A few more shots of the baby octopus 🥰🦑🦀
A baby octopus in a tidepool; it's light tan with many visible chromatophores. Its tentacles are wrapped around backwards, and it's sitting between a couple of mussel shells on some sand grains.

A starfish that reproduces in the most insane way possible... it rips off its own arm, and a whole new body grows from it.

🧠 Report on the zoological collections made in the Indo-Pacific Ocean during the voyage of H.M.S. 'Alert' 1881-2.
London: Printed by order of the Trustees, 1884.

[Source]
Illustration from an 1884 report on zoological collections in the Indo-Pacific by H.M.S. "Alert," showing detailed, labeled pencil sketches of three crab species: Euxanthus tuberculosus (A), Hypoecius punctatus (B), and Banareia inconspicua (C). The drawing highlights the crabs’ carapaces, claws, and leg structures with close-up views of their distinctive textures and anatomical features, such as tubercles and spines. The image reflects 19th-century scientific documentation methods linked to Darwinian natural history and species classification during exploratory voyages.

A new seamless repeat - Star Crinoids.

These fossils can be found worldwide, especially in areas where there is limestone and shale. And in the UK, they are sometimes called fairy coins. 🧚
