👉 A strand fluid is a type of polymer found in certain living organisms, particularly in marine invertebrates like jellyfish and some sea squirts. It is composed of long, flexible protein chains that can form a gel-like structure, providing the organism with essential mechanical properties such as elasticity and resilience. These fluid polymers are highly dynamic, allowing the organism to change shape and move in response to environmental stimuli. The strand fluid's unique structure enables it to maintain its integrity while also being capable of rapid deformation, which is crucial for survival in the fluid environments these organisms inhabit.
