The U.S. Geological Survey conducts critical sea lamprey research. Indeed, the various reports of choking in large herons 'suggest that death caused by attempted ingestion of large or unwieldy prey by Great blue herons may be an important factor when considering adult mortality and population dynamics of this and similar species' (Wolf & Jones 1989, p. 484). How many of us would have thought that "death caused by attempted ingestion of large or unwieldy prey by [[assorted predacious tetrapods]] may be an important factor when considering adult mortality and population dynamics of [[these]] species"?

They belong to a relic (primitive) group of jawless fishes called Agnathans. In humans, the precursors of B cells and T cells begin in the bone marrow but develop along different paths, reuniting in the spleen and lymph nodes, where they collaborate to mount immune responses and take down pathogens. haveencountered before.
