How Old is the Vampire Squid?

Published in Cephalopod Biology 2 mins read

The vampire squid's lineage, traced through the fossil record, goes back an astounding 165 million years.

Unraveling the Vampire Squid's Ancient Past

Often referred to as a "living relic," the vampire squid represents an incredibly ancient branch of cephalopod evolution. Its history spans a vast geological timescale, showcasing remarkable resilience and adaptability.

  • Evolutionary Age: The 165 million years refers to the duration its lineage has been present in the fossil record. This means that the ancestral forms from which the modern vampire squid evolved were already distinct and identifiable during the Jurassic period, evolving from an ancestor shared with what would become the octopus.
  • Deep-Sea Survival: The vampire squid is an extremophile, perfectly adapted to the challenging conditions of the deep ocean. It thrives in the dark, cold waters at depths typically ranging from 2,000 to 3,000 feet. This specialized habitat has likely contributed to its long-term survival as a species, protecting it from many of the environmental changes that have impacted other marine life over millennia.
  • Misleading Name: Despite its intimidating name and dark appearance, the vampire squid does not suck blood. Its name likely derives from its dark, cloak-like webbing and distinctive red eyes, rather than any vampiric feeding habits.

The extraordinary age of the vampire squid's lineage highlights its unique place in marine biodiversity, representing a successful and ancient lineage that has persisted for millions of years.
