👉 Trance fluid, also known as thalassone or thalassone fluid, is a complex mixture of substances found in the cerebrospinal fluid (CSF) of certain marine animals, particularly those that exhibit trance-like states or are in a state of deep relaxation underwater. This fluid contains high concentrations of potassium, sodium, and magnesium, along with various organic compounds, including amino acids, lipids, and proteins. The exact composition varies among species, but it generally helps maintain the animal's neurological function and homeostasis during prolonged submersion or unconsciousness. The presence of trance fluid is believed to play a crucial role in the animal's ability to remain calm and unresponsive to external stimuli, facilitating behaviors such as swimming in a relaxed state or participating in social interactions without fear.
