Even though mermaids are warm-blooded, their tails are still cold-blooded. Their tails need moisture regularly to maintain integrity (just like fish tails do), especially the scales.
Warm blooded. They're obviously mammals as they have very prominent breasts and have their tail fins spread side to side (like whales, dolphins, and manatees) rather than fish and sharks who have theirs up and down.
The opah is the only known fully warm-blooded fish that circulates heated blood throughout its body. The opah, the only known fully warm-blooded fish, is a valuable species for commercial and recreational fishermen. However, researchers do not have a full understanding of the basic biology and ecology of this species.
A mermaid is a fabled marine creature with the head and upper body of a woman and the tail of a fish. In European folklore, mermaids were natural beings who, like fairies, had magical and prophetic powers.
A mermaid is a mythical sea-dwelling creature, often described as having the head and body of a woman and a fish's tail below the waist. Stories of mermaids have existed for thousands of years and span cultures across the world - from coastal settlements in Ireland to the landlocked Karoo desert in South Africa.
A male mermaid is called a merman. Aquatic mammals that suckle their young in human fashion above water—such as the dugong and manatee—are considered by some to be the origin of these legends.
Centuries ago manatees were mistaken for mermaids, the half-woman/half-fish creature of myth and legend. The confusion may seem absurd now, but back then little was known of the sea beasts that lived in the ocean (much of the ocean is still unexplored today).
How are mermaids born? Once again, assuming mermaids reproduce the way fish do, mermaid babies would be born by hatching from eggs. Though it is possible for mermaids to get pregnant and give live birth like dolphins.
Taxonomic specialists once thought manatees were closely related to walruses based on facial similarities, but studies using biochemical analysis of proteins have demonstrated that the closest modern relatives of sirenians are elephants, aardvarks, and small mammals known as hyraxes.
What did Columbus see off the coast of Africa? On 9 January 1493, Christopher Columbus observed something remarkable off the coast of Africa... mermaids. In his journal he described the encounter with three mermaids that elevated themselves above the suface of the sea.
Note: Hummingbird has the highest body temperature i.e. 107°. Elephants and whales belong to mammals that have body temperature ranging from 97° to 103°. Monkeys being closely related to humans have body temperature ranging from 98.6° to 103.1°.
The icefish
The Antarctic icefish live in water colder than freezing — 2 degrees below zero Centigrade. Ocean water doesn't freeze at this temperature because it's full of salt.
Extreme changes in environmental temperatures can be fatal to the cold-blooded animal. As water temperatures increase, oxygen content is reduced. Raising the temperature from 41° F to 95° F will cut the oxygen level in half.
Some Sirens are benevolent and have been known to rescue drowning humans, while others are monstrous and are able to sink entire ships. Sometimes a Siren will fall in love with a human.
'Mermaid' and 'siren' are often used interchangeably, but there is actually a distinction between the two, according to legend and literature. Mermaids are half fish, half women who live in the ocean and are typically harmless. Sirens are like evil mermaids.
The siren was depicted as a half-woman and half-fish mermaid in the 9th century Berne Physiologus, as an early example, but continued to be illustrated with both bird-like parts (wings, clawed feet) and fish-like tail.
The Japanese ningyo (人魚, literally "human-fish") has been glossed in a noted dictionary (Kojien) as a "fabulous creature" which is "half woman, half fish", later revised to "half human (usually woman) and half fish". Hence the term ningyo includes not just the mermaid but the merman also.
Kelpie. Kelpies is a rare form of Mermaid found in Scottland which can be found in a mixture of fresh and salt water. They are aquatic shapeshifters and can only look semi-human when in their mermaid form.
The female oceanids, nereids and naiads are mythical water nymphs or deities, although not depicted with fish tails. "Nereid" and "nymph" have also been applied to actual mermaid-like marine creatures purported to exist, from Pliny (cf. §Roman Lusitania and Gaul) and onwards.
The oceans are far from a safe place, though. Considering the threats of fishing, poaching, environmental pollution, predators and other factors we estimate an average mermaid life to last a few centuries at most. (Of course there are notable exceptions such as Serra Macrourida, who lives for one reproductive cycle.)
Most babies with mermaid syndrome do not survive, living a few days at most. There have been a few cases of surgical separation of the legs. A team of doctors from different specialties will help plan and provide the treatment and care of babies with mermaid syndrome, as well as supporting the family.
During a mermaid birth, the baby is delivered in a wrapped in a soft bubble, making it look like a gift wrapping. It is also called veiled birth or en caul birth. As per several experts, this kind of birth takes place only in one in 80,000 times.
On January 9, 1493, explorer Christopher Columbus, sailing near what is now the Dominican Republic, sees three “mermaids”—in reality manatees—and describes them as “not half as beautiful as they are painted.” Six months earlier, Columbus (1451-1506) set off from Spain across the Atlantic Ocean with the Nina, Pinta and ...
No evidence of aquatic humanoids has ever been found.
Mermaids — those half-human, half-fish sirens of the sea — are legendary sea creatures chronicled in maritime cultures since time immemorial.
