Seahorses are captured by the millions in China due to being used in Chinese medicine. They're also used for commercial use such as pendants and key chains. They also fall victims to fishing nets. Because of this they're facing extinction :( Want to help? google petitions to save them and support Ocean conservation organizations, like Oceana :)
"This is the largest crab ever caught and his name is crabzilla. Crabzilla is a 10 foot Japanese spider crab that was captured in Great Britian and currently still resides there at the National Sea Life Center in Birmingham."
