This form includes verbal or speech developmental apraxia, perhaps the most common form of the disorder. Constructional apraxia affects the person's ability to draw or copy simple diagrams or to construct simple figures. Oculomotor apraxia is a condition in which patients find it difficult to move their eyes.
Medium ones about the size of a golf ball may molt every four to six months and stay buried for about one to three months. The smaller hermit crabs may molt as often every month or even every few weeks for the tiniest ones, and may stay buried to do it for only a couple of weeks or months.
The comfort zone for hermit crabs is 70 to 75 degrees Fahrenheit. That is when they are most active and healthy. If the temperature drops to between 50 and 60 degrees Fahrenheit, dormancy and hibernation will occur. A long hibernation may permanently affect the hermit crab.
