Biotalker Posted February 21, 2022 Share Posted February 21, 2022 I recently watched these short videos on Nostraca tadpole shrimp/ shield shrimp. I'm sure it has been observed a million times before, but I wondered how similar the behavior of these extant critters might be to trilobites, given their convergent anatomy. Eyes on top, mouths on the underside of a shield like head, multiple similar legs/gills along its ventral surface. So to see these crustaceans maneuver, eat and remarkably molt (middle of second video), I just imagine similar behavior from trilobites, those stony motionless objects of our endless fascination. 2 Link to comment Share on other sites More sharing options...
Ossicle Posted February 22, 2022 Share Posted February 22, 2022 They are brilliant, and an interesting biological analogy. Thank you for the vids. Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 24, 2022 Share Posted March 24, 2022 I find these very interesting. I was a bit horrified to find that they cannibalize each other if food is lacking. (Kids had a triops set when they were younger. ) Fascinating creatures, though.

Cannibalism is freaky on one level, but step back and think in much longer time frames, and its really just the species reaching out for life and continued exisitence, by sacrificing a few so the survivors can get Tinder dates and breed again.
