Currently, Henry is focusing on the taxonomy of leptothecate hydroids [Leptothecata (=Leptomedusae, Thecata), Anthoathecata (=Anthomedusae, Athecata) and Siphonophorae are the three main groups of Hydroidolina (=Leptolinae), a clade of hydrozoans]. Representatives of Leptothecata are present in all marine environments worldwide and include more than half of all known extant (>3,800) hydrozoan species. One objective of Henry’s research is to address unresolved taxonomic problems of the hydroid fauna of coastal British Columbia. Other projects include being part of a collaborative group of scientists from Canada and the U.S. studying the transoceanic dispersal of biota on the marine debris field from the catastrophic Tōhoku earthquake and tsunami of 2011. Anthropogenic, non-biodegradable floating materials in the open sea can provide substrates capable of lasting far longer in the ocean than most natural substrates. These materials create rafting opportunities for hydroids, and other benthic fauna, including potentially invasive species, to BC’s coast.
