Flatworms

The phylum Platyhelminthes (aka flatworms) are rather primitive invertebrates that can be either parasitic or non-parasitic depending upon the species. They have no body cavity, no circulatory organs and no respiratory organs. Questions about flatworms can be asked and answered here.

What is the name of the foil fencing move where the fencer does a jump in place before executing a lunge?

Balestra. It is not really a jump in place, for the body should cover some forward distance, even more than the lunge that follows. When the balestra is executed correctly, the body does not hop up in the air(wasted movement) but springs forward in a way that looks like a regular lunge to the opponent. But instead of the trailing leg staying back, it is immediately brought up together with the lead foot. If the opponent has evaded this first attack, he might not be ready for the lunge that immediately follows.

Is asexual reproduction advantageous to a free living flatworm?

Yes, asexual reproduction is advantageous to free-living flatworms as it allows for rapid population growth in stable environments without the need for a mate. This method, often through fragmentation or regeneration, enables flatworms to quickly exploit available resources and adapt to favorable conditions. Additionally, asexual reproduction ensures the survival of successful genetic traits within a population, which can be beneficial in consistent habitats. However, it may limit genetic diversity compared to sexual reproduction.
