Pistol Shrimp
The common name Pistol Shrimp can refer to one of the 600 species belonging to the family Alpheidae. They are also sometimes referred to as Snapping Shrimp. Most species are found in tropical and temperate saltwater, though others are able to live in colder seas, and even in freshwater caves. They feed off of fish and other crustaceans and typically live within burrows.
They are an interesting little family of Crustaceans in that they share a handful of bizarre characteristics. The first is physical: all species have one "normal" sized claw, while the second claw is much, much larger. They use these claws for what is probably their most interesting trait; their title as one of the loudest creatures in existence. Even though they are small, growing not much larger than a few inches, Pistol Shrimp are able to produce 218 decibel sounds. This is louder than a gunshot, (typically around 190 decibels) and comparable to sounds made by the 50 ton Sperm Whale. They do so by snapping their large claws closed, which creates something called a cavitation bubble. When this bubble collapses, it not only produces an incredible loud pop, but it also, very briefly, creates extremely hot temperatures, up to 4700 degrees Celsius! (that's nearly 8,500 Fahrenheit) This bubble is able to stun prey, and on a human beings feels like getting snapped hard by a rubber band.
Pistol Shrimp also have an interesting relationship with Goby fish. The two creatures share a burrow and remain in physical contact at all times. The Shrimp have terrible eyesight, but the Goby's is exceptional. If the Goby spots danger, it twitches to warn the Shrimp, and both are able to move to safety. In return, the Shrimp maintains the den that they share. This relationship exists even with captive shrimp and fish.
The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a
For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!
Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km) from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills.
