I read the tittle as "long failed tadpole shrimp" at first 😁
Few rather insignificant scientific points:
0:30 The third eye is out of focus on this picture. What people usually imagine as the third eye is actually dorsal organ. The third, naupliar eye is much smaller and is located in-between the anterior edge of the compound eyes.
2:07 Most populations that are commercially available at least, are either hermaphroditic or parthenogenetic females. Which means they have the same appearance, but there's selfing happening in some populations. Parthenogenesis seems to be more common in the maleless populations of T. cancriformis, while some other species have functional testical tissue inside them. There's good summary of this, with multiple sources listed in the introduction section of paper "Self-Fertilization and the Role of Males in Populations of Tadpole Shrimp (Branchiopoda: Notostraca: Triops), Horn & Cowley 2016".
Maleless populations seem to be more common further north or higher elevation you go, and the common hypothesis for this is that it was caused by the ice age or ice ages. Once a single egg from either parthenogenetic or hermaphroditic individual manages to travel into an newly appeared habitat left by receding ice sheet, the new population would then have much higher propagule pressure compared to those that need both males and females.
Terms related to this topic, in case anyone reading my comment gets more interested in this: monoecious/diecious, androdiecious, gonochoric/hermaphroditic, parthenogenetic, self-fertilization, automictic, apomictic,

Thank you for this information! Yeah, the modes of reproduction is a mess with Triops I couldn’t even begin to describe it.
