It is common for creatures to be able to live in both the spray zone and low tide zone
VMariaS [17]

The littoral zone is also known as the intertidal zone is the place where the land and sea meet and is found between the low and high tide zones. This diverse marine ecosystem is witnessed along the coastlines globally. It comprises ample nutrients and oxygen and is considered home to numerous species.  

The littoral zone is further differentiated into vertical zones, like the spray zone and low tide zone. Spray zone also known as the upper littoral, and is dry in the majority of the time, but sprayed with water at the time of high tides. It gets flooded at the time of extreme high tides and storms.  

The low tide zone also is known as the lower littoral zone, is generally found under water and gets exposed when the tide becomes abnormally low. The species in this zone are not well used to extreme temperatures and long duration of dryness.  

Some of the common organisms found in both spray and low tide zones are isopods and limpets.

answer:

by having a high genetic level of melanin in your skin, you're skin is more protected from the ultra violet sun rays. Darker skinned races have more melanin present, these races originate from hot countries where sunlight is often present; the production of melanin in their skin allows them to reflect and inhibits they're skin from becoming extremely damaged. Light skinned races don't have a large amount of melanin due to they're native countries lacking sunlight. This is an evolutionary adaptation of the human race.
