Wild turkey It also feeds on a lot of other small species. This creature is a very good swimmer and also preys on small fishes.
M October 30, blubber constipation extinction Guest Post hair hypothermia lies mermaid This guest post is brought to you by Sheanna Steingass. She is also author of Oregonbeachcomber. And they admit that.
And who can blame them? People love mermaids, they delivered, and they made a ton of money. Here are 5 reasons. It takes waters much above 70 degrees to maintain an individual especially a lean one for a prolonged period of time in the water without dying.
They would freeze to death. Quickly, and matter what ocean. The truth is, the human-like body form is not made for surviving long periods in the water.
Assuming mermaids would want to live out in the bottom of the open ocean, it is just too cold for them. And, once you get down a few meters, water temperature drops dramatically. Oceanic water temperature drops quickly below the surface- no matter what climate.
The first option would to look like a marine mammals, whose thick blubber layers protect them from cold, dark waters. What of smaller animals? The sea otter has more thanhairs per square inch Kuhn et al.
Otters have to groom themselves often to keep their hair filled with air, and not with water Fish et al. Very inconvenient if you are an elusive denizen of the deep.
And those long slender arms? They would freeze off. Marine mammals have fusiform bodies reducing surface area-to- volume ratio and short appendages that can withstand reduced bloodflow and heat.
So, essentially, you would end up with a very hairy or obese mermaid with stubby arms. Mammals are defined by being warm-blooded and having hair; fish do not.
The human line of evolution is fairly well-mapped. Prior to the development of hominids, humans and fish are so far branching down the evolutionary tree that the first marsupial mammals appeared during the Jurassic period million years ago Kumar and Hedges Additionally, the idea that somehow a human bred with a fish and produced viable, virile offspring is just ridiculous.
Which brings us to the next point… [Megazostrodon photo] No mermaids here! They would go extinct. How do mermaids reproduce? They are human down to the waist, after all. Well, there are two options for that.
First, they could do it human-style. But what if you have fish parts down there? Most fish reproduce externally- with females depositing eggs in the environment and males fertilizing them. Could mermaids lay eggs? The only mammals that produce eggs are the echidna and platypus- the monotremes of the class Mammalia.
As far as I can tell, there are waaaay more mermaids than mermen. They would be constipated. Mammals digest food via complex digestive tracts, which produce solid waste and urine- a sterile byproduct composed mostly of water and waste, salts, and proteins.
Fish kidneys produce ammonia- which is expelled via their gills. Yep, they essentially pee through their gills. Even more tellingly- can you point out the butt on a mermaid? We have no physical evidence.Dolphin Research Paper.
Topics: Marine mammal park, Dolphins in Captivity Introduction Most people are fascinated with dolphins and crave to see them in Sea World, or another aquarium, and even enjoy seeing them perform in shows.
However, most people do not think about the harm that dolphins go through in order for the . Jaguarundi is a medium sized wild cat, which belongs to the Felidae family.
It is slightly larger than the common house cats. Sometime the Jaguarundi is mistaken with an otter or weasel.
Anatomy and morphology. Baiji were thought to breed in the first half of the year, the peak calving season being from February to April. A 30% pregnancy rate was observed. Gestation would last 10–11 months, delivering one calf at a time; the interbirth interval was 2 years. Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years.
We have now placed Twitpic in an archived state. Oct 10, · Scientists have simulated marine mammal sex using actual reproductive organs collected from corpses to understand the evolution of their genitals. This post is in Part One of our series on Dolphins and Us - their intelligence, culture and society, and why it's time to bring an end to keeping them in captivity.
