Strange Chinese delicacy of the week 9

Better one day late than never…!

Well done to Jane, Dom and Carlton for last week’s sea cucumber answer.

They are amazing things, sea cucumbers. “A remarkable feature of these animals is the catch collagen that forms their body wall. This can be loosened and tightened at will, and if the animal wants to squeeze through a small gap, it can essentially liquefy its body and pour into the space. To keep itself safe in these crevices and cracks, the sea cucumber hooks up all its collagen fibres to make its body firm again.” The Chinese love them too, as you can imagine. “In China, many commercial sea cucumbers are farmed in artificial ponds. These ponds can be as large as 1,000 acres (4.0 km²), and satisfy much of the local demand”

This week’s delicacy is very famous, but it may not look like it sounds. Clue: I might tweet about it.
