Son holoplanct\u00f3nicos, es decir, que forman parte del plancton toda su vida. Demuestran una fuerte adaptaci\u00f3n a la vida pel\u00e1gica, en forma de una concha aragon\u00edtica (forma cristalina del carbonato de calcio) lenticular, aplanada lateralmente, cuya superficie se agranda a\u00fan m\u00e1s por la presencia de una quilla ancha, muy delgada y fr\u00e1gil, de doble pared. El \u00e1pice est\u00e1 en el lado derecho de la concha, el ombligo en el izquierdo.  Su tama\u00f1o corporal es microsc\u00f3pico, con un di\u00e1metro de concha inferior a 1 cm, y el pie ha evolucionado hasta convertirse en una aleta natatoria musculosa, que se extiende anteriormente bajo la cabeza; nadan con la parte ventral hacia arriba mediante la ondulaci\u00f3n de esta aleta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La concha est\u00e1 enrollada dextralmente (en el sentido de las agujas del reloj). La delgada quilla de doble pared se extiende desde el \u00faltimo verticilo. El \u00e1pice de la concha se encuentra a la derecha y el ombligo a la izquierda. La concha y la quilla pueden ser calc\u00e1reas (g\u00e9nero <em>Atlanta<\/em>) o estar compuestas exclusivamente de conquiolina (g\u00e9nero <em>Oxygyrus<\/em>), o la concha puede ser calc\u00e1rea y su quilla estar compuesta de conquiolina (g\u00e9nero <em>Protatlanta<\/em>). Los caracoles de esta familia pueden retraerse en su concha y cerrarla con un op\u00e9rculo cartilaginoso y flexible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Actualmente se conocen 24 especies, de las cuales 21 pertenecen al g\u00e9nero <em>Atlanta<\/em>. En el caso de <em>Oxygirus<\/em>, este es monoespec\u00edfico, teniendo como \u00fanica especie a <em>Oxygyrus inflatus<\/em> Benson, 1835, presente en Chile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong><strong>Atlantidae<\/strong>&nbsp;de Chile<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En Chile hay ocho especies de atl\u00e1ntidos, distribuidas en los g\u00e9neros <em>Atlanta <\/em>(7 spp.) y <em>Oxygyrus <\/em>(1 sp.)
