birgus latro (linnaeus, 1766) The huge size coconut crab, hard shell, accompanied by two sturdy and giant claws, it looks like they look fierce and rude, so in Taiwan, people call it "Mountain Pa"; and because it is head and The lines are very close to the chest gossip pattern, also known as "gossip crab." It is also a climbing expert, especially good at climbing coconut trees straight, and it can be cut open with a strong double claws hard coconut shell, and then enjoy the sweet coconut inside (pictured). So it has a common name in the international arena - "coconut crab (coconut crab)". Because it looks too mighty, and some people just call it called "robber crab (robber crab)". In addition to preying on the chelipeds with one small look outside, the body is symmetrical on both sides, so big and strong individual, is often mistaken for crabs, hermit crabs, but it is genuine, but a family too! Because there is no lodging at bondage inside the body growth of snails, adult crab's appearance will be more substantial in weight had the largest foreign weighing seven kilograms or more, nearly half meters in length record can be said that the largest land type of arthropod. Coconut crab is derived from marine animals, and the other had it in the sea of life, and later moved to land animals, must face the problem of respiration and moisture loss. It's gill cavity wall has many blood vessels are arising, can help breathing; have a qualitative case; and habitat in high humidity, with the covert and the sun can be obscured hole gap, soft soil in order to facilitate their burrowing, hibernation or molt, as well as adequate food areas, so long-term habitat for life on land, to the breeding season before returning to sea to lay eggs. Slow the growth of the coconut crab, every individual will grow a number of molt, usually molt in the fall and winter seasons. Crab molt each year about 2 or 3 times, with greater individual length, the more reduced the number of molting, the frequency of crab molt only once a year up to it. Estimated that this slow growth rate, coconut crabs may take more than 40 years to reach 400 kg of body size. As the name suggests, coconut crabs will eat coconut, coconut meat is that it's the best doped material, it is very strong due to double claws, they are able to easily climb the high-cut coconut trees and scuttling the shell and eat the coconut meat. However, coconut meat is not its only food, it is very mixed diet, eat almost any organic matter, when it is hungry, whether it is the fruit of plant leaves, corruption, animal carcasses, and even less than their own kind, eat it, really "bulimia without disgust," so got a "robber crab" of the alias. Strange Interestingly, the coconut crab is the marine animals, but because it is long with many gill cavity wall plexus blood vessels, can help breathing, so it can live in the land a long life, but do not always live in the ocean, only to the breeding season before returning to the ocean to lay eggs. It is born of the growth and development of larvae mature in the ocean after they climbed the bank to live. This crab is widely distributed in the tropical Pacific and Indian Ocean regions. According to records, including Christmas Island in the Indian Ocean as well as Malaysia, Indonesia, the Philippines, Australia and the South China Sea and Taiwan Province are distributed. Coconut crab taste delicious, abdominal fat and more nutritious, especially in its eight feet, taste like lobster tail, combined with another unique coconut flavor. Food law, whether in the steaming, stewing, and soup are very tasty and delicious taste, etc.; and distilled water, eggs, crab cream taste good; if angelica, red dates, coupled with round stew meat is viewed as a supplement to share. Southern Taiwan area, coconut crab is also regarded as nutritious natural game, such as the abdomen where the cream yellow rice wine transferred to eat, more sophisticated product that is strong, so in addition to coconut crabs by biologists for the study, but in recent years boarded the humble, to become valuable and people favor seafood dishes, and great value for development.
