I thought this was the longest leech I've ever seen, at around 125mm.
WRONG!
It's not a leech. It's a Caenoplana coerulea, known as the blue planarian or blue garden flatworm according to Wikipedia.

One of the highlights of my day was when William Harland, a talented ecology undergrad here at #LincolnUniversityNZ, stopped by my office to show me his photos of temnocephalid flatworms. These distinctive squat tentacled flatworms live in colonies on NZ's freshwater crayfish, koura, and eat scraps left over when the koura feed. They apparently cause no bother to the koura.
William found these at Poolburn Reservoir in central Otago.
Amazing!

To find the subject of my PhD in the garden pond at my very Cambridge college, that made my day.
Planaria, genus Schmidtea, swimming near the surface:

A miniature swimming robot inspired by marine flatworms
EPFL engineers have developed a versatile swimming #robot that nimbly navigates cluttered water surfaces. Inspired by marine #flatworms
the innovative device offers new possibilities for environmental monitoring and ecological research. -

Pseudoceros #flatworms are pretty :) #biodiversity #iNaturalist www.inaturalist.org/observations... (I took these in Asian waters around 2024)

Already my favourite "PS of the Day" (a category which I introduce right now) in the lower part (no pun intended) of the Simply Science newsletter from @theeconomist.
The newsletter is mainly about fly brains, but(t):

Gutless, solar-powered worms genetically control their resident algae.
The tiny #flatworms called acoels seem pretty simple. Their internal organs drift freely in their shapeless bodies, which lack even a digestive tract.
Some acoel species host photosynthesizing algae that provide energy in exchange for safe housing, a classic #symbiosis.
These worms manipulate their live-in algae’s gene activity during their extreme act of regeneration.

When I was a child, I used to go through my Dad's #invertebrate #zoology textbook left over from college.
I remember being fascinated by the #worm you could cut down the middle and it would grow two heads.
Who knew this would be relevant to current events almost 60 years later?!

Dark eggs found on #ocean floor represent deepest free-living #flatworms ever observed https://phys.org/news/2024-01-dark-black-eggs-ocean-floor.html
#Flatworm cocoons in the abyss: same plan under pressure https://royalsocietypublishing.org/doi/10.1098/rsbl.2023.0506
"The black clutch of eggs was discovered by Yasunori Kano as he was piloting a remote undersea vehicle in NW Pacific. He collected samples at a depth of 6,200 meters. After initial testing, the researchers discovered that the eggs represented something rare—they sent a trawling ship for more specimens"

Parasite of the Day: Euglenaformis parasitica
http://dailyparasite.blogspot.com/2023/12/euglenaformis-parasitica.html"#Euglena and its kin are mostly free-living, photosynthesizing when the sun's out, absorbing organic matter from the environment when it's dark. But the ancestor of E. parasitica was not content with this mostly peaceful lifestyle, and has evolved to live inside the body of #animals. These #euglenids were found parasitising #ostracods & #flatworms in a rice field in #Ibaraki, #Japan."

#Planaria are freshwater #flatworms that have become a key model for studying #regeneration and #stem #cells, as they can regenerate any part of the body, even the head. But how does the animal know what part of its body is missing and what kind of tissue it needs to #regenerate?
