MBARI (Monterey Bay Aquarium Research Institute) | Gliding through the week like this mama Gonatus squid. 🦑 @MBARIvideo | Uploaded January 2024 | Updated October 2024, 19 hours ago.
For decades, marine biologists assumed that all squids laid their eggs in clusters on the seafloor, where the eggs developed and hatched without any help from their parents. However, MBARI scientists discovered that some female deep-sea squid, like this Gonatus onyx, brood their eggs by carrying them between their arms until the young hatch and swim away. Gonatus females will have approximately 2,000 to 3,000 eggs in a sheath between their arms for as long as nine months. During this time they are unable to feed and must rely on stored fats from previous meals. This observation of the first known parental care behavior by squid was also an important discovery made possible by the use of MBARI’s remotely operated vehicles.
