In an open pine rockland forest. Separate male and female plants. Thanks to Roger Hammer for bringing me to this spot.
A shrubby, herbaceous weed with potted plants. The last two photos are of a seedling, photographed about two weeks later.
Remnant patch of native habitat left on the margins of a pine plantation
This was invasive reported to USGS through REEF, collected by Lad Akins and myself. Before and after capture.
Very large (almost comparable to adult parrotfish) , only one individual seen in a channel with strong current. Distinct markings on face. Unsure of ID - no good suggestions from algorithm
I took some macro photos of whatever is growing on the Euphorbia nutans plants in this empty lot in Hell's Kitchen, adjacent to the West Side Line rail tracks. It's filamentous and grows on the leaves, stems, and cyathia.
(EN) Spiny Chromis - (FR) Chromis épineux
Acanthochromis polyacanthus, Pantar Island, Indonesia
the leftmost: A. caudobimaculatus
the rightmost: A. vaigiensis
the middle: A. sexfasciatus
"Abudefduf vaigiensis"
Scale rows between middle of spinous portion of dorsalfin base and lateral line 3.5
No black spots at caudal-fin base
"Abudefduf caudobimaculatus"
Scale rows between middle of spinous portion of dorsalfin base and lateral line 2.5
Usually with 2 black spots at caudal-fin base
These two point of differences can be seen from this photo.
As a result, the species of this photo is "Abudefduf caudobimaculatus".
Now, "Abudefduf caudobimaculatus" isn't synonym of "Abudefduf vaigiensis".
