Phronima, family Phronomidae, order Amphipoda, Gulf of Aqaba, north Red Sea

This is a genus of small deep sea hyperiid amphipod crustaceans.

Phronima rear their young, and sometimes live in, the empty "tunics" of tunicates (sea squirts), which they kill and eat.

They are also known as "pram bugs" and "barrel shrimp".

Uncharismatic Fact of the Day

The next time you hit the beach, keep an eye out for sand hoppers! Only 1-2 cm (0.39-0.78 in) long, these tiny crustaceans can jump as high as 40 cm (15 in) or a distance of over a meter (39 in)! Their remarkable leaping abilities come from their tails, which sand hoppers tuck under their bodies and then flick out like a spring board.

Carnivorous and non-picky, Themisto are formidable predators. Many smaller planktonic organisms have met their end at that long pair of limbs which work like folding razors.

Did river invert sampling today! It was very cool, also got to see some very nice inverts other than the river ones, and maybe some planarians that aren't pictured here since I couldn't get them off the rock I saw them on

[t00thpasteface]

Genuine curiosity, what's the difference between isopods and amphipods?

oh hey, i remember this from last semester!

it's right in the name actually! crustaceans in order Isopoda ("single foot") generally only have one kind of appendage on their thorax-- they're pretty much all the same shape and oriented in the same direction. by contrast, crustaceans in order Amphipoda ("both foot") have some pairs of limbs facing forwards and some facing backwards, each with different shapes/uses.

of course, as with any taxonomic group, it ultimately comes down to genetic ancestry/similarity, and simple physiological appearance is not what determines the taxa!

[todropscience]

While this species is new to science and lives in one of the remotes habitat in the world, the hadal zone, it is not exempt from plastic pollution, one individual was found to have a microplastic PET (Polyethylene-terephthalate) fiber in its gut. PET is a very common plastic usedto make water bottles, food packaging and fibers clothings. This species was named  Eurythenes plasticus after this finding.

[vyragosa]

not bullshitting it random because you have to understand that amphipoda specifically is a diverse group of small shrimp-like taxa that brood their young in a POUCH the marsupium with no independent larval dispersal stage

with kojima’s very particular fondness for his cryptiobiote, extensive research on marine life, it could absolutely not be a coincidence that the design is alone is mixing BB + amelie + higgs = > carrying life at the depths of the abyss

que orden de crustáceos existen en el supra litoral oceánico español

En el supralitoral oceánico español, se pueden encontrar diversos órdenes de crustáceos que están adaptados a vivir en la zona intermareal superior, es decir, en la franja de terreno que se encuentra por encima del nivel de marea alta. A continuación, mencionaré algunos de los órdenes de crustáceos que se encuentran comúnmente en esta zona: Orden Amphipoda: Los anfípodos son crustáceos pequeños…

Dissecting the Kenhub Atlas: Insights from Editor Mike Pascoe | TAPP 144

Mike Pascoe joins host Kevin Patton in Episode 144 to chat about Mike's experience in editing the new Kenhub Atlas of Human Anatomy. We go behind the scenes to see how this new kind of anatomy atlas was developed. Let's see how those decisions get made and how the learning perspective gets incorporated into anatomy manuals. And we explore diverse representation in anatomy images and why we won't find any eponyms in this atlas. We also have a brief remembrance of our friend David Allard.

  Remembering David Allard

3.5 minutes

In this segment, Kevin reflects on the recent passing of a friend and colleague, David Allard of Texas A&M University-Texarkana, who was an exceptional educator and human being. Kevin finds inspiration from David's generosity and commitment to his students and peers.

  Introducing Mike Pascoe

2 minutes

In this segment, we introduce the guest for the episode, Mike Pascoe, who is an associate professor of anatomy at the University of Colorado Anschutz Medical Campus. Mike is involved in developing and delivering anatomy curricula to various student groups and has a research interest in innovative learning approaches. He's the editor of a new learning resource, the Kenhub Atlas of Human Anatomy.

  A New Take on the Human Atlas

13 minutes

Editor Mike Pascoe describes his new Kenhub Atlas of Human Anatomy. First, we look at the relationship of the innovative, disruptive Kenhub website and this new print manual. Mike mentions how Kenhub often ranks high in web searches and how they aim to make their atlas concise and lead readers to a larger library of materials using QR code scanning. The convenience and accessibility of QR codes, easily scanned with smartphones, and the pocket-sized form factor of the atlas, making it easy to carry around in a lab setting.

  Debriefing and Predictions Ahead
