jellylike
Soft, wobbly, and squishy, like jelly or jello.
Jellylike means having the soft, wobbly, slightly squishy texture of jelly or gelatin. When something is jellylike, it jiggles when you touch it and feels smooth but not quite solid.
A jellyfish's body is jellylike, which helps it float and move through water. The clear, wobbly part of a raw egg is jellylike before you cook it. When you make gelatin dessert, it starts as liquid but becomes jellylike after it cools in the refrigerator.
Scientists use this word to describe many things in nature. Your brain has a jellylike consistency, protected by your skull. Some sea creatures and deep-sea organisms have jellylike bodies that help them survive in dark ocean depths. Even some fungi and bacteria form jellylike colonies.
The word captures that specific texture between liquid and solid: something that holds its shape but wobbles and jiggles. If you've ever poked a bowl of gelatin dessert and watched it shimmer and shake, you know exactly what jellylike means.
