Can sharks vomit?
Sharks can actually vomit by hurling their stomachs out of their mouth, repelling the foreign item, and then re-swallowing their stomachs. Some sharks eat foreign items and fail to throw them up.
The kind of shark that you are reading about is the Tiger shark who is not only a large species of shark with more room in their stomachs, but also they are known to ingest anything and everything. Bigger sharks are less likely to vomit because smaller sharks have less room in their stomachs.
