Coelacanths (pronounced SEAL-uh-kanth) are primitive-looking fishes, survivors from the dinosaur-era to modern date. As far we know, only two coelacanths species are know, found in coastal waters of South African and Indonesia.
Researchers believed coelacanths has a maximum lifespan of 20 years,
placing the coelacanth among the fastest growing
marine fish. But these findings are at odds with the coelacanth’s other known biological features including slow metabolism, ovoviviparity, and low fecundity, typical of fish with slow life histories and slow growth.
Now, new methods for ageing coleacanths using scale ring growth reveals these prehistoric fish may live a centenarian life, but also, its life history is among the slowest of marine fishes, with 5-years gestation, and reaching sexual maturity at 50 years, the study found.
As long-lived species with slow life histories are extremely vulnerable to natural and anthropogenic perturbations, researchers aims that coelacanths may be more threatened than previously considered.

My work is so fucked now bc friday/Saturday its just me n one other guy. If it wasn’t i would call in sick today bc it’s raining and i have a headache. Can’t even complain bc Sunday/Monday it’s literally just one person though if i was her I would just not go if i was sick and not tell anyone
The Jetsons takes place in 2062, and George Jetson is 40 years old, which means that somewhere right now George Jetson is being conceived.
Actually, Google tells me George Jetson’s birthday is August 27, which means his parents are going to get successfully nasty this year’s Thankgiving Weekend.
Mark your calendars.
before tumblr existed did people tell these kinds of discoveries to a trusted friend or did they keep it all inside
Nobody likes statistics my friends w cars get soo mad when they tell me its dangerous to walk or take the bus home at night and i remind them it’s statistically much safer than driving chjcfthk
Horsehair worms, aka hairsnakes or Gordian worms, Order Gordioidea, Phylum Nematomorpha. Found throughout the world.
Although alien in appearance, these worms are parasitoids of arthropods in their larval stage and are not harmful to humans or other mammals. Adult worms are free-living, meaning they do not require a host, and they do not feed. Most are only a few inches long, but in extreme cases they can reach over two meters in length while remaining only 1 to 3 millimeters in diameter.
