Coconut crab or lobster cooked in coconut milk is one of the most delicious dish that I have tasted in Marinduque. So what what is a coconut crab? Here's what Wikipedia says:
The coconut crab, Birgus latro, is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest land-living arthropod in the world, and is probably at the upper size limit for terrestrial animals with exoskeletons in recent Earth atmosphere, with a weight of up to 4.1 kg (9.0 lb). It can grow to up to 1 metre (3 ft) in length from leg to leg. It is found on islands across the Indian Ocean and parts of the Pacific Ocean as far east as the Gambier Islands, mirroring the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar.
In the Cook Islands, the coconut crab is known as unga or kaveu, and in the Mariana Islands it is called ayuyu, and is sometimes associated with taotaomo'na because of the traditional belief that ancestral spirits can return in the form of animals such as the coconut crab
Slipper lobsters are a family of decapod crustaceans found in all warm oceans and seas. Despite their name, they are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. Slipper lobsters are instantly recognizable by their enlarged antennae, which project forward from the head as wide plates. All the species are edible, and some, such as the Moreton Bay bug and the "Balmain bug" (Ibacus peronii) are of commercial importance.
I am looking forward to eat these two delicacies in Marinduque next week.
