Friday Squid Blogging: Sex Life of Deep-Sea Squid
There’s evidence of indiscriminate fertilization in deep-sea squid. They mate with any other squid the encounter, male or female.
This unusual behaviour, they said, may be explained by the fact the squid is boosting its chances of successfully passing on its genes in the challenging environment it lives in.
In the Royal Society paper the team writes: “In the deep, dark habitat where O. deletron lives, potential mates are few and far between.
“We suggest that same-sex mating behaviour by O. deletron is part of a reproductive strategy that maximises success by inducing males to indiscriminately and swiftly inseminate every [squid] that they encounter.”
Basically, they can’t tell males from females in the dark waters, so it just makes sense to mate with everybody.
