'It's one of the least known': A remote and dangerous Amazon river finally spills its secrets Legend has it that the Santiago river used to swallow the canoe of anyone trying to explore it. Now an indigenous community is discovering surprising species in its waters.

"Freshwater fish, such as those in the Amazon, are seriously threatened. Their populations have declined by 81% in the last 50 years and in Latin America alone, they have declined by 91%." 🌎 www.bbc.com/future/artic...

Phyllanthoid branching evolved only once but has been lost several times. Some species have kept the branching but ditched the leaves. Phyllanthus angustifolius of the Antilles has cladodes (flattened, photosynthetic branches). #Phyllanthaceae #TropicalBotany #Botany 🌾🧪🌱

Intentionally bought a fake fossil crab because of how well done it was. Some sort of cast with stone like material and weighted to give the proper feel

Fragmented remains of a bronze sword laid out on a dark surface, its blade hacked into multiple pieces. The broken segments show long, parallel ridges characteristic of the original blade, along with sections of the hilt and guard.

An intentionally destroyed #BronzeAge #sword found in a burial at Blaubeuren-Asch. Bronze Age weapons deposited in burials were often bent or hacked into pieces before placed into the grave, in this way they 'died' with the owner. Dating 9th century BC.

look at this beauty...

Thinking abut the unique terminal swords on the ends of dacentrurine stegosaur tails on this #FossilFriday . They really do seem to fully fuse over the tip of tail. How to reconstruct (no evidence for parascapula spines) and how many taxa? Is Wyoming's Alcocasaurus a dacentrurine?

OK, that Lias coprolite maybe isn't the most aesthetically pleasing example for #FossilFriday. In fact it looks a bit s**t. So instead here's some nice-looking Scottish coprolites from the Carboniferous Wardie Shales near Edinburgh which Buckland had made into a table. It's now in Lyme Regis Museum.

Sandhill cranes yesterday. I always stop when I see them. 🪶

A large Atlantic Giant Grouper. Grouper are at risk of size reductions due to overfishing

Today is World Fisheries Day, so for #FishOfTheWeek let's talk about a fisheries issue that is becoming more and more common, reductions in size of fishes due to fishing pressure. This may seem like a small issue but is in fact a major problem for many reasons

Auf der „Jagd“ nach dem Japanischen Schnabelwal (Mesoplodon gingkodens) Im Juni 2024 sichteten Forschende vor der nordwestlichen Baja California in mexikanischen Gewässern eine der seltensten Walarten der Welt: den Japanischen Schnabelwal (Mesoplodon gingkodens). Für mehr...

Im NordPazifik haben Wal-ExpertInnen 2024 erstmals lebende Japanische Schnabelwale (Mesoplodon gingkodens) beobachtet.
Die Story geht gerade schon durch die Medien, wegen eines hungrigen Albatros.
Die Beobachtungen sind allerdings aus anderen Gründen sensationell

A small fish sheltering on the lobes of a finger coral. It has a large, bright pink eye and part of its head is also pink; the rest of the fish is largely transparent but the spine and some internal organs are visible #UnderwaterPhotography #Nature #Wildlife #Macro #WildlifePhotography

This is a pinkeye goby (Bryaninops natans) from Anilao. Or maybe a purple-eye goby, depending on who you listen to. I think it's more pink :)

some of the bettas i picked up yesterday. once i got home i was like damn i shouldve gotten 10. now i think i should get 10 MORE. im definitely going to look for some more different types of females to add to this little group lol

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988 Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy ....

Close up on the head and front half of a Flying gurnard, a truly unusual fish that creeps across the sand bottom using specially modified fins. It has very large eyes that show refractive irridescence from my strobe, and is sort of polka-dotted in reds, browns and blues

Way too much politics on my timeline right now, deploying weird marine life image. :) Here's up close and personal with an unusually cooperative Flying gurnard (Dactylopterus volitans). Night dive, Ulua Beach Maui. 🌿📷🐟🦑

A red on top and steel blue cichlid seen from the side. The fish is below a large green leaf of an aquarium plant.

Trade in marine fish for aquariums includes threatened species, lacks oversight: Study The United States is the main market for “ornamental” marine fish, those that end up as pets in aquariums. Now, a new study of U.S.-based online retailers has found that nearly 90% of traded species…

Update on National Fish & Wildlife Foundation and partners’ Mississippi River floodplain restoration work!

Boarfish typically live in very deep water. They have a protrusible, tube-like mouth for pulling small invertebrates from the seabed and are often found in shoals over rocky or sandy bottoms in the Atlantic, Mediterranean, and other oceans.

Applications due by Dec. 1

A male Paralabidochromis sauvagei, a Lake Victoria endemic cichlid. The fish is ovoid in shape with a grayish head. The body is yellow with two deep black stripes.

The same fish, now a little larger with only blotchy stripes. It is deeper bodied now and swimming in front of another much larger cichlid of another species.

Same fish, three and a half months apart. He‘ll be even more beautiful when fully grown. 🐟 #photography #fishkeeping
