In 1785 a star study of the heavens produced a star map of the Milky Way Galaxy that slightly resembled an amoeba (micro biologists might disagree) [See link]
Since the Hubble telescope, no galaxy has been found, yet, that resembles an amoeba.
There is a possibility than an a irregular or a merging galaxy might resemble one, one day.
It looks like a flat disc. See related link for a picture of the Sombrero galaxy edge on.

Amoeba is animal-like because they can not do photosynthesis which other plant-like protists can do. Amoeba are protozoans. Amoeba hunt for their food. They eat bacteria, smaller protozoans and other smaller organisms.
No. Amoebas are in the Kingdom Protista, and Germs are in the Kingdom Bacteria. Basically opposite ends of the galaxy.
the amoeba is more like plants and the paramecium is more like animals
An Elliptical Galaxy

Not surprisingly the Starfish Galaxy or NGC 6240 in the constellation Ophiuchus
it looks like a cluster of stars. it kind of looks like a clould. by Eva
An irregular galaxy looks sort of like clouds in the sky. A large part of an irregular galaxy is made of clouds of dust and fine rock. The Milky Way galaxy looks like a pinwheel, and some galaxies look like near-perfect discs.
It looks like a giant oval.
It looks like a flat disc. See related link for a picture of the Sombrero galaxy edge on.
Simply Becca's it looks like a whirlpool. See related link for a pictorial.
A spiral galaxy.
It looks similar to a toy pinwheel, with concentrations of stars along curved arms that would be the vanes of the pinwheel. (see the related image link below)
The best example is amoeba. They move by using these "false feet" extending their cell into what looks like foot and then retracting it. That results in them pulling themselves forward or to the side.
