Ed Hendrycks studies marine crustaceans known as amphipods.

Ed's expertise is in a group of crustaceans (like shrimps, crabs and lobsters) known as amphipods. There are about 10 000 species described worldwide. Ed is especially interested in the taxonomy of deep-sea amphipods, those that live in depths below 3000 m. Even though these animals can be small, they play a critical role in recycling nutrients in the oceans, especially in deep-sea food webs. He has been on many deep-sea expeditions with international teams collecting these animals using gear that is lowered or towed along the bottom.
Ed is involved in two main research activities. The first one involves examining the biodiversity of animals that live on the bottom of the oceans (benthic). This project identifies, names, describes and examines relationships of species (the science of taxonomy).
Taxonomy is very important because all other biological disciplines rely on the correct names of species, whether used for conservation work or monitoring. The deep sea is a vast area that is mostly unexplored, so new species are regularly discovered.
You can see a list of the amphipod species that Ed has described by following the link below. Some of the publications used to describe these species can also be found there. These studies also support and increase the value of our collections as they add important type specimens to the national collections at the museum's research anc collections facility.
The other main focus of Ed's research takes place in the Canadian Arctic, mostly centered in the Beaufort Sea, an area known for oil and gas development. Ed is studying the communities of invertebrates that live on the seabed. The work investigates the diversity of life, the abundance of each species and how that is related to bottom features and water currents in the ocean. Some areas are rich in life and may need special conservation as biodiversity hotspots.
These studies attempt to get a better picture of biological processes in these fragile areas that compete with oil and gas development. With increasingly warmer sea temperatures and less ice cover in the Arctic, an increase in potential shipping may also impact the animals that live on the bottom.
Ed co-oversees the museum's lab where invertebrates are examined and works closely with our collection experts in the acquisition of new specimens and any inquiries relating to amphipods. He is also active in public outreach events hosted at the museum.
