Amphipods collected from a DFO survey program in Beaufort Sea.
Being fed upon by presumed C. verrucosa
Discovered when cleaning a tank at institute, presumably came in from the seawater intake.
Not great with juvenile salmonids — need confirmation
Not native to the shores of Massachusetts…but apparently this one found its way up:)

embedded in cement?? or silt? contemporary or fossil? found various times in the Rockaways.

Vu lors d'un relevé de pétoncle par MPO-Québec / Seen during a scallop survey by DFO-Quebec.
On underside of a boulder in a low intertidal pool. Fairly common at this site.
Found as is, in a low intertidal pool. 3rd image shows them swimming in a tide pool.
I think this one is the same species that I observed a few days ago in a tide pool on Pemaquid Point: https://www.inaturalist.org/observations/122361424
The last image shows entoprocts found under the same rock as these Ancula gibbosa and likely their prey.

Only individual of this species I found this morning.
5 mm long; spotted floating in a tide pool (2nd image). A second individual, 4mm long (4th image), was in the same pool. I was stoked to finally find this species!
Dug from subtotal sand. Collected six of these while looking for burrowing anemones. Not sure what they are. Remind me of Pinnixa
Juvenile redfish observed on a DFO Quebec Region scallop survey.
I found 10 of these, 2 to 4 mm long, on a very fine, filamentous green alga in a shallow, high intertidal rocky pool amongst patchy salt marsh.
Specimens match Gould's (1870) description and illustrations of this species (as Calliopaea fuscata) from Boston Harbor.
Eggs at the bottom of a shallow pool, with a sample in a vial shown close-up in the 2nd image and a sample at the bottom of a plastic dish in the 3rd image. For scale, the markings on the bottom of the dish in the 3rd image are shown next to a mm scale in the last image. The eggs were therefore approximately 0.15 mm, or 150 microns, in diameter.
ID based on color, size of eggs, and proximity of spawning males.
Spotted swimming mid-day in water a few inches deep.
Found on duxbury beach up by the rocks near dunes while looking for snowy owls, hoping someone can at least narrow down the ID, it is very large
Maybe? Parasitic (or at least hanging on tightly) on a live Porcupinefish that maybe had been tortured by dolphins, hence floating upside-down on the surface of the sea.
Along the waterline, still pulsating. Looks like Cubozoa, but we haven't seen a member from this class before and weren't aware they'd be in the N. Atlantic.
Henricia sanguinolenta (10 mm arm length) caught feeding on Halichondria panicea, which varies from yellow to green depending on the presence of symbiotic cyanobacteria and exposure to light. The sea star everts its stomach and digests the sponge tissue, leaving behind the intact skeletal architecture (composed of tracts of siliceous spicules). Part of the feeding scar caused by this individual can be seen to the immediate right of the star.
