Kemp's ridley turtle is one of the most endangered sea turtles in the world. It is one
of only two species of sea turtles that lays eggs in large nesting groups known as
arribadas. They generally nest on beaches along Mexico's Gulf coast, with some
nesting in Texas. There were once vast numbers of this kind of turtle. In fact, in 1947, at
least 42,000 nested together on a beach in Mexico. Unfortunately, people harvested the
eggs for eating. As a result, the Kemp's ridley turtle population had greatly reduced by
the 1960s. In 1966, Mexico passed a law forbidding harvest of the eggs, but the number
of turtles continued to decline. Adult turtles also frequently got caught in fishing nets
during their ocean migrations.
By 1985, only 702 nests were counted. This was the smallest number ever recorded.
Fortunately, with awareness of the turtle's plight, measures have been taken to protect
them. Fishing nets that do not allow turtles to get trapped are now being used. In
addition, there are better laws to protect the beaches where these turtles nest. Thanks
to these measures, the species has gradually begun to thrive again.
