In the laboratory, hydroid
colonies were placed in shallow flow-through water tables for 2-3 d.
Consider the hydroids
and their to-merge-or-not-to-merge dilemma.
2013 Sertularella calderi Hydroid
Dale Calder, Curator Emeritus, Invertebrate Zoology
Shallow depths of relatively high diversity (i.e., at 5 m depth) were dominated by hydroids
, encrusting sponges, and anemones (e.g., Corynactis rubeola).
In contrast, windward roots were dominated by filamentous algae (60-75% cover), fleshy algae (5-35% cover), and small hydroids
Amiloride appeared to be weakly inductive to larvae of the hydroid
Hydractinia echinata: a 600 [micro]mol [l.sup.-1] solution of amiloride in seawater induced ~30% of the tested larvae to metamorphose (Berking, 1988).
Doto form A is the most common Doto in the southern California bight and is commonly observed subtidally on campanularid hydroids
growing on kelp and other macroalgae.
Norwegian high-tech group Kongsberg Gruppen ASA said on Wednesday (12 December) that its subsidiary Kongsberg Maritime AS has agreed to acquire the US company Hydroid

perisarc: a chitin- and melanin-reinforced composite with DOPA-iron(III) complexes.
The worm was retained when both ends were approximately equidistant from the center of the hydroid
's mouth, and swallowed into the gastrovascular cavity still with the free ends moving (Figure 5A-D).
Studies on southwestern Atlantic intertidal hydroid
communities are rare, but include distributional inferences for the Brazilian tropical-subtropical coast (Rosso & Marques, 1997), and ecological assessments of seasonal richness, abundance, zonation and substrata for southern temperate waters (Genzano, 1994; Genzano & Rodriguez, 1998).
