The closest comparisons available in the literature are the gastropods Alviniconcha and Ifremeria and another organism with a large trophosome, the tubeworm
Riftia; these organisms all have maximum uptake rates at relatively high temperatures, closer to our experiments at 25 [degrees]C.

and Says mud crab.
In Virginia, areas not under clam nets were numerically dominated by the cellophane tubeworm
Spiochaetopterus costarum oculatus (Webster, 1879), whereas in New Jersey ampeliscid amphipods (Ampelisca spp.) dominated these habitats.
Where necessary, encrusted material such as mussels or tubeworm
conglomerates was selectively dislodged to check for underlying nests.
"But it wasn't until human eyes saw shimmering water flowing under a tubeworm
'bush' that we really understood how special Jaco Scar is," Levin added.

The removal of the barrage will mean that congoli fish (Pseudaphritis urvilli) will once again be able migrate to the estuary to breed, and tubeworm
encrustations on tortoises will also start to disappear as salinity levels drop.'
It's found in marine tubeworm
cement, which indicates that the ingenuity of nature is equaled by the curiosity of biologists who ferret out interesting materials from all over the living world.
Experts also found a tubeworm
at a depth of 990m on the seafloor in one part of the Gulf of Mexico.
Sections of the gravel substrate contain dense patches of sponges, hydroids, bushy and encrusting bryozoans, colonial ascidians, and the lacy tubeworm
(Filograna implexa) (Collie et al., 2000a; Valentine et al., 2007).
They are built by the tubeworm
serpula vermicularis, and twist upwards off the sea bed.
The photo shows a Mediterranean meadow of Posidonia oceanica with schools of fish, (sparids and serranids) and by a tubicolous polychaete, the spiral tubeworm
(Spirographis spallanzani), with its branchiae extended.
