Captures gruesome spectacle: Video shows 1,000 newly hatched spiders consuming their mothers and female relatives
In a groundbreaking revelation, a new five-part series from the BBC titled "Parenthood" features the cannibalistic behaviour of African social spiders (Stegodyphus dumicola) during mass migrations. Narrated by the renowned British biologist and broadcaster Sir David Attenborough, the clip presents a harsh but functional social structure that ensures the survival of the next generation.
The behaviour in question involves the cannibalization of mothers and other elder colony members when food sources are depleted. Interestingly, the spiders do not cannibalize their siblings. Instead, they turn to cannibalizing their elderly relatives, including their mothers, as a final act of survival.
A fascinating aspect of this behaviour is the mothers' intentional trembling before their deaths. Scientists believe this trembling mimics the signals that prey insects generate when caught in a web, encouraging the spiderlings to attack and consume the mother without hesitation. This trembling serves as a form of maternal sacrifice, ensuring an efficient transfer of resources from the adult spiders to the offspring.
Following the consumption of the mother, the spiderlings may continue to cannibalize other adult spiders within the colony until only the youngest generation remains. This behaviour illustrates a unique evolutionary strategy where the mothers increase the survival chances of their offspring at the cost of their own lives.
The clip, produced and directed by Jeff Wilson, shows the spiders playing a "statues" game before attacking. Wilson expressed that, while the behaviour is horrifying, it makes sense in the context of survival for the next generation.
Over 1,000 young African social spiders are seen in the video, making this a significant event in television history. The footage of this stomach-churning behaviour is the first time it has been captured on TV, according to The Guardian.
The dying spider mother's action is described as the "ultimate sacrifice" to ensure the survival of the next generation. Sir David Attenborough was both delighted and horrified by the footage, as stated by Jeff Wilson.
This brutal form of survival and resource acquisition provides vital nourishment during precarious mass migrations, enabling the new generation to sustain themselves when food is scarce. The behaviour represents an extreme form of parental care and sacrifice, promoting the colony’s future survival. After consuming the spider mother, the spiderlings continue to eat other surviving adults in the colony, leaving only the next generation.
