釣れたブルーギルを足元に落としたら、
コポッ
って音が聞こえてよく見たら何かの穴が…
もしかしてと思って振動させてみたらやっぱりタウナギ…
経験的にこう言う個体は振動に向かってどんどん出てくるので様子を見てみた。
めっちゃ引き摺り込む力が強かった。

Kinda going under the radar but someone caught a video of a sperm whale eating a “relatively intact” giant squid

Utterly incredible

Not all ammonites had nice spiral shells. Some of them, known as heteromorph ammonites, had very irregular shapes for their shells.

Nipponites are a classic example. They lived during the Late Cretaceous period. Their shells twisted and turned to roughly form a messy ball

@PaleoAnalysis Two toed sloths can be scary at times tho, they've got sharp canine teeth and their metabolism is faster than a three toed sloth
Here's a video of one fighting an ocelot

The #NazcaHighSeas science team observed this squid, which they suspect is an Ancistrocheirus lesueuri, or sharpear enope squid, during the first test dive of a recent expedition in the high seas off the coast of Chile. Happy #WorldSquidDay!

New wound care behavior in ants! Here we show how ants amputate the leg of injured conspecifics (a first in the animal kingdom)! Interestingly, amputations are not always the best strategy to care for a wound and ants have adapted their treatment accordingly. A 🧵... (1/6)

A new look at footage recorded by one of MBARI’s deep-sea robots during an expedition to the Gulf of California has revealed a new deep-sea squid that broods giant eggs.

Omnidens amplus, a 1.7 metre long lobopodian from the Cambrian of China, hunting Eoredlichia trilobites.

At the time, it was one of the largest lifeforms on the planet.

Prepare to meet one of the most beautiful fossils ever. A spectacular crinoid colony.

This Jurassic giant measures over 100 square metres & took 18 years to prepare! On display at the excellent Hauff Museum.

This was one of the 50 fossils featured in, LOCKED IN TIME.

Some amazing footage of a Northern Bottlenose Whale off Greenland! I've never heard of this sort of opportunistic scavenging behaviour documented from any Beaked Whales before, and CERTAINLY never seen footage of it!

Shimmering is a defence behaviour in giant honeybees, whereby bees on the nest surface flip their abdomen upwards in a Mexican wave-like process.

This BBC video provides some of the best shots of the phenomenon: https://t.co/a6OmaDFg3i

A horn sharks egg, the spiral ridges on the case provide it with a strong grip in rocky crevices ensuring stability even during turbulent surges and waves

Scallops use jet propulsion to swim

Water is drawn in by opening their valves, then rapidly closing (clapping)

This water is then pushed out of the mantle (body) through jets on either side of the rear hinge,

propelling the animal forward

Quels sont les deux points communs entre le Gange, l'Irrawady, l'Adelaide River et le Kinabatangan ?

Effectivement, ils sont tous des fleuves ! Mais ils ont un autre point commun ... ils abritent tous des requins !
