Pulpo fiction: at Ripley’s Aquarium, the enormous Pacific octopuses act like puppies

Launch the Kraken!

The stuff of nightmares for many individuals, the octopus has been depicted in literature and artwork for hundreds of years as terrors of the ocean.

Prathamesh Kulkarni needs to dispel that fable. “Octopuses should not some fearsome sea monsters who get pleasure from chomping on fish and ships,” says the aquarist answerable for the exhibit at Ripley’s Aquarium of Canada on Bremner Boulevard. If something, Spaghetti and Noodle – the enormous Pacific octopuses in residence – are extra harking back to puppies.

“Bizarre as it could sound, they each like water being sprayed or trickled on them,” Kulkarni says. Whereas Spaghetti, a two-year-old male, loves his toy watering can, Noodle, a seven-month-old feminine, enjoys head pats and tickles. “Spaghetti,” Kulkarni says, “is extra into exhibiting off his power and will get right into a tug of warfare with me for his feeding pole – and most of the time, wins. He would maintain on to it for some time after which simply drop it on the backside of his tank for me to fish it out later.”

In accordance with Kulkarni, big Pacific octopuses have gotten plenty of consideration because the documentary “My Octopus Teacher” began streaming on Netflix. And when individuals discover out he works with them, he says, “(they) react with awe and curiosity.”

The most important of the species, big Pacific octopuses normally weigh round 33 kilos, though they will develop upwards of 110 kilos. Spaghetti, who has been with Ripley’s since July, weighs 44 kilos.

It takes these predators one-tenth of a second to vary color, permitting them to mix with their environment and turn into simpler hunters. Since big Pacific octopuses can solely be stored with sure different species, Spaghetti shares a tank with striped surfperch, anemones and starfish. Noodle, a five-pound juvenile who arrived at Ripley’s earlier final yr, shouldn’t be but on show. She is going to reside alone in a holding tank till Spaghetti goes into senescence and might be retired.

Native to the north Pacific area, these octopuses should not endangered, Kulkarni says, however face threats together with air pollution and overfishing of their prey: shrimps, clams, lobsters, crabs and scallops. Within the wild, they like cool water, low mild ranges, rocky terrain and caves the place they will disguise, all of which is replicated within the octopus exhibit’s 12,000-litre tank.

Clever and sentient animals, they will acknowledge human faces. “Experiments have proven than octopuses can inform people aside,” say Kulkarni, who provides that they will additionally kind bonds with their handlers. “Each Noodle and Spaghetti seem like so much calmer once we are interacting with them.”

Noodle, he provides, seems to have taken a dislike to somebody on the group. “3 times now,” Kukarni says, “I’ve seen Noodle begin to siphon and squirt water as that exact employees member got here near say hiya.”

An authorized diving teacher who has labored with sharks, rays, eels and jellyfish, Kulkarni joined Ripley’s as a diver in 2018, transferring on to the husbandry group in 2020. The first aquarist for the enormous Pacific octopus tank for the previous six months, he’s liable for monitoring well being and sustaining the cleanliness of the tank and its water chemistry.

Kulkarni and assistant aquarist Caroline Dyer additionally do coaching and enrichment. “Coaching for them is generally to get them used to getting in a bucket and staying there – or a web for Spaghetti, as he’s too large for a bucket – so the vet can take a look or in the event that they should be weighed,” says Kulkarni. Each interplay with the aquarist is a type of enrichment, together with feeding time, which Kulkarni begins by placing a goal within the water and splashing 5 occasions – the cue for them to return over. “They are going to then begin feeling my hand with their suckers,” he says, “which not solely provides them a robust grip, but additionally sense of style and odor.

“About 66 per cent of octopuses’ neurons are of their arms, which may additionally function greater than 2,000 suckers,” he provides. “That’s why typically, they’re mentioned to have 9 brains – one essential centralized mind and one from every arm.”

Regardless of being raised in captivity, each Noodle and Spaghetti are excellent at foraging, a talent their handlers hold sharp by zip-tying meals to crops within the tanks. “It’s all the time passed by the subsequent day,” Kulkarni says. “They’ve found out twist and switch to open a ball with meals in it, and Noodle can open lid on a plastic jar to succeed in for meals inside.”

Kulkani’s job shouldn’t be with out danger: octopuses use their sharp beaks to inject venom of their prey. “One must be cautious to not put their hand proper by the beak,” he says. However that hasn’t stopped him from diving into the tanks as soon as a month to rise up shut. “It’s a relationship of belief. I want to imagine that (we’re) greatest associates.”
