cuttlefish : any of various marine cephalopod mollusks (order Sepioidea, especially genus Sepia) having eight short arms and two usually longer tentacles and differing from the related squid in having a calcified internal shell — Webster
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone. Cuttlefish also have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from 15 to 25 cm (6 to 10 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in mass. — Wikipedia

- Resilience to climate change? New study finds...on January 13, 2021 at 8:32 pm
With the impact of climate change increasing by the day, scientists are studying the ways in which human behavior contributes to the damage. A recent study at Walla Walla University, by a collaboration of researchers from Walla Walla University and La Sierra University, examined the effects of acidic water on octopuses, potentially bringing new insight into both how our activities impact the world around us, and the way that world is adapting in response.

Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3-D-printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military camouflage, soft robotics and flexible displays.
- Research reveals full extent of seagrass beds in...on December 8, 2020 at 3:15 pm
Students from the University of Plymouth have led new research showing that seagrass beds in Looe Bay, on the South Cornwall coast, are among the largest such habitats in the whole of Devon and Cornwall.
- Touch and taste? It's all in the tentacles:...on October 29, 2020 at 4:00 pm
Octopuses have captured the human imagination for centuries, inspiring sagas of sea monsters from Scandinavian kraken legends to TV's "Voyage to the Bottom of the Sea" and, most recently, Netflix's less-threatening "My Octopus Teacher." With their eight suction-cup covered tentacles, their very appearance is unique, and their ability to use those appendages to touch and taste while foraging further sets them apart.
- Researchers find cuttlebone's microstructure sits...on September 11, 2020 at 6:04 pm
Ling Li has a lesson in one of his mechanical engineering courses on how brittle materials like calcium carbonate behave under stress. In it, he takes a piece of chalk composed of the compound and snaps it in half to show his students the edge of one of the broken pieces. The break is blunt and straight.
