Would be like a fox to speak in glib riddles while looking at you with a vaguely smug expression.

It's the fox of wisdom. I would like to ask it its wisdom. well *this* fox says, "when you have tried everything, and nothing works, you know your next move." That's a good wisdom!

We're all about dolphins this week, I don't know if anyone requested this but if you did please bring your ticket to the claims booth.
Dolphins are another huge grouping of animals under the Cetacea infraorder though what is and isn't a dolphin is a bit hinky, the fact that a number of whales are included in the classification shows how weird it can be. Focus though for this week's facts are on the insanely happy common bottlenose dolphin. The common bottlenose dolphin has a huge range, where there's temperate waters you'll find them. The location of a given pod can also determine size, generally a bottlenose will be around 2 metres long in warmer waters but the closer to the poles the larger they can be, some upto 4 metres long. On average, an adult will be 2.5 metres long and weigh between 200-300kg. Bottlenoses are renowned for having the largest brain to body mass ratio (humans coming in first) among mammals and their high intelligence though of course big brains don't make for smart animals. Such an example is their cognition and self-awareness. Their diets consists of a lot of fish, squid and crustaceans, either in a group when dealing with shoals or alone for any bottom dwellers. You may think those teeth (not seen here: those teeth, see above fact) are for tearing and ripping but not so, their teeth are not used for feeding but for gripping onto food. There is no nose on a bottlenose or any cetacean, most will breathe through their blowhole. What they do use their snout for is concussing fish and flipping them out of the water to feed on, a process called "fish whacking". Socially, they live within communities much like our own, sometimes pairing off to join other groups though males will live in groups of three with females living in groups of 10-15. Some of these groups can be very large, sometimes upto 100 with one recorded at over 1,000 members. Dolphins have a pretty sweet lifespan, some living upwards of 40 years and others still making good with 20. They also have an interesting habit of blowing air rings and often play games with other dolphins using them. Finally, common bottlenose dolphins aren't endangered though are still threatened by human interaction. Even with that, they're commonly found co-operating with human fishing vessels by pushing out fish to the nets while they get to eat any fish which escape.
Photogenic fishmammal action, go!

I find these animals wholly unappealing, but nice writeup, hippo.
Also, once the weather warms up, I'm changing my status from "fleecy" to "hinky" or possibly "hinkety".

Hinkety isn't a word though hinky is, what happened with nubbin? I liked nubbin. I like nubbin too! Nubbin is the best, but it's not an adjective. I'm trying to limit my status to adjectives or adverbs. "Hinkety" may not be a proper word, but it's an old-fashioned bit of nonsense that's fun to say.

The fossil history of whales in general is an interesting one, as their ancestors were terrestrial mammals that adapted to go back into the sea and out sea-go the sea-going critters that still lived there. The lineage includes some of the best examples of gradual evolution, and "transitional" forms, which are of course denied by those who insist there are no transitional fossils.
The whale group's marine journey starts about 50 million years ago, and dolphin-like critters with evidence of using echolocation start showing up about 30 million years ago. Some of these are quite interesting, including families of dolphins with long, toothless bills like a swordfish.
The bottlenosed dolphin (Tursiops) shows up about 5 million years ago, and appears to have developed in the Mediterranean region. Since then they have populated the Atlantic and Pacific oceans. Some workers split the Atlantic and Pacific populations into separate species, but even the lumpers agree that there are significant physical, biochemical, and even cultural differences between the two groups.
Tursio is Latin for dolphin, and the genus name Tursiops means "looks like a dolphin". They can't just use the name Tursio because some early taxonomist used the name to describe the sperm whale (Physeter), and by the rules of zoological nomenclature, that name has priority and can't be used to describe a different critter.

Wow, sorry I didn't reply sooner, swear I did reply at the time. You can request one of course and I'll try and fit it in, should be sooner than later if I move some stuff about.

This week's bird is a non-flightless one again as we cover the Emperor Penguin as requested by Lord Lucan !
Part of the large Spheniscidae family is Aptenodytes forsteri or the Emperor penguin to you and me. Standing as the largest of the penguins it is the most penguiny of the penguins, even more than the little blue penguin, endemic to the south coasts of New Zealand and Australia. The emperor penguins are classed as Near Threatened, mostly due to receding ice. Their weight is highly variable going down to 23kg during breeding periods and around 35kg on average when feeding going upto 45kg. They stand at just over a metre tall with females being on average more heavy than the males though by very little. Out in the cold of the Antarctic, temperatures can be as low as -40º with strong winds and cold waters but don't worry, penguins have feathers and lots of them. Having been adapted for the cold, the majority of their insulation comes from their dense plumage along with a thick layer of fat. Though birds, penguins cannot fly as they're not equipped with wings but flippers. These are powerful allowing for far more grace underwater than on land though on land they still get around by waddling or sledding on their stomachs. Emperor penguins are reliant on marine life like most aquatic animals for their food, consuming mostly fish but taking in small cephalopods and small crustaceans like krill. They dive deep to feed, going down regularly to depths of 150m with deeper dives to 500m to bottom feed. The lives of the emperor pengiins are dominated by the long periods of having to incubate their eggs. They only lay one at a time and is cared by the father while the mother goes off for two months to forage. At the end of this two months of no food, the father is freed to go forage for two months and this continues in a cycle with each going off to feed until the chick is ready to fledge and endure the march of the penguins. It's a crappy life being an emperor penguin. As survival chances are low, penguins have to be social, often coming together in groups in order to breed and protect their offspring with unique calls so they can be identified in crowds of several thousand birds which all look alike. There is only a 19% chance of survival past the first year due to the cold but if they make it past that they'll live for 20 years, maybe more. To finish up, while emperor penguins are strong underwater they're also very strong on land too. Apparently during an expedition to capture a male penguin, a team of six were unable to capture it because of how forceful the penguin was and it required all six working at once to capture it.
Wenk!

Only a 19% chance of survival past the first year? Can't we build them houses?! I wonder how they decide what adults have to stand on the outer ring of their groups with their backs to the wind. There was a story yesterday about 150,000 Adélie penguins being wiped out by being blocked by an iceberg or something, but others say they're fine. www.cbc.ca/news/technology/adelie-penguins-1.3450705

Well, at least I learned that penguin carcasses don't rot.
They decide on pecking order by drawing straw lots, shortest gets thrust to the outer rim of Hoth.

Having avoided the penguin documentary fad a few years ago, I don't think I realized until right now how effin' adorable baby penguins are. I'm late to the party, but AWWWWWWWWWWWWWWW!!!!!!! And they have a less-than-20% chance of survival? I want to give them all adorable little tiny parkas or sweaters! But then I'll take the parkas/sweaters away when they reach that awkward, ugly teenage bird phase. They have to learn that if they can't be cute, tiny and fluffy or cute, enormous and in formalwear, they're on their own.

I'm given to understand that there will be no installment this week, but that the series will resume next week by answering the question we've all be asking ourselves - 'Marmots: What is their deal?'.

Though it just misses out on the theme, I think we could squeeze in my idea for a band: Manatees on Safari. I had even made a rudimentary album cover

We can use recordings of their mating calls as samples to run through synthesizers. It'll draw a lot of people living things to shows!
