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)
Just in time for
#FossilFriday: Fossil constraints on the origin and evolution of #Platyhelminthes are surprisingly concordant with modern molecular #phylogenies:

Clare Booth, Erin Davies & team characterise the developmental onset of regeneration in the flatworm Schmidtea polychroa. #preprint

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?!
Scientists Find Mysterious, Oozing Black Eggs Almost 4 Miles Below The Ocean's Surface

(Edit: corrected subfamily).
Happy to spot this Hammerhead Worm (subfamily Bipaliinae) at Dairy Farm Nature Park, Singapore, on 3 Feb 2024. The area was moist enough to tempt this one to come out into the open for me to get shots.
Hammerhead Worms are predatory flatworms that feed on earthworms or mollusks.

"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."
#Flatworms can either regrow lost heads or reproduce sexually, not both
#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?

The fact that this 'discovery' has been ignored means that it has gotten uncritically picked up by several online databases.
