Leopard shark definitely has more patience than me when it comes to doing origami. I attempted a crane but gave up when my crane did NOT look like the foldings even though I followed exactly what they said.
Anyway, the leopard shark (Triakis semifasciata) - NOT to be confused with the Zebra shark (Stegostoma fasciatum) - is a species of houndshark. They're really cute and are currently listed as least concern on the IUCN red list. Let's leave it that way.
