This hermit crabs omit a chirping sound when threatened!
The Land hermit crab is so well adapted to life out of water that it will drown if kept underwater! It has special gill chambers that act as lungs. These chambers are large and holds water to keep the gill filaments wet. The hermit crab only needs to occasionally dip in either rainwater or the sea to keep the chambers wet. Females, however, must go to the edge of the sea to release their eggs into the sea. These hatch into planktonic larvae. When the larvae develops into a small hermit crab, it finds an empty shell then heads landward.
Hermit crabs change their shells regularly but only when they find a larger and newer shell to feel safe in! Ref: https://en.wikipedia.org/wiki/Coenobita_rugosus
