the entire ecosystem will colapse and they will all die
No, they are called teats. The milk sack is called the udder. Otters, on the other hand, are water loving animals.
Yes, according to a study done in California. Otters eat migratory water fowl. Therefore, when the ducks migrate through otter territory, they may become otter food.
Some common insects found in water gardens include dragonflies, water striders, water boatmen, and mosquitoes. These insects play important roles in the ecosystem, such as pollination, predation of pests, and nutrient cycling. It's important to create a balanced environment in your water garden to support the presence of beneficial insects while managing pest species.
Certain insects (ones with a very light weight) are able to walk on water as their weight does not break the surface tension of the water. Water has a very high surface tension, therefore easily breaking and not supporting weight above a certain limit.
Insects that are able to walk across the surface of water are called water striders. Water striders make use of the high surface tension of water together with their long, hydrophobic legs to stay above water.
the otters would have nothing to eat and the whole food chain would get ruined
There are both freshwater (river otters) and salt water otters.
In the water
Habitat destruction and water pollution are the main threats to otters.
Otters are a semi-aquatic mammal. So they don't live exclusively in water.
Some carnivores that live in freshwater environments include otters, alligator gar, pike, snapping turtles, and bull sharks. These species rely on fish, insects, crustaceans, and sometimes other animals as their primary food sources.

One effect of water's cohesion is surface tension, which allows water to form droplets and support objects that are denser than itself, such as insects walking on water.
Otters are aquatic mammals known for their streamlined bodies and webbed feet, while water rats, or water voles, are rodents that live near waterways. Otters are carnivorous predators, while water rats are herbivores. Otters are known for their playful behavior, while water rats are more elusive.
Otters are able to stay underwater for up to 8 minutes.
