Possible evidence of paternal care in bigfin reef squid in the United Kingdom

Published 2021년 9월 7일

Tridge summary

Researchers have discovered that bigfin reef squid males exhibit uncharacteristic paternal behavior by helping females find safe locations to lay their eggs. This behavior, observed in the Red Sea and off the coast of Indonesia, challenges the norm of male squid fighting and guarding their mates to prevent other males from fertilizing the eggs. This finding, published in the journal Ecology, highlights the complexity of squid mating rituals and suggests that more research is needed to understand these behaviors in depth.

A trio of researchers, two from Universidade de Lisboa, the other from the American Museum of Natural History, has found possible evidence of paternal care in a cephalopod. In their paper published in the journal Ecology, Eduardo Sampaio, Samantha Cheng and Rui Rosa describe recording bigfin reef squid mating behavior in two vastly different areas. As part of ongoing research into squid, the researchers were recording specimens around the world. As part of their work, they captured images of bigfin reef squid mating rituals in the Red Sea and off the coast of Indonesia. The researchers found something unusual in the video—the male appeared to be helping the female find a suitable place to lay her eggs.The researchers note that typical behavior for male squid involves ...
