Day 18 #SciArtSeptember prompt cenote, or the limestone sinkholes accessible by ground water, a term originally only used for characteristic features in the Yucatán, Mexico and now applied more broadly to karst features anywhere, including in Australia, where fascinating but endangered stygofauna: aquatic animals who live underground, can be found. This is a hard-carved and hand-printed linocut 🧵

Rare giant "shrimp" is more widespread than previously believed, new findings reveal https://phys.org/news/2025-05-rare-giant-shrimp-widespread-previously.html

The supergiant #amphipod Alicella gigantea may inhabit over half of the world’s oceans https://royalsocietypublishing.org/doi/10.1098/rsos.241635

"#Amphipods like A. gigantea are #shrimp-like #crustaceans known for their narrow frames and a signature hump-backed curl in their posture. They roam the #DeepSea, from the abyssal depths (3,000–6,000 m) to beyond hadal zones (>6,000 m)"

#MarshMadness day 15

What does this funky thing have to do with marshes?! Well, this is an amphipod, genus Crayngonyx. They inhabit springs (including cave springs), but also can be found in marshes!

A new large predator (#Amphipoda) hidden at hadal depths of the #AtacamaTrench: Johanna Weston et al. https://www.tandfonline.com/doi/full/10.1080/14772000.2024.2416430

"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"

Researchers discover new ocean predator in the Atacama Trench

Characterized by darkness and intense pressure, the ocean's hadal zone seems uninhabitable, yet dozens of unique organisms call it home. Each species discovered there adds a crucial piece to the puzzle of how life has evolved and even thrives in one of Earth's most extreme environments.

Next up for #InsertAnInvert2024 is stygofauna: aquatic animals who live underground. This is a hard-carved and hand-printed linocut print of a little semi-transparent, white amphipod crustacean in the Neoniphargidae group from the Pilbara. This is a large, dry, sparsely populated region in northern part of Western Australia which is a global biodiversity hotspot for subterranean fauna 🧵1/2
