In Providencia, Colombia, the black crab (Gecarcinus ruricola) is facing a severe population decline, dropping from an estimated 20 million to just around 1 million due to climate change, overharvesting, and roadkill. The local community, with a population of about 5,000, has adapted to the crabs' seasonal migration, which disrupts daily life as they travel from the hills to the sea to spawn. Conservation efforts, led by biologists like Asilvina Pomare, include closing roads during the critical spawning period from April to July and conducting awareness campaigns to educate younger generations about the crabs' ecological importance. The black crab plays a vital role in the island's ecosystem, improving soil quality and serving as a food source for various species. Its cultural significance is profound, as it is featured in local cuisine and traditions, with many families depending on it for their livelihoods. Despite efforts to breed crabs in captivity, challenges remain in sustaining these initiatives economically, highlighting the urgent need for continued conservation efforts to protect this emblematic species.
