In April, USGS scientist Alexis Weinnig and other scientists collected eDNA during a deep-sea exploration aboard the NOAA Ship Okeanos Explore as part of the NOAA Ocean Exploration expedition, EX2301. During the trip, a Remotely Operated Vehicles (ROV) collected water that was filtered on board the ship for eDNA left in the water by nearby organisms.

Alexis Weinnig, USGS Biologist, and NOAA Scientist Ashley Marranzino work together to filter seawater for eDNA from a CTD rosette while aboard the NOAA Ship Okeanos Explorer. eDNA will allow for the detection of biology in the surrounding seawater.

Toads (Anaxyrus sp.) lay their eggs in long thin strands, which helps distinguish them from other anuran species which may lay their eggs singly or in round clusters.

These are the eggs of the southern leopard frog (Lithobates sphenocephalus). Leopard frog eggs are laid in tight clusters, and they have contrasting colors of black on the upper side and white on the underside.

Blotchy bass syndrome (BBS) is the presence of hyperpigmentation (melanosis) on the external surface of black basses. This condition has received increased attention from anglers and resource managers in recent years and is a popular topic of discussion and reporting on angling websites and blogging platforms.
