the sun at night

HI, I'm Sara. I'm too old to be on tumblr. This is mostly a fish blog but also herps and other general critters/stuff from the world. I am an almost fisheries biologist from NW Indiana. (The NW is important, ok). Someday, I would like to become a mountain hermit.

garter snakes perform mimicry to seem more dangerous than they are. in the first photo you can see how they flatten their necks to mimic a different venomous snake

Going through archives and holy shit just found this baby picture of my goldfish back when they fit comfortably in a ten gallon… 

I’m setting up a 54 in a couple months when I move. They are are much larger now.

Even if I don’t see you 
I can regain what we seek in the night 
Even if it’s really difficult 
I’ll dance my path with the wolves.

Australian Endangered Species: Largetooth Sawfish

By Peter Kyne, Charles Darwin University

Sharks and rays are some of the world’s most threatened animals, with a quarter of all species at risk of extinction. Among the sharks and rays, sawfish are some of the most threatened, with all five species listed as Critically Endangered or Endangered by the International Union for Conservation of Nature (IUCN).

The Largetooth Sawfish (Pristis pristis), previously known locally as the Freshwater Sawfish, is one of the planet’s largest fish, growing to over 6.5m in length.

The Largetooth Sawfish is a “euryhaline” species: capable of moving freely across a range of salinities from pure freshwater to the oceans. Its life cycle is complex and fascinating, encompassing a wide variety of habitats – floodplains, billabongs, creeks, rivers, estuaries and marine waters.

Young Largetooth Sawfish are born in estuaries before migrating upstream to spend their first 4-5 years of life in river systems. Locally they have been recorded up to 400 kilometres from the coast in the Fitzroy River. Upon nearing maturity they move back to coastal and marine waters.

Euglena | ©Rogelio Moreno G.

Remember the classic drawings of Euglena in Biology class when the teacher explained about the flagellate protists?

Well, this is a real Euglena as seen under the microscope. In this photomicrography you can clearly see the flagellum, the stigma (red), the nucleus (blue) with the nucleolus inside, and a couple of large chloroplasts.

The Fabulous Osmylids!

Not one of our best known insect families, though possessed of classy, photogenic larvae.

From the photographer: The long projections on the head are the mouthparts and are “thought to probe for chironomid larvae in softer sediments”. They are semi-aquatic predators that have a water repellant skin. (ref Gooderham&Tsyrlin - The Waterbug Book)
