Incredible photographs of a sea lion almost being swallowed whole by a humpback whale have been captured in what is thought to be a world first.
The sea lion — estimated to weigh around 180kg — is seen being engulfed* by the whale’s jaws off Monterey Bay, California, US.
Humpbacks hunt with their huge mouths agape*, swallowing fish as they go and filtering almost 2000 litres of water in a single mouthful.
Three of the whales were feeding alongside around 200 sea lions when the unlucky creature got caught in the wrong place at the wrong time.
Luckily though, a humpback’s throat is relatively small — about as wide as a watermelon — so the sea lion survived the encounter.
Wildlife photographer Chase Dekker, 27, said that normally the agile* sea lions are able to avoid the whales as they compete for food.
“Typically what happens is the sea lions are at the surface as they don’t dive as long and as deep, and when the whales start racing up to the surface to lunge and catch the fish, the sea lions can see, hear, and sense them coming and jump out of the way,” he said.
“Occasionally, you’ll see a sea lion riding the wake* of a lunging* whale or maybe bumping the side, but nothing like this.”
He took the photos on July 22 and said he believes it is the first time a humpback getting a mouthful of sea lion has been caught on camera.
“Typically when the whales lunge feed at the surface, they close their mouth almost immediately to trap the fish as they sink back down into the sea,” said Mr Dekker.
“This whale kept its mouth wide open the whole way down as I am positive it felt the sea lion bumbling around its mouth.”
- The scientific name of humpback whales is Megaptera novaeangliae.
- These mammals are a species of baleen whale and are found in oceans around the world.
- Humpback whales can weigh around 30 tonnes and grow to about 16m long.
- They eat small fish and krill.
- Sea lions are part of a family of mammals called Otariidae, which also includes fur seals.
- Male sea lions can weigh around 300kg and be about 2.4m long. Females weigh around 100kg and are about 1.8m long.
- Sea lions eat fish, squid and octopus.

Work with a partner and write a short and catchy free-verse poem from the perspective of either the whale or the sea lion about this amazing encounter. It could start with something like:
There once was a small little sea lion …
There once lived a ginormous humpback whale …
Or start it totally different if you’d rather.
