Description

Holotype (CASIZ 182590), 33 mm long as shown here, on which Terry Gosliner based his 2010 description of this species (as Flabellina goddardi). I found it on a calm and bright overcast morning crawling in the open in a low intertidal pool at Tar Pits Reef. The 2nd image shows the egg mass, 14 mm in diameter, laid by this individual on 10 May 2008. The uncleaved zygotes averaged 65 microns in diameter, were packed one per capsule, and took 7 days at an average of 16 degrees C to develop into hatching planktotrophic veligers. The 3rd image shows, in right ventro-lateral view, one of the veligers just prior to hatching and with a shell 105 microns long.

Unlike most specimens of this species observed subtidally, individuals found intertidally vary in possession of white lines on the body and cephalic tentacles from completely absent (as in this specimen) to incomplete, to complete. With those white lines, subtidal specimens have occasionally been mistaken for Coryphella trilineata.

These crabs are quite common on the tidal flats in the North Eastham area, I've been seeing them for many years.

There's a paper, Phylogeny of the genus Pinnixa White, 1846 (Crustacea, Brachyura, Pinnotheridae) and allies inferred from mitochondrial and nuclear molecular markers, with generic reassignment of twenty-one species (By Emma PALACIOS THEIL & Darryl L. FELDER) - Link: https://sciencepress.mnhn.fr/en/periodiques/zoosystema/42/6 that contains a Morphological characteristic chart. The shape of the claws and male pleon align with Pinnixa cylindrica most closely.

There's another paper out there, THE OCCURRENCE OF PINNIXA CYLINDRICA (CRUSTACEA, PINNOTHERIDAE) IN THE TUBES OF THE LUGWORM, ARENICOLA CRISTATA (by John J. McDermott) - Link: https://www.jstor.org/stable/44112124 that describes Pinnixa cylindrica being found frequently alongside the Lugworm. There are many American Lugworm in the area as evidenced by their egg 'jellies'.

There are a few Cape-area Pinnixinae on iNat already, I believe these are also Pinnixa cylindrica:

I decided to dig a little ways down a burrow about 0.5 inches in diameter which felt like it had compacted/slightly cemented walls. Similar burrows in the area were very deep and had multiple entrances. All were in ~4 inches of water at dead low tide. I felt this fish fleeing headfirst down the hole and trapped it with my index finger against the burrow wall, maybe 7 inches down and pulled it out after digging down with my other hand to make some space to maneuver. I think the burrow continued deeper but I did not dig any more after pulling the fish out. I suspect that the burrow was made by the mud shrimp Upogebia affinis. I posted an exoskeleton from that species from the same location a little while ago and found another during this trip. I saw another goby maybe 1.5 cm long later in the day but didn’t catch it.
