The high speed radular prey strike of a fish-hunting cone snail
2019年8月19日 · To visualize the trajectory of the radular harpoon during release within the translucent proboscis of C. catus, an individual snail was coaxed to extend its proboscis down a narrow seawater-filled chamber toward prey held near the end of the recording chamber (Figure 1 A,B; Video S1 in Supplemental Information, published with this article ...
Watch These Cunning Snails Stab and Swallow Fish Whole
2018年5月29日 · Cone snails launch their harpoons so quickly that scientists were previously unable to capture the movement on camera, making it impossible to calculate just how speedy these snails are. Now, using super-high-speed video, researchers have filmed the full flight of the harpoon for the first time.
The Deadly Harpoons of Cone Snails - Smore Science Magazine
3 天之前 · But the beautiful cone snail is one of the deadliest marine animals in the world. For example, the species Conus geographus has more than 100 toxins in its venom. Cone snails (genus Conus) are indigenous to reefs in the tropical waters of the Indian and Pacific Ocean zone.
Mechanism of prey capture in Conus pennaceus. Images of Conus …
By swiftly harpooning and injecting their prey and predators with such deadly cocktails, the slow-moving cone snails guarantee their survival in the harsh, competitive marine environment. Each...

2019年9月6日 · Radular teeth of cone snails resemble harpoons, with the hollow shaft acting as a conduit to deliver venom to the prey (see enclosed scanning image of the tooth of Conus catus). Fish-hunting cone snails use fast-acting toxins (the venom) and a …
The high speed radular prey strike of a fish-hunting cone snail
2019年8月19日 · We report here that the cone snail's prey strike is one of the fastest in the animal kingdom. A unique cellular latch mechanism prevents harpoon release until sufficient pressure builds and overcomes the forces of the latch, resulting in rapid acceleration into prey [2].

2004年10月19日 · A new study reveals that the fish-hunting cone snail immobilizes passing fish by firing a harpoonlike tooth at them. The entire process--from detecting the prey to stunning it--takes less than 300 milliseconds, making it one of the quickest captures known.
UCI Scientist Identifies Cone Snail's Strike as One of the Quickest …
2019年8月30日 · Using high-speed videography, the researchers determined that the radular harpoon can be propelled into prey within 100 microseconds, with a peak acceleration exceeding 280,000 m/s2 and a maximal acceleration exceeding 400,000 m/s2.

2019年8月1日 · We report here that the cone snail’s prey strike is one of the fastest in the animal kingdom. A unique cellular latch mechanism prevents harpoon release until sufficient pressure builds and...
How do cone snails shoot out a harpoon? - CK-12 Foundation
The fish-hunting cone snail fires a harpoon-like tooth at prey. Venom on the tooth can stun fish. The snail launches the tooth by a strong, fast muscular contraction. The entire process from detecting the prey to stunning it takes less than a third of a second, making it one of the quickest captures known to scientists.
