There's a about 75% chance that beetle couple will produce three successive offspring with black exoskeletons.
Some animal species' bodies are supported and shielded by hard coverings called exoskeletons. Exoskeleton literally translates to "outside skeleton." Animals without backbones known as invertebrates frequently have exoskeletons. Animals with exoskeletons most commonly include insects. Chitin is a material that serves as the exoskeleton of insects. Chitin is also a structural component of the exoskeletons of similar species such as scorpions, ticks, mites, spiders, lobsters, shrimp, and lobsters. Exoskeletons are rigid and hard, yet they also have joints or bending parts. Animals are able to move easily thanks to these joints. Land animals have spiracles, which are tiny breathing pores in their exoskeletons.
