Platyhelminthes is the phyla of the marine flatworm.
Spruce trees belong to the phylum Coniferophyta, which is part of the larger division of gymnosperms. This phylum includes various tree species that produce cones and have needle-like leaves, adapting them to various climates. Spruce trees are specifically classified under the genus Picea within this phylum.
Are you asking: "how long does a flatworm live?"If so, this is not an answerable question--there are too many types of flatworms to make a generalization.I personally know of one type of flatworm which can re-generate--cut off any part of it's body, and that part will re-generate. As long as the head remains attached, the re-generation can take place.I did a science project using freshwater planarians, where I explored this phenomenon.
