Geelikujulised

Geelikujulised is a Finnish term that translates to "gel-shaped" or "gelatinous" and is used to describe a group of organisms with a soft, jelly-like consistency. This description is not a formal scientific classification but rather a common way to refer to various creatures exhibiting this characteristic.

The most common examples of geelikujulised include jellyfish. These marine invertebrates belong to the phylum Cnidaria and are renowned for their translucent, bell-shaped bodies composed mostly of water. Their movement is primarily passive, relying on ocean currents, though some possess the ability to pulsate their bells for propulsion. Other gelatinous marine animals, such as comb jellies (ctenophores), might also be informally grouped under this term due to their similar texture.

Beyond marine life, the term can sometimes be applied to certain larval stages of terrestrial organisms or even some fungi that exhibit a soft, gelatinous form. However, its primary association remains with marine invertebrates known for their jelly-like bodies. The defining feature is the lack of a rigid internal or external skeleton, resulting in a pliable and often delicate structure.
