Dead Nomamyrmex esenbeckii army-ant major engaged in battle with dead Atta texana worker. I found 6 dead esenbeckii army ants on top of a large Atta texana mound (the 6 dead workers in third photo), and one of these esenbeckii majors had died while battling an Atta texana worker (first 2 photos). I had written before that I started to look for dead Nomamyrmex on top of Atta texana mounds, and this is the second time I found Nomamyrmex army ants associated with Atta texana. I searched during two days about 40 Atta texana mounds carefully for the presence of dead Nomamyrmex, and this is the only Nomamyrmex I found among these 40 Atta texana mounds.

Interestingly, this Nomamyrmex observation today was only about 70 meter distant from where I had found dead Nomamyrmex a year earlier in March 2022, at that time on top of a near-abandoned Atta texana mound (see here https://www.inaturalist.org/observations/108890321). It appears that a single Nomamyrex esenbeckii colony may have hounded the Atta texana at this site repeatedly (maybe continuously?) during the last year.

I used the Watkins 1977 & 1982 keys to ID this to esenbeckii (e.g., post-occipital sulcus present).

Is it a fish? Is it a slug? Is it a fishy anemone? I do not have a clue what this is!

It is about 30mm long and there were a few of them in the sand - outgoing tide nearly on the turn. Most were buried and only the "fan fin" was showing.

Resting on the wet sand, when the sand collapsed it arched it's face upwards (2nd and third photos) and seem to spawn capsule from somewhere - there are 2 floating in the 4th pic.

Totally hypnotic, by the time my sister-in-law and I carried on the brother had walked 2kms away from us!

Found at Quinta Mazatlan in McAllen Texas. This is the first record of Coelioxys (Glyptocoelioxys) totonaca within the United States -- and the first record of its subgenus in Texas. ID by John L. Neff of the Central Texas Melittological Institute.
