Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.

Explanation:

These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.

The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.

The three benefits for removing the sea walnut:

1. The population of other species will increase as sea walnut is an invasive species.

2. The balance of the marine ecosystem can be maintained.

3. Humans can be protected from the harm caused by these animals.
