The shark emoji appears to be modelled after the great white shark, one of the largest and most deadly shark species in the ocean. Can be used to show hunger or that someone is untrustworthy.
The shark emoji was introduced in 2016 and released as part of the Unicode 11.0 standard. This emoji can be found under the
animals and nature category. Because the shark emoji has been around for quite some time, it should display correctly in the majority of operating systems.
