as funny as it is to say, "there's no such thing as a fish" is not actually true

"science doesn't know what a fish is" is really not true

"fish" is not a monophyletic category. there is no common ancestor of everything that we call a "fish," and none of the things that we don't

"fish" is a paraphyletic category -- and a useful one! marine biologists use it! "fish" describes a general body plan and lifestyle. it is useful to be able to talk about coelacanths and tuna in a shared category, though coelacanths are more closely related to us than to tuna.

where this bugs me is the repetition of the idea that "scientists" are hidebound and uncreative, unable to comprehend anything that doesn't conform to a specific idea of categorization -- when this is fundamentally untrue! we know perfectly well what a "fish" is. the fact that it's a paraphyletic group is only confounding to pop science, as a funny factoid, not to anyone who actually understands what a paraphyletic group is.

"Over 10,000 square miles of additional protected area will be added to the Heard and McDonald Islands in Australia’s far southern territorial waters.

Coupled with other expansions of existing marine sanctuaries, it puts Australia on course to have 52% of its ocean territory protected, more than any other nation, by the end of the current administration’s term.

“This is not just a huge environmental win for Australia, it’s a huge environmental win for the world,” said Australian Environment Minister Tanya Plibersek. “This is a unique and extraordinary part of our planet. We are doing everything we can to protect it.”

Located over 2,000 miles south of the Australian continent, Heard and McDonald Islands make up about 144 square miles of volcanic terrain that represent one of the most remote places on Earth.

They are important breeding grounds for 19 species of bird, including 4 species of penguins, but dozens of other bird species take refuge there. It is a UNESCO Natural Heritage Site, and a RAMSAR Wetland in addition to being an Australian national marine sanctuary.

The quadrupling of the sanctuary borders amounts to 11.5 thousand square miles, (30,000 sq km) of additional protection, but represents one-tenth of the total proposed expansions of marine protected areas.

Under the current guidance, prepared by nationally sanctioned scientific surveys, the total marine protected areas will make up an area the size of Italy.

The current administration of Prime Minister Anthony Albanese is seeking to establish a new environmental protection agency, as well as set a high bar for the country’s commitments to an international philosophy of conservation governance known shorthand as “30×30” or “30 by 30,” which states that to prevent the worst effects of general environmental degradation worldwide, 30% of land and waters should be under protections. Often the second thirty refers to a hypothetical 2030 deadline."

GULLS WILL DECIDE WHAT TO EAT BY WATCHING PEOPLE 

Herring gulls (Larus argentatus) can perfectly thrive in coastal  and urban landscapes, however, these birds will steal your food as soon as you are distracted. Urban gulls pay attention to human behaviour in food-related contexts, and will mimic what humans almost all the time, a new study shown.

In a simple test, researchers studied how herring gulls behave in front person eating snacks on Brighton beachfront, UK. They gave the gulls the choice between two differently coloured potato chips,  and when the human were eating potatos chips from one color, seagulls approached the food, and chose the same colour that the experimenter was eating, the 95 per cent of the time.

Seagulls were able to use human cues for stimulus enhancement and foraging decisions. Given the relatively recent history of urbanization in herring gulls, this cross-species social information transfer could be a by-product of the cognitive flexibility inherent in species who steal food, called kleptoparasitic species. This success in urban environments is suggested to result from behavioural flexibility, which is likely to require specific cognitive adaptations. In food-stealing birds, success is said to reflect an ability to integrate and use information about both the environment and other individuals, and kleptoparasites generally have usually larger relative brain sizes than their hosts.

Do you like birds more, or do you prefer fish? It doesn't have to be pet related! You could just pick one you'd rather geek out on!

I've been more busy than I thought lately and made lots of new stuff that I'm proud of! :D Thank you everyone for all your immense support, I wouldn't be able to do this without you!! https://artofmaquenda.etsy.com
