世界上岁数最大的老鼠——太平洋袖珍鼠帕特

A tiny mouse at the San Diego Zoo has set a new world record for the oldest known living mouse. The mouse, named Pat, turned nine years and 209 days old when breaking the record . Pat is a Pacific pocket mouse,
which is the smallest kind of mouse in North America. He weighs about as much as three pennies.
Pacific pocket mice are endangered. They live in Southern California, usually within 3.2 kilometers of the

speed more efficiently. The team also plans to give joints and thicker muscle tissues to the bipedal robot to enable more complex and powerful movements. But before up-grading the robot with more biological components, the team will have to integrate a nutrient supply system to sustain the living tissues and device structures that allow the robot to operate in the air.

sea. They used to be found all along the coast, from Los Angeles down to the US border with Mexico.
The mice are a vital part of the environment because they help spread the seeds of the plants that grow naturally in this sandy area. Their digging underground also helps the plants grow.
But starting in the early 1930s, humans began taking up more and more of the area where the mice normally lived. Pacific pocket mice began disappearing. By the 1970s, scientists believed that the Pacific pocket mouse had become extinct. But in 1994, scientists found a small group of Pacific pocket mice in Orange County, California. Later, they were able to find two other small groups of the mice. But these groups were a long way away from each other, and were often separated by things like roads and buildings.
Starting in 2012, the San Diego Zoo Wildlife Alliance (SDZWA) began working to help the mice by raising them in captivity. Animals raised in captivity face fewer threats and often live longer. Pat, whose birthday is July 14, 2013, was born in the first year of that program.
In 2016, the SDZWA and several other groups helped get a group of Pacific pocket mice started in a protected area called Laguna Coast Wilderness Park. In 2017, the numbers of mice in the park began growing without any help from humans. In 2022, 31 litters (groups of baby mice) were born at the zoo, and there were 117 pups in all. SDZWA says that many of these mice will be released into the wild. But Pat won’t be joining them. Now he’s extremely old for a mouse.
