A curious fisherman has discovered a tiny new species thriving in a Victorian lake.
Matt Jenkins took out his camera and filmed after he hauled in his net and found thousands of the little shrimp wriggling inside. “I’ve never seen anything like it in my life," he said.
After collecting samples from Lake Tambo within the Gippsland Lakes, he shipped a number of preserved specimens to the Australian Museum.
That was back in 2018, now five years on scientists working at the museum have proposed the creatures be recognised as a new species of skeleton shrimp.
Three things you didn't know about skeleton shrimp
Skeleton shrimp have narrow cylindrical bodies and reduced appendages.
They are usually found in marine or estuarine environments.
There are around 400 different species of skeleton shrimp.

Why are scientists excited about the find?
Professor Shane Ahyong described the find as “exciting” because it shows there is much to be discovered in Australian waters, even in popular areas like the Gippsland Lakes.
“These tiny skeleton shrimps usually go unnoticed because they look like slivers of seaweed,” he said. “Still, we need to know about them because some species are important food for fish, others tell us about the health of marine ecosystems.”
What do the shrimp look like?
The Australian Museum found the shrimp appeared similar to other shrimp in the family Caprella, but there were clear differences.
Japan’s Caprella acanthogaster is quite similar, but scientists determined its Australian doppelgänger is much smaller and has different antennae.
