What is the weakest animal?

The term "weakest" can be interpreted in different ways, such as physical strength, immunity, or resistance to certain diseases. In terms of physical strength, there are many animals that are weaker than others, and it's hard to pinpoint one specific animal as the "weakest." However, some examples of small and physically weak animals include:
The Etruscan shrew, which is the smallest mammal in the world, weighing less than a penny.

Smallest mammal in the world by weight at 1.8grams on average. For perspective a paper clip is 1 gram

Today’s animal is the Fairyfly, a wasp that only grows to be around 0.5mm to 1mm long in their lifetime. With a size like that, who knows how many YOU’VE swallowed throughout your life? pic.twitter.com/RMrKqBzbfp
Also, it's worth noting that physical weakness is not always a disadvantage, as many animals have developed unique adaptations and strategies to survive in their environments.
It's also worth noting that the term "weakest" is subjective and can be interpreted in many ways, as every living being is unique and has its own way of adapting to the environment. Different animals have different strengths and weaknesses, and it's important to remember that every species has a role in the ecosystem.
