Finally caught a decent video of a comb jelly in action! This is Bob, the biggest one in our facility. Bob underwent reverse development due to stress & transitioned from an adult (lobate) back to a larva (cydippid). Now Bob is developing back into a lobate again! Science is so cool 🤩 #ctenophore

I am excited to tell you about our new study led by Tyler Audet and in collaboration with Stefan Lüpold's group. Below you see two species. On the right is Drosophila melanogaster. On the left, Drosophila prolongata. Notice the highly exaggerated legs of the males in D.p! doi.org/10.1093/evol...
Two panel image of Drosophila prolongata and Drosophila melanogaster. In the top panel is a female of Drosophila prolongata on the left and a female of Drosophila melanogaster on the right. It shows that D. prolongata females are somewhat larger than melanogaster, and have spotted wings. Importantly the legs are proportional in each species.

In the bottom panel are males. On the left is a Drosophila prolongata male which is larger than all the other individuals, and has highly exaggerated legs in terms of width and length, and also has black stripes. In contrast male Drosophila melanogaster are much smaller than all the others, with normally proportioned legs.

Sometimes biologists will discover some remote mountain lake, fed by snowmelt & unconnected from any river system. And it will be teeming with fish. Of multiple species. The next question is, obviously: how did they GET there? And the answer, we think, is "duck poop."

An ancient Greek silver coin depicting a bee! 🐝 😍 Minted in Ephesus, 390-380 BC. Photo Getty Museum #Archaeology
A Getty Museum photo showing a silver tetradrachm (four-drachma coin) stamped in high relief on the obverse of the coin with a bee viewed from above, within a dotted border. It is dark grey silver against a lighter grey background. Relief details include legs, wings, antennae, segmented abdomen and sting. The Greek letters, Ε (‘epsilon’) and Φ (‘phi’), an abbreviation for ‘Ephesus’, are placed either side of the bee. Diameter 7 mm.

From the museum catalogue:
“The reverse shows the foreparts of a stag kneeling in right profile, looking back towards a palm tree. An inscription to the right reads ΚΑΡΝΩ[Ψ] (‘KARNO[PS]’). 
The bee, stag, and palm are all emblems of Ephesus, a Greek city on the west coast of Turkey. This city was an important center of worship for the Greek goddess Artemis, and the images on Ephesian coinage typically promote this association. The bee was originally the symbol of an early Anatolian goddess who the Greeks later identified with their goddess, Artemis; so close was the connection that the priestesses of the goddess were called "honey bees." The two Greek letters, Ε (‘epsilon’) and Φ (‘phi’), are an abbreviation for Ephesus. The palm tree alludes to Artemis' birth beneath a palm tree on the island of Delos. The stag – an animal sacred to Artemis – symbolizes the goddess' role as protector of wild animals, and may also refer to the sculptures that flanked her cult statue in the temple at Ephesus”
