Why are Hermit Crab Populations Decreasing?

What is one question that students should ask when researching the decreasing population of hermit crabs?

Explanation:

Hermit crabs are known for using gastropod shells to protect their bodies and only exposing their heads. However, the population of hermit crabs has been decreasing in recent years. One of the main reasons behind this decline is suffocation and exposure to toxic paint.

Many hermit crabs are actually dying slowly from suffocation. This is because their gills require a high level of humidity in order to breathe properly. When the humidity levels drop, the hermit crabs are unable to breathe effectively, eventually leading to their death.

Another significant factor contributing to the decreasing population of hermit crabs is exposure to toxic paint. The tap water that hermit crabs are exposed to often contains harmful substances from the paint, which can dissolve their shells over time. As a result, the hermit crabs are slowly poisoned by these toxic substances, ultimately leading to their demise.

Therefore, it is crucial for students to investigate the impact of suffocation and toxic paint on hermit crab populations in order to understand and address the reasons behind their decreasing numbers.
