Sealion mounted camera shows predation, mother teaching pup!

University of Adelaide and SARDI PhD candidate Nathan Angelakis has been using cameras attached to Australian sea lions (Neophoca cinerea), to capture movement and dive data to identify and map critical habitats and foraging behaviours.
The footage has shown that Australian sea lions use specialised strategies like flipping rocks, ambush predation and chasing to capture a variety of prey including fish, sharks, rays and cephalopod species. They also use these strategies throughout a diverse range of habitats like luxuriant seagrass meadows, vast sand plains, deep water sponge gardens, and complex reef ecosystems. The videos also allowed scientists to map these unexplored areas along the Great Southern Reef.
Some of the most astonishing footage collected from Nathan Angelakis’ sealion camera project is that of a mother and pup. It has been hypothesised that Australian sea lion mothers use social learning to pass on foraging
skills to their pups, a behaviour that has now been captured on video for the first time!
Angelakis describes the interactions of a mother taking her pup on an 8 hour trip to sea,
“When she was with her pup, they continuously dove together, moving across diverse habitats. We even got footage of the mother capturing a giant cuttlefish, while the pup was right next to her, suggesting that the mother is demonstrating to the pup how to locate, capture and consume prey. Getting this footage was very fortunate, as it provides crucial insight into some of the factors that drive the unique life and 18-month reproductive cycle of Australian sea lions.”

How did you manage to mount the camera on it? However, it seems to me that the light from the camera annoys the sea lion?!

8/7 NY Times ran a story. camera afixed to wet-suite type rubber size of credit card which was glued to sleeping (drugged) animal. 2 days later, when they returned to the pups, the cameras were removed. The rubber will fall off when the animal sheds its fur. The "however"? At 300 feet, if these went that low, maybe the light helped. Let me know if this helped (2 weeks later.)

@@cliffontheroad Thanks that's right!

@@cliffontheroad Thank you.

Fascinating! And I thought for sure the camera would be skimmed off when the sea lion cruised below that underwater formation. Is there a music credit?

[@GreatSouthernReef]

Thanks for watching. I know it was close! First track is 'Trolldans' by 'Strom'. 2nd is 'Skywards' by 'Aiyo. 3rd is 'Seaglass' by 'Brotin'.

❤❤❤❤❤ genial me parece fantastica la idea de que la ciencia y mostrarnos una perspectiva tan genial 😮 es asombroso ver lo que las focas pueden hacer y lograr 😊❤

[@GreatSouthernReef]

100%!

[@mycoffeeandcones]

What is the light source in the video? Is that from the camera or bioluminescence?

[@GreatSouthernReef]

There are also lights mounted on the underwater camera which is attached to the sealion!

I think that sea lion is bonnie an' mad at the camera atop her back haha
