Incoming FaceTime call from... some Japanese eels.
Keepers at Toyko's Sumida Aquarium, which has been closed since 1 March due to the coronavirus pandemic, are starting to worry about their garden eels.
The sensitive little creatures had become used to seeing hundreds of faces peering into their tanks.
Now the aquarium is deserted they've started to dive into the sand whenever their keepers walk past.
This makes it hard to check they're healthy.
The aquarium says the eels are "forgetting about humans" and is making what it calls an "emergency plea".
"Could you show your face to our garden eels from your home?"
Yes, they're asking people to call in for a sub-aqua video chat and remind the eels that humans are friendly.
"Creatures in the aquarium don't see humans except keepers and they have started forgetting about humans," the aquarium wrote on Twitter.
"Garden eels in particular disappear into the sand and hide every time the keepers pass by."
The eels are particularly sensitive - and the aquarium is keen to reacquaint the 300 eels it homes with humans so they can carry out important health checks on them.
It's placing five tablets facing towards the tank in a "face-showing festival" scheduled for 3 to 5 May.
Unfortunately, if you love eels but also love Google phones or PCs, you'll have to sit this one out - the aquarium is only offering the option to connect with the eels over Apple's FaceTime app.
Garden eel facts
Garden eels live in sandy burrows that they dig tail-first and coat with mucus to stop the burrow collapsing. They're some of the sea's little builders. When it comes round to mating season the males and females move their burrows closer to each other.
They live in colonies of several hundred and each eel has its own burrow - with the largest male usually living in the centre burrow, according to the Georgia Aquarium.
When we see them it's usually only a quarter of their body that is poked up out of the sand - the rest stays in their burrow. They rarely leave, even to mate.
You could say they're the original self-isolaters.
