For #WorldOceanDay I thought I would share a print with both a vertebrate and invertebrate ocean species. This linocut and gel plate print shows the humpback whale swimming above and a close up of the whale below with six Coronula diadema barnacles.

The Coronula diadema name comes from its barrel and crown-like shape, which can grow to 5 cm (2”) tall and 6 cm (2.4”) in diameter. 🧵

#MarshMadness day 21
Two little isopods, Lirceus sp. They are not technically from a marsh they are from a spring, but the spring was rather tiny marsh-like so I am counting it.

Right now I am trying to get people to step up for our environment as the public comment period draws to a close on removing the National Environmental Policy Act. This will effectively destroy almost all environment protections in the United States. If you were worried they will destroy the National Parks for profit, rest assured this is the first step. By removing NEPA, they *will be able to*. Easily.

Please, go leave your comment (federalregister.gov/documents/), call your senators and congress, and keep fighting for nature.

#NewSpecies of ocean predator in the Atacama Trench

A new large predator (#Amphipoda) hidden at hadal depths of the #AtacamaTrench: Johanna Weston et al. tandfonline.com/doi/full/10.10

"Characterized by darkness and intense pressure, the ocean's #HadalZone seems uninhabitable, yet dozens of unique organisms call it home... A new study highlights one of those species... This #crustacean is the first large, active predatory #amphipod from these extreme depths"

Absolutely massive, lobster-like signal crayfish in the river Misbourne. These species were brought to the UK from North America to be farmed, but have escaped into the wild & infiltrated some of the UK’s wild rivers, where they are pushing out the smaller native species from their habitats.
