crayfish respire underwater through gills, where humans use lungs. The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).

Yes. You have MN system of blood group in humans.
Most biologists will tell you that the rostrum is a process for protection of the eyes from predators and during fights, somewhat analogous to the bones around the eye socket in humans.

There are several hundred different species of crayfish around the world. The most common one in US seafood markets and restaurants is the red swamp crayfish, Procambarus clarkii, most of which come from Louisiana.
The skeletal system and the digestive system.
half bronze, half celestial, it can kill both humans and monsters which is unlike most swords
The dorsal side is its back, and the ventral side is its 'stomach'. The crayfish is vulnerable on its soft underbelly - the ventral side.
One problem with keeping crayfish as pets is that most crayfish can not be in the same tank. The biggest one usually becomes dominant and injures or even kills the others. Another problem is that if a crayfish and their tank are not properly taken care of it can begin to smell very bad.
