The heart is at the top of the back, just behind the head, and the average heart rate is about 180 bpm under normal conditions. Daphnia spp., like many animals, are prone to alcohol intoxication, and make excellent subjects for studying the effects of the depressant on the nervous system due to the translucent exoskeleton and the visibly ...
Holiday heart syndrome, also known as alcohol-induced atrial arrhythmias, is a syndrome defined by an irregular heartbeat and palpitations [1] associated with high levels of ethanol consumption. [2] Holiday heart syndrome was discovered in 1978 when Philip Ettinger discovered the connection between arrhythmia and alcohol consumption. [ 3 ]

Daphnia have a compound eye, and they are known to have an optomotor response. [12] D. pulicaria generally have a body length less than 3mm. [ 3 ] Because of the clear carapace of Daphnia , it is possible to see the heart and digestive tract, which often appears to be green due to the consumption of algae. [ 11 ]

Per the American Heart Association (AHA), alcohol is one of the leading causes of dilated cardiomyopathy. [2] However, multiple longitudinal studies have shown a paradoxical lowering of dilated cardiomyopathy with modest-to-moderate alcohol consumption. [2] ACM is a type of heart disease that occurs due to chronic alcohol consumption.
Like all Daphnia species, D. longispina is a filter feeder, collecting particles of about 2 to 40 μm suspended in the water. [5] The main food are green algae. At 20 °C maturity is reached within about 6 to 12 days, followed by a period of regular reproduction in about 3-4 day intervals.
