Jelly Fish Plushie GMM Igreja do Evangelho Quadrangular Regio 629 Alegrete RS. Despite their name, jellyfish aren't really a type of fish they have no backbone and they absorb oxygen from water through membranes. Because jellyfish tend to just follow the currents of the ocean, they can be found around the world in every type of ocean water. They can thrive in warm tropical water or cold Arctic water. They've been found at the bottom of the ocean and near the surface. A collection of jellyfish are called a "bloom," "smack," or "swarm." Our handknit collection comes in yellow, peach, pink, mint and light blue! Each handknit Jellyfish measures approximately 4 inches in diameter Do remember, that each hand knit item is unique and sizes may vary slightly. Hand knit with love by a mama who also plants rice in the rice terraces (take a look at the P20 bill to see what they look like).
