Today's mushrooms! I think they're deceivers of some sort (Laccaria sp.) #FungiFriends #Nature 🌿
A cluster of brown mushrooms. They have concave caps, revealing the lighter gills underneath. They are growing in woodland with dead leaves and pine needles on the ground, and illuminated by dappled sunlight

Sunset, from the weekend #NaturePhotography
A sunset in fine weather over a lake. The sun is not visible but pink cirrus clouds streak across a blue sky, which is reflected in the lake in the foreground. A dark line of trees on the far side of the lake separates the sky from its reflection.

Sweetlips time! These are Ribboned Sweetlips (Plectorhinchus polytaenia, most numerous, thin yellow/black stripes), Oblique-banded Sweetlips (P. lineatus, with the bold black lines/spots) and Goldlined Sweetlips (P. chrysotaenia, with no black on them at all). #MarineLIfe 🐟🌿 #Wildlife
A mixed group of fishes, hanging out in relatively deep water (which is why it all looks a bit blue). They are mostly silvery with yellow fins and either yellow or black stripes (or both). They all have notably thick lips  and large mouths. There are patches of reef and sand visible behind them.

Humphead Bannerfish (Heniochus varius). Pic from Anilao. 🐟🌿 #MarineLife #Wildlife
A brownish fish, shading to black on its belly and yellow at the tip of its dorsal fin. It has two prominent white bands, one running from its throat to the front of the dorsal fin and the other from the base of the tai to the tip of the dorsal fin. It has a hump on its face above the eyes. The very high dorsal fin gives the whole fish a triangular shape.

When you're taking a photo of a crab, and Nemo and his Mom come to see what's going on #MarineLife 🦀🐟🌿 #Wildlife #Photography IDs in alt
A green anemone, with a crab sitting on the surface on the right and two fish peering at the camera from folds in the anemone's structure.
The crab is white with red spots on its upper surfaces; it has relatively large claws.
The fish on the left has an orange face with a white bar behind its eyes; the rest of its body is in darkness. A small fish under the crab is similar but has a yellow face.

The anemonefish is Amphiprion sp. (can't tell the species from this shot as we can't see the whole fish. The crab is a Spotted Porcelain Crab (Neopetrolisthes maculatus). I have no idea what the anemone is.

Discworld QOTD, from Men at Arms
The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.
Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars.
Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.
But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.
This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.

There were a few mantas around when I visited Raja Ampat, but this was the least bad photo I managed. Obviously the really good encounter was the one where I left the camera on the boat, because that's always the way. Oceanic manta (Mobula birostris), Cape Kri #MarineLife 🐟🌿

Wake up, babe. The Prime Minister just dropped “hydronym”.
The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means “the lake is beautiful, the lake is big”.

The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America.

We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms. 

Canadians also know that naming reality means calling it Lake Ontario – then, now and always.
