tumblr used to be a high throughput reef ecosystem but then they banned titties and now we’re like an ecosystem in the abyssal sea floor just quietly chugging along, cycling through nutrients at a much slower rate.
then every once in a while a some huge news comes along like queendeath and it’s like a whale fall, we come crawling out of the woodwork like isopods, hagfish, and burrowing worms to feast on the memes for years
it’s been almost two years since destiel-putin-election and we still linger around those bones like limpets

"Any good gardener knows what a good de-weeding can do for a vegetable garden. As it turns out, it’s much the same for coral reefs.
Following a volunteer “sea-weeding” program launched in Australia, scientists are witnessing compounding coral recovery both in quantity and diversity, and suggest that this simple method has the power to transform degraded reefs overrun by macroalgae.
In a balanced ecosystem, macroalgae is kept in check by the size and health of corals, but as extreme weather events or coral bleaching causes some sections of reef to die, macroalgae has no other neighbor keeping a check on its spread.
Over a period of three years, the joint Earthwatch Institute program led by James Cook University Senior Research Officer Hillary Smith and Professor David Bourne, also at JCU and the Australian Institute of Marine Science, has organized volunteer citizen scientists to help remove macroalgae at two experimental reef sites.
The results of the first three years of work and study have now been published in the Journal of Applied Ecology, and they show a 600% increase in coral recovery rates.
“It’s just like weeding your garden,” Smith said. “Every time we return, the seaweed is growing back less and less, so this method could provide lasting benefit without requiring endless effort.” ...
The importance of the study, Smith details, is that a lot of reef recovery efforts globally are powered by expensive, high-tech, and experimental solutions. The study hoped to show that manual de-weeding was just as effective, and thereby encourage organizations or nations that lack the tech or funding of a country like Australia to pursue sea-weeding as a way of protecting their corals.
“We have yet to see a plateau in coral growth within these plots at Magnetic Island, which is characterized as one of the degraded reefs on the Great Barrier Reef,” Smith said. “We also found an increase in coral diversity, so this method is benefitting a wide range of different coral types.”
Smith said her team are now scoping other locations where the sea-weeding technique could be useful, including the Whitsunday Islands, which are home to a different species of predominant seaweed.
They also want to employ them in French Polynesia, Indonesia, and even Singapore, where experts have identified out-of-control macroalgae spread along coral reefs."

Most species of sea snakes spend their entire lives in the ocean. To move in this marine environment their bodies have adapted to be tall, thin blade shapes with long paddle-like tails. They cannot breathe underwater, but their lung extends almost the full length of their body to help them retain oxygen underwater and with buoyancy control. BBC

Meet the Caribbean reef octopus (Octopus briareus)! This reef-inhabiting cephalopod lives in warm shallow waters, spanning southern Florida to the Caribbean, through to South America’s northern coast. It’s distinguished by its eye-catching blue coloring, but this master of disguise can change its looks in an instant. Like other octopuses, it uses pigmented cells in its skin, called chromatophores, to alter its appearance. When confronted by a foe, such as a shark, it may emit a cloud of unpleasant-tasting ink to deter its enemy from further pursuit.

spinner sharks!
Tumblr media Tumblr media Tumblr media Tumblr media
spinner sharks are sharks which live in many subtropical waters, such as the mediterranean and the gulf of mexico!
these sharks get their name from the way they spin out of the water to catch prey
they prefer shallower offshore waters no more than 350 feet deep!
spinner sharks grow from 6–10 feet in length
they grow roughly 2 inches a year until maturity, for 10-20 years!
spinner sharks can leap up to 20 feet in the air :]
