Matrifagia en arañas: cuando las crías devoran a su madre para sobrevivir

Ajouté : 2026-05-28

[00:00:00]Prepare to swallow saliva. In several spiders, especially those of the genus Stegodifus and also in Amaurobius Ferox, motherhood culminates in matrifagy because the female stops hunting, dissolves her own organs to turn them into a mush that she regurgitates for days to her young. And when these undergo their first molt, their already softened cuticle and reprogrammed physiology make it easier for them to pounce on it and devour it completely. An extreme sacrifice that in social species with communal webs boosts the survival of the litter and turns the mother's body into the last ration of parental care that is as radical as it is effective. Yeah.
