A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits.Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
So individuals of the same species will have differences to other individuals of the same species due to what habitat they grow in. [19] Many species have different morphologies for different wave disturbance regimes [18] but giant kelp Macrocystis integrifolia has been found to have plasticity allowing for 4 distinct types of blade morphology ...
The banana plant is the largest herbaceous flowering plant. [2] All the above-ground parts of a banana plant grow from a structure called a corm. [3] Plants are normally tall and fairly sturdy with a treelike appearance, but what appears to be a trunk is actually a pseudostem composed of multiple leaf-stalks .
Earthworm head. Depending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide, but the typical Lumbricus terrestris grows to about 360 mm (14 in) long. [9]
Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini.

Coconut palm leaves. Cocos nucifera is a large palm, growing up to 30 metres (100 feet) tall, with pinnate leaves 4–6 m (13–20 ft) long, and pinnae 60–90 centimetres (2–3 ft) long; old leaves break away cleanly, leaving the trunk smooth. [6]
The onion plant (Allium cepa), also known as the bulb onion [6] or common onion, [3]: 9–10 is the most widely cultivated species of the genus Allium. [ 7 ] [ 8 ] It was first officially described by Carl Linnaeus in his 1753 work Species Plantarum . [ 9 ]
This would demonstrate the possibility of such an event. Unicellular species can relatively easily acquire mutations that make them attach to each other—the first step towards multicellularity. Multiple normally unicellular species have been evolved to exhibit such early steps: yeast are long known to exhibit flocculation.
