There have been several news reports of increased ocean water temperatures and the possible effect on marine life. Now there is some research that lake temperatures are also on the rise. NASA’s Jet Propulsion Laboratory (JPL) has found that over the last 25 years, the world’s largest lakes have been warming by as much as 4°F. Warming lakes are already experiencing water quality problems and increases in toxic algae blooms. One of the lakes being studied is Lake Tanganyika.

An aviation agreement has been signed between the two countries hoping to persuade Lufthansa to re-introduce its flights to Tanzania. Tanzania does border all three of the major African lakes. The agreement’s impact on tourism, exports and the environment will have to be seen.
The Toledo Zoo Aquarium will be closing for 2 years in order to do a $25 million renovation. Originally opened in 1939, this will be the first major renovation in its 73-year history. Although fans of the aquarium will have to go without for 2 years, the renovation will more than triple the amount of gallons on exhibit. Another plus is that other aquariums will benefit as 75% of fish are being shipped to other zoos. For instance, the Minneapolis Zoo has already received frontosas and Moody Gardens of Galveston, Texas, recently picked up 40 Yssichromis piceatus.
The smallest fish in the world is Paedocypris progenetica. Adults reach a size of only 10 mm (0.4 in). This species makes even the smallest dwarf cichlid seem large in comparison. This cyprinid is endemic to Indonesia where it’s found in water that measured a pH of 3.0! This species is so small, that until this year, it was considered the smallest vertebrate in the world. What’s the smallest cichlid in the world, you ask? That answer is up for debate. Chances are it is one of the South American dwarf cichlids or one of the Tanganyikan shell dwellers.
