egg laying mammal


The full set at last! 

These days everyone’s all about sparkly vampires and tyrannical dictatorships trying to make you get with cute boys, and I’m just over here with my 90s YA heroine, who hangs out with marmosets and egg-laying mammals and rides dinosaur skeletons over tyrannical dictatorships before breakfast. 

I really wanted to stick a tubby little duck-billed platypus into the final cover - and I still might. Don’t tempt me!


  • southaustraliaSo… this is how echidnas roll in Adelaide! When you’re built like a big, round pin cushion you can expect to take the odd tumble or two - especially when your mates give you a helping hand! Neil Edwards stumbled across this parade of echidnas on a photo mission in the Onkaparinga Hills. While he was busy training his lens on birds and kangaroos, he spotted a little movement as he was packing up for home - and what happened next clearly made his day! These shy monotremes (egg laying mammals) are pretty common around these parts, and right now it’s mating season so they’re more active during the day. If you’re out and about, keep your eyes peeled for ‘echidna trains’ – where one female is followed by up to 10 males at a time! That’s apparently what’s happening here… and good luck to the young lady! #SeeSouthAustralia [📍Location: just a 2 hr flight from Sydney to #Adelaidein #SouthAustralia ]


Echidnas, sometimes known as spiny anteaters, belong to the family Tachyglossidae in the monotreme order of egg-laying mammals. The four extant species, together with the platypus, are the only surviving members of the order Monotremata and are the only living mammals that lay eggs. Echidnas live in Australia and New Guinea. Echidnas evidently evolved between 20 and 50 million years ago, descending from a platypus-like monotreme. This ancestor was aquatic, but echidnas adapted to life on land. The echidnas are named after Echidna, a creature from Greek mythology who was half-woman, half-snake, as the animal was perceived to have qualities of both mammals and reptiles.

When European Naturalists in the 18th Century started hearing claims about a venomous, egg-laying mammal with the bill of a duck and the tail of a beaver living in Eastern Australia, they all cried hoax.

Even when presented with a corpse, scientists were hesitant to acknowledge this creature as genuine. In fact it was a few decades after the initial descriptions of a corpse that the Platypus was finally officially recognised by the scientific community.

More Mammals with Venom

by John Wible

The duck-billed platypus, Ornithorhynchus anatinus, is no doubt one of the world’s oddest mammals, with a suite of adaptations to its life in streams in eastern Australia and Tasmania. Its suede-like bill is packed with electro- and mechanoreceptors, which help the platypus find small invertebrates and fish in murky waters. It has webbed forefeet and hind feet and a hairy, beaver-shaped tail, all great for swimming and diving, and a lush, thick coat for insulation on cold mornings.

As with other mammals, the female platypus produces milk to nurture its young. However, its young are hatched from leathery eggs! Along with the echidna or spiny anteater from Australia and New Guinea, the platypus is one of the two types of living monotremes or egg-laying mammals. This is in contrast to the other groups of extant mammals, marsupials, and placentals, which have live births.

Along with egg-laying, the skeleton of the platypus is a throwback to its mammal-like reptile origin. The bones in its arms and legs, the humerus and femur, are set perpendicular to the trunk, giving the platypus a sprawling posture and a waddling gait on land. Marsupials and placentals have more upright postures with less waddling.

But where is the venom? If you look closely at the ankle of the male platypus, you will see a deadly looking weapon made of keratin, just like your fingernails. This tarsal spur sticks out from the body and sits on a small, flat bone—the os calcaris. The spur is hollow and connected to a gland below the knee that produces venom during the platypus breeding season. Because of this seasonal activity, the venom is thought to be used in male-male competition for females. 

For humans that make the mistake of picking up male platypuses at the wrong time of year, the venom is not deadly, but it is excruciatingly painful. One unfortunate soldier said it is worse than shrapnel! A small remnant of the spur is retained in juvenile female platypuses for only a few months after hatching, and the supporting bone, the os calcaris, without a spur occurs in the echidna. In recent years, tarsal spurs and support bones have been found in the fossil record for numerous groups of extinct primitive mammals that lived during the Age of Dinosaurs. Rather than being unique to the male platypus, venom manufactured in the leg may have been a widespread component of early mammalian weaponry for survival in the hostile Mesozoic landscape. Why this apparatus was lost in early marsupials and placentals is a mystery. One group, the bats, have reinvented a tarsal spur, where it is used in support of the wing membrane.

John Wible, PhD, is the curator of the Section of Mammals at Carnegie Museum of Natural History. John’s research is focused on the tree of life of mammals, understanding the evolutionary relationships between living and extinct taxa, and how the mammalian fauna on Earth got to be the way it is today. He uses his expertise on the anatomy of living mammals to reconstruct the lifeways of extinct mammals. John lives with his wife and two sons in a house full of cats and rabbits in Ross Township.

many people are aware that the platypus is one of only two egg-laying mammals and is furthermore the only poisonous mammal but did you know that they also don’t have stomachs

they did once, but they stopped needing to use them and at some point the whole chunk of DNA that codes for a stomach just mutated straight out of their genetic code

also a baby platypus is called a puggle

anonymous asked:

The only reason Tsukki likes dinosaurs is because once when they were younger yams made some off hand comment about how cool they were and Tsukki wanted to seduce -ahem- impress him with his Dino knowledge.🌸

he checked out a book from the library and just memorized every single fact he could and rattled them off the next day and yamaguchi just goes “YOU KNOW WHAT’S COOL NOW? EGG-LAYING MAMMALS”

The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth. The animal is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record. The first preserved platypus body was thought to have been a fake, made of several animals sewn together, when it was first looked at by scientists in 1799.

The unusual appearance of this egg-laying, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate hoax. It is one of the few species of venomous mammals: the male platypus has a spur on the hind foot that delivers a venomcapable of causing severe pain to humans. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognisable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of its 20-cent coin. The platypus is the animal emblem of the state of New South Wales.

Among humans, it is not known when the enterprising citizens of the Invisible Empire began their work on the Tiny Taxonomy—indeed, its origins are disputed even among renowned historians of the Empire—but in the millennia since its first recorded appearance, the Invisible Empire’s Tiny Taxonomy has become an authoritative and invaluable resource on the categorization of the natural world. Encompassing over 102 volumes, the Taxonomy classifies the multitudinous plants, shells, egg-laying mammals, mushrooms that may be used to poison a man, moths, &c. in a system so simple and inspired that no one (human or invisible) has yet been able to match it in accuracy, comprehensiveness, or elegance.
The fourth volume of the Tiny Taxonomy of Plants, “Flowers,” stands only 1-inch high (an appropriately oversize volume for the average citizen of the Empire) with perforated paper pages embedded with seeds. When planted, each page sprouts into seven varieties of wildflower.
Not all volumes of the Tiny Taxonomy are made of paper, however. The Tiny Taxonomy of Rocks and Minerals, Volume VII: Crystals, for example, is carved onto wafer-thin tablets of variegated gemstone, while one volume of the Tiny Taxonomy of Insects has covers made from the scintillating elytra of various species of beetle.
Copies of the Tiny Taxonomy are easily accessible through the Invisible Empire’s vast libraries, which are often nestled inside hollowed-out trees and the abandoned burrows of wild rabbits. Plant enthusiasts might spend hours poring over the Taxonomy’s tomes, curled up in reading galleries inside the trunks of towering redwoods or ancient gnarled oaks, while eager botany students might make miniature notes by the light of an obliging glow worm or bioluminescent fungi.
For those humans who would otherwise never have the opportunity to study the arcane classification systems of the Invisible Empire, the full text of The Invisible Empire’s Tiny Taxonomy of Plants, Volume IV: Flowers is reproduced, with the consent and good will of the Invisible Empire’s Most Illustrious Academy of Sciences, here:
1) houses of spirits and sprites
2) resplendent
3) poisonous
4) fuzzy catkins
5) ineffable
6) whose fragrance lures the dead from their graves at night
7) that fall from maidens’ mouths
8) lining the paths of lovers who will never meet again
9) many
10) ground with the internal organs of jaguars as a potion against fear
11) at the center of the moon
12) listed in books
13) having recently emerged from the coffee-colored loam
14) that bloom only once every three thousand years

THE INVISIBLE EMPIRE’S TINY TAXONOMY OF PLANTS, VOLUME IV: FLOWERS is inspired both by the ancient and/or fictitious “Celestial Emporium of Benevolent Knowledge,” cited by Jorge Luis Borges in his essay, “The Analytical Language of John Wilkins,” and by the pin-sized books of Evan Lorenzen.

Say something interesting.

Echidnas /ᵻˈkɪdnə/, sometimes known as spiny anteaters,[1] belong to the family Tachyglossidae in the monotreme order of egg-laying mammals. The four extant species, together with the platypus, are the only surviving members of the order Monotremata and are the only living mammals that lay eggs.[2] The diet of some species consists of ants and termites, but they are not closely related to the true anteatersof the Americas. Echidnas live in Australia and New Guinea.

Echidnas evidently evolved between 20 and 50 million years ago, descending from a platypus-like monotreme.[3] This ancestor was aquatic, but echidnas adapted to life on land.[3]

Phineas and Ferb 10th Anniversary - 104 Memories of Summer: #3

The Flynn-Fletcher’s Pixel Backyard by @rewa14

Although I was not part of the many who watched Phineas and Ferb when it first came out I was hooked on it after watching It’s a Mud, Mud, Mud, Mud World. Since then P&F has been a huge part of my life, with me even making a club, P.E. (Platypus Education), at my elementary school based around the titular semi-aquatic, egg-laying mammal of action. Anyway, thank you Phineas and Ferb for what you brought to my and so many other’s lives!

megazaprat  asked:

so, wait , if you think galra are furry space lizards, are you posting they are some sort of space equivalent of the platypus or monotremes in general? being a sort of in between? Do you think Galra lay eggs?

> No to the first because monotremes are mammals, just egg-laying mammals. I feel like just like pangolins are weird mammals that have figured out how to scale, galra are like. weird reptiles that have found out how to fur. Though on specimens like Zarkon or first episode captain I imagine it’s short and more velvet-textured than say, Sendak’s. (so just consider the idea that by my headcanon, Zarkon is actually super soft. To touch, I mean. Personality-wise he’s still a huge jerk.)

Fur may have been a development on their planet to improve heat retention because the galra planet as Shiro sees it seems very dark- if not a lot of sunlight gets to it, fitting the perpetually twilit “Planet Doom” we see in DotU/GoLion and Force, it’d make sense local life would probably do what it could to make the most of staying warm.

> Yes I think galra come from eggs. It’s kind of an irrelevant headcanon because I’m pretty sure for obvious reasons we’re not exactly going to see The Miracle Of Life happening onscreen. I mean, if they did really want to show us a particular character’s birth, showing someone hatching out of an egg is a lot more likely for a Y7/PG show than live birth. At this point I’m not sure what, narratively, they would gain, but.  ¯\_(ツ)_/¯
