From Queensland's Department of Agriculture and Fisheries brochure Can I have a pet rabbit?, Why are pet rabbits illegal in Queensland? Rabbits are Australia's most destructive agricultural and environmental introduced animal pest, [...] Can I get a permit for a pet rabbit? A permit cannot be issued for keeping pet rabbits of any variety ...

I can't comment specifically on ducks, but I will quote the Official Statement on Bread from the Queen's Swan Marker (who has responsibility for swans in the UK): There has been a great deal of press coverage in recent months regarding the ‘Ban the Bread’ campaign which is confusing many members of the public who like to feed swans. Supporters of the ...

YES, there is some truth behind the "1 billion heartbeats " claim. And when I say "some" I mean the creator of the comic didn't just make it up out of thin air. While it's not literally true that all animals get 1 billion heartbeats before they die, a relation between metabolic rate (which is related to heart rate) and life span has been observed. San José ...

The answer is that spiders definitely can hurt you. While you may not be likely to be killed, spiders can absolutely hurt you, whether from a large one's bite (whether venomous or not) or from any venomous spider. Australia is probably the best case here, and while they have only had one death from spider bite in 40 years (from a redback bite) this is ...

The very next line of the quote you included, from the site you linked was: More info: http://bit.ly/XLKKXb That redirects you to a 2011 news article in Discovery.com called The Other Side of Otters, which includes a witness account: A weaned harbor seal pup was resting onshore when an untagged male sea otter approached it, grasped it with its teeth ...

I cannot speak to the viability of dying tusks, but it does appear that the photo cited in the question is a fake, as noted on the blog staintuskstostopelephantpoaching.wordpress.com. Here's the original photo for reference: This blog also houses what may be the original source of the proposal, with its first post dated Dec 29, 2012 Could we fight ...

To address the feeding of ducks: Ducks Unlimited Canada has this to say: I’VE HEARD THAT FEEDING DUCKS BREAD IS BAD. WHAT SHOULD I FEED THEM? DUC does not recommend feeding ducks. It increases the chances of negative human/wildlife encounters and can make them dependent on people for food. The Canadian Wildlife Federation has a similar ...

tl;dr- I haven't been able to actual evidence of the claim that consuming bread causes angel wing in ducks, and an expert claims that there isn't any. Apparently the main claim against feeding ducks bread is that it gives them angel wing. However, I'm not immediately finding any evidence for this on Google; most results appear to be unreferenced political ...

This is a new paper published in a peer reviewed journal. It will take time before it garners the positive or negative citations that are the real peer review. In the mean time, our best option is to rely on non-expert opinion to judge the quality of this evidence. The research that you have already done about the claim seems like half of an answer already. ...

No, this is not true. Not even for just India, as Indian cobra (Naja naja) has round pupils and subcaudal (tail) scales are divided. There is also no pit visible. It is venomous species of snake. This answer assumes, that author means venomous snakes instead of poisonous, as this is common mistake. Also, Wikipedia should have enough credibility for this ...

In short, we can assume that they do. There are two layers to this problem: whether crustaceans experience stimuli which could correspond to pain if those stimuli are effectively pain The second question is really hard to answer, and I would say, fundamentally philosophical. When does rubbing become scratching? So please bear in mind that I would find ...

It seems possible but unlikely Pig ejaculation certainly does last a long time relative to human ejaculation, and pig ejaculation is measured in minutes, not seconds. Boar semen is collected to artificially inseminate sows. I found various guides on collecting boar semen which contain estimates for how long one should expect ejaculation to last. Here is ...

We just need to look at sled dogs and do a little math. In 1986, Susan Butcher broke Rick Swenson’s record, set in 1981, by completing the 1049+ miles in 11 days. 1049/11 = 95 miles per day. This dwarfs a marathon, and marathon runners don't pull sleds. However, there are other races where we manage 71ish miles per day. This is for the Self-...

To get a littler closer to the horse's mouth -- the news article is about the Living Planet Report 2018 as published by the WWF (the wildlife people, not the wrestling people.) On page 7 of that report we have: The Living Planet Index also tracks the state of global biodiversity by measuring the population abundance of thousands of vertebrate species ...

Yes they do. In this article from 1985 by Jean-Pierre Sylvestre The same adult male, once more tried briefly to insert its erect penis into the blowhole of one of the juvenile male Orinoco dolphins swimming underneath it Also in an article at the Economist: (credit to endolith) Male Amazonian river dolphins, for example, penetrate the blowholes of ...

There is at least one organisation that dyes Rhino Tusks pink, although there are also plenty of doctored photographs of that too. The Rhino Rescue Project has a dye which, while harmless to the rhino, gives a very bad reaction to humans, including nausea and vomiting. The dye renders the horn useless for "medicine" and ornamental use because of this, but ...

There is nothing about bat evolution that is a threat to the theory of evolution. First, the part of the claim that speaks of "moth-like wings" is not what elongated digits would look like. They might look more like those of a tarsier: Source: http://tarsieruk.homestead.com/tarsier.html#anchor_113 Second, the claim that there is no incremental benefit in ...

The Sun piece is likely to be lifted form The Financial Times article written by Susanne Sternthal1 on January 16th, 2010. The FT article is well researched and, we assume, fact checked, citing Andrei Poyarkov (note the different transliteration) and Andrei Neuronov as primary sources. Both are published writers, and Poyarkov a respected scientist. Sternthal ...

Yes. As published in "Do Fish Fall from the Sky?"

There are several fish which are capable of achieving this: Mangrove killifish The mangrove killifish (Rivulus marmoratus), found among the mangroves in Florida, Latin American and Caribbean, is a strange fish indeed. For starters, this is the only vertebrate animal that is known to fertilize its own eggs. There are males and females, but most of these ...

In answer to the question if [what is depicted in linked video] was really possible in 1940? The answer is unequivocally YES - in fact quite a bit earlier. Reanimating a severed head was hypothesised in 1812, first attempted in 1857 and, for the most part, perfected in 1928-29. In 1812, French Physiologist Julian Jean Cesar Legallois hypothesised that a ...

There are at least two documented cases where turtles were found with constricting plastic rings around their midsection. One with a six-pack ring, another with a milk bottle safety seal ring: turtle deformed from six pack plastic Turtle Mae West There is no evidence that these are hoaxes, nor that some other process caused the deformity. It is reasonable ...

There are a few mentions (although a bit less than one would expect): 91:13 And the messenger of Allah said: It is the she-camel of Allah, so let her drink! [...] 7:73 And to (the tribe of) Thamud (We sent) their brother Salih. He said: O my people! Serve Allah. Ye have no other God save Him. A wonder from your Lord hath come unto you. Lo! this is the ...

Yes, they echo. There's plenty of information about it on the Internet. The idea of a sound that doesn't echo is theoretically dubious, but more importantly, several people have shown this through experiment. Both the following links explain not only that there is a echo, but also why it is hard to perceive: The University of Salford's Acoustics ...

No, this is not true. The Daphniidae only live for about 18.2 million heartbeats, which isn't even close to the (very loose) criteria of "within an order of magnitude". There are other species as well. All animals just do not have "around a billion" heartbeats. A good mammalian counter example is the North American black bear. Even when not hibernating ...

Short Answer As other have noted, it's not true under all conditions. For example, sled dogs can outrun people easily in cold weather (see DARPA studies). However, it sounds like the commentator was referring to the endurance running hypothesis, which says ancient humans were able to hunt down nearly any animal by outrunning it. The context is key, because ...

What is the claim? Are you asking about total biomass, biodiversity, regional populations, ...? Are you asking about specific areas / countries, or worldwide (which will be hard to exactly quantify)? Are you asking about whether we have wiped out at least 60%, or are you asking whether a ballpark figure of about 60% is plausible? And are insects exempt ...

No, and I consider this 11 page publication to be the most authoritative assessment of the matter. It covers all the topics you've raised, as well as assessing whether it was possible that elephants were once capable of jumping (they weren't). With respect to your mention of the "Elephant Jumping Festival" - that is false, and discussed at the end of page ...

This is a myth, because monkeys don't normally eat bananas in the wild. "The entire wild monkey-banana connection in fact is total fabrication," Katharine Milton, who has studied the diets of primates for decades, told Tech Insider. "The edible banana is a cultivated domesticated plant and fruit. Wild monkeys never encounter bananas at all ever unless ...

No, horses run faster and longer. When comparing marathon and endurance riding we get the following numbers : Human : 42,195km in 2:03:38, average speed of 20,5km/h (world record at 2011 Berlin Marathon) Human : 160km in 11:28:03, average speed of 14km/h (100miles ultramarathon world record) Horse : 160km in 6:21:12, average speed of 25,2 km/h (world ...
