An isolated island, blue sky, white clouds, blue ocean, beach and chirping seabirds...
The sea waves were petting the beach. Numerous finger-nail sized sea crabs were climbing out of the dense thumb-sized caves and rushed towards the sea waves at the fastest speed.
As for these sea crabs, the distance from the caves to the sea waves was the first survival test in their lives. If they could reach the sea waves after climbing over dozens of meters, they would survive themselves; if not, they would die.
When the tide came in, these tiny sea crabs would hurriedly climb out of their caves and rushed towards the ocean and the sea waves with snow-white ripples.
A lot of red-mouth seamews were chirping out of excitement and peaking those tiny sea crabs on the beach. As for these red-mouth seamews, these tiny sea crabs were their most bumper food.
Many tiny sea crabs even didn't touch a drop of seawater from their birth to death.
