Invasive Sea Vomit
In short
Invasive sea vomit is a common nickname for the carpet sea squirt, an invasive marine species known as Didemnum vexillum. It spreads across the seabed and attaches to boats and fishing gear.
In plain words
This is a colonial sea creature that grows like a thick, slimy carpet. It smothers local sea life and clogs up human equipment like ropes and hulls.
A simple example
A black Labrador named Sgiath uses her sense of smell to find small fragments of these sea squirts on the Scottish coast. This helps experts spot outbreaks before they spread too far.
Why it matters
It damages marine ecosystems by outcompeting native species. It also causes economic problems for fishermen by fouling their gear and boat hulls.
Easy to mix up
Do not confuse this biological term with actual vomit from a sea creature or a person feeling seasick.
