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.
Adult females must molt in order to mate but males do not. Adult males often skip a molt and keep the same shell for one or two years. Red king crabs can grow very large with the record female and male weighing 10.5 and 24 pounds, respectively. These large crabs were estimated to be 20â30 years old. The male's leg span was nearly 5 feet across.
