Crayfish are invertebrates which means they don't have a backbone. They are also arthropods, which means that they have a protective exoskeleton on the outside of their body. Other arthropods include insects, spiders, and centipedes. Crayfish continually shed their exoskeleton and regrow a new one. During this transition is when they are most vulnerable to predators because they aren't protected by their outer shell.
Crayfish are found all over the world in many different freshwater environments, such as rivers, creeks, springs, and swamps. But this doesn't necessarily mean that you will be able to find them. They are somewhat cryptic because they dig out homes for themselves under rocks and blend in well with their environment. Crayfish will ardently defend this dwelling against intruders using their strong front claws
The difference between diploid and haploid cells a duplicated chromosome consists of two sets of chromosomes.
The diploid cells consists of two sets of chromosomes whereas the haploid cells consists of one set of chromosomes. The haploid cells are formed by the process of meiosis and the diploid cell formed by the process of mitosis.
In the higher organism, such as human the gametes are haploid and beside their all cells are diploid. The diploid cell when reproduce or increase their number through mitosis they form identical copy of its chromosomes.
