Crabs invade Cuba's Bay of Pigs

With the spring rains... come the crabs in Cuba.

It's the march to the infamous Bay of Pigs, undertaken by millions of crabs every year.

Jorge Luis Jimenez of the Ministry of Science, Technology and Environment says the crustaceans are determined to reach the water, where they dump their eggs into the sea.
