Acid in Our Oceans Threatens the Beautiful Sea Butterfly

Last week we looked atsea angels , an turquoise - slug whose “ foot ” has split into wings . And what do ocean angels eat ? A type of fly sea snail sleep together as a ocean butterfly stroke . But ocean butterfly are feeling the chemical substance changeas the oceans are becoming more acidic , putting their intact aquatic ecosystem at risk .

ocean butterfliesare ocean escargot that adjudicate to leave the reason behind . Over time , their infantry morph into “ wings , ” and they use them to waft themselves through the ocean . researcher have known about sea butterfly stroke for some time . They live all over the world and there are plenty of erstwhile vignette of them ( all of which look like rejected survey for monsters in the Alien motion-picture show ) . They turn up in net , and in the fossil record .

They ’re not more commonly known for two reason . First of all , they ’re low . Most of them are only a centimetre long , with tiny , almost semitransparent shell . ( Many have lose the scale , and so were n’t always sort out with their brethren . ) Secondly , they spend their days well below the aerofoil of the ocean ( 25 measure ) , transmigrate to the top only at night .

People are taking more notice of the butterfly stroke now for an extremely sad reason . Their shells are delicate , both chemically and structurally . The calcium carbonate unthaw in acid , and without that protective shell , ocean butterflies ordinarily perish . Because they are at the bottom of the food range of mountains , their personnel casualty guggle up and impacts high - order creatures — include sea angels .

Even the types of sea butterfly stroke that do n’t have shells incline to prey on things that do have shell . So scientist arewatching these tool closelyto see if they ’re the first Antoine Domino in a blood that end in a major ecological crash .
