A few interesting facts about our fishy freinds

The world's most Poisonous fish
The fish with the deadliest venom is the Stonefish, found in tropical regions, particularly around Australia. Although not aggressive or large, Stonefish are so well camouflaged they are virtually impossible to see. The fish has venomous spines on its dorsal (top) fin which are used as a defence only, most stings happen when the fish is trod on. The venom causes severe pain, shock, paralysis, and can be fatal if not treated within a few hours.
The most poisonous fish to eat is the pufferfish, which contains a fatal poison called tetradotoxin in several of its organs. The fish is considered a delicacy in Japan and must be specially prepared by trained chefs to remove the poisonous parts. Around 100 people a year die from eating pufferfish.

The world's oldest fish
The normal lifespan of a fish varies between species and can be as little as a few months for some species. Whilst it is not easy to say how old fish can get in the wild it is more than likely a few are over 100 years old. The oldest fish in captivity is an Australian Lungfish called 'Granddad' which arrived fully mature at the Shedd aquarium in Chicago and has been there for over 80 years. Goldfish are known to live for several decades, the world's oldest goldfish, "Goldie", died in 2005 at the age of 45.

The world's largest fish
Whale sharks are the current owner of this title, with verified specimens up to 13.6m (45ft) and weighing 22 tons. Larger whale sharks have been reported, some close to 60 feet, but none have been accurately documented. Whale sharks also lay the largest eggs of any animal, with eggs measuring up to a whopping fourteen inches long.

The world's fastest fish
The Sailfish is the fastest recorded fish with speeds of up to 110 kilometres per hour (68 mph), not bad for a fish that can grow to a huge 3.5 metres in length.
