The answer is The ability to retain moisture and burrow into the sand because they have to know how to retain moisture when there is no water during low tide. And they wo7ld not have to resist salinity.
The deserts are the regions of the lands, where there is a little precipitation and the temperature is generally too high during the day.
In the desert biome, the animals are adapted to dissipate heat to the environment, which make them remain cooler in the hot days. They have long appendages and long extremities, such as hear, which help them in constantly transferring the heat in their surrounding. Some animals lack fur, which allow them to remain cool, as the presence of fur would not allow the dissipation of the heat to the atmosphere.
The tundra biome is very cold, and the animals living there must have the tendency to trap heat to remain hot in the cold climate. All the desert animals are adapted to dissipate heat to the environment, so, they cannot trap heat, which makes them unfit survive in colder climates.

Research on brain development suggests that risky behavior in teens may be the result of incomplete development and changes that occur in the prefrontal cortex of the brain.
The prefrontal cortex is located in the frontal lobe, behind the frontal cortex. The function of this region is for executive function, an ability to differentiate good things from bad things and consequence of an activity. Incomplete development will impair those abilities, makes the teens do risky behavior.
