Please drive carefully in northern & southern hotel zones …

Endemic to Cozumel, the Blue Crabs (Cardisoma guanhumi) are a protected and threatened species.  Their name can be a bit of a misnomer, since they’re not always blue in color, and in fact, range from shade of blue to even red-hues.  Also adding to the crab confusion, is the fact that they are considered to be land crabs, however, the females lay their eggs in sea, as many as 3,000 during  their short lifespan,  where they are born and then spend the beginning of their lives in the ocean.

This time of year, usually just after rain storms, there are often mass migrations of female blue crabs crossing coastal roads in order to reach the ocean.  Outreach and educational programs are in place in order to encourage both island residents and visitors to drive with care so as not to further endanger the migrating Blue Crabs.

Areas on the island with the highest population of Blue Crabs include   the vicinity of the Cozumel Country Club, Isla de Passion and the Palancar area, which are heavily populated by wetland and mangrove areas.  For more information on Cozumel’s Blue Crabs and how you can protect them, click here.


Protejamos el cangrejo azul en peligro de extinción; conduzcan con precaución

Por favor conduzca con cuidado en las zonas hoteleras norte y sur …

El cangrejo azul (Cardisoma guanhumi) es una especie endémica a Cozumel, protegida ya que se encuentra en peligro de extinción. El nombre puede ser un tanto inapropiado ya que estos cangrejos no siempre son de color azul, y de hecho sus variados colores van desde los tonos azules hasta los rojos. Además de está confusión con los cangrejos, está el hecho de que son considerados cangrejos de tierra, sin embargo, las hembras colocan en el mar hasta 3,000 huevos durante sus cortas vidas, y es donde las crías nacen y pasan el inicio de su existencia.


Por lo general, durante esta época del año y después de las lluvias, se ven las migraciones masivas de hembras atravesando los caminos costeros para llegar al mar. Ya se han dispuesto los programas de divulgación y educación para promover tanto entre los habitantes de la Isla como entre los visitantes, que conduzcan sus vehículos con cuidado para no acrecentar el peligro de extinción a los cangrejos azules migrantes.


Las zonas de la Isla donde existe la mayor población de cangrejo azul son: en las cercanías del Cozumel Country Club, la Isla de la Pasión y Palancar, que son áreas sumamente pobladas debido a los humedales y manglares.  Para mayor información sobre el cangrejo azul de Cozumel y cómo protegerlos, entren aquí.
