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.

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 (40% cover).
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

Marine
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).
