The longest goldfish to date measured 18.7 inches. The fish, which belonged to a Dutch lady, was never weighed, so his mass remains unclear. However, a goldfish caught in Michigan measured 15 inches and weighed 3 lbs, so itâs safe to assume that Dutch behemoth weighed in excess of 3 lbs.

Return to Platypus Page. The platypus is the only Australian mammal known to be venomous. Adult males have a pointed spur (about 15 millimetres long) located just above the heel of each hind leg, which can be used to inject poison produced by a gland in the thigh (the crural gland).latypus venom is not considered to be life-threatening to a healthy human. However, spurring is painful-in part, because platypus spurs are sharp and can be driven in with great force. As well, platypus poison triggers severe pain in the affected limb and can result in quite spectacular localised swelling.
