The common name Tubarão Serra represents some species of the Pristiophoridae family that can be seen in different regions of the world.
|Serra Shark: Weird Species Also Known As Serra Fish|
In addition, fish have good hunting strategies, precisely because of their body characteristics.
Therefore, today we will offer you more information about the species, distribution and curiosities.
- Scientific name – Pliotrema warreni, Pristiophorus cirratus, P. japonicus, P. peroniensis, P. nudipinnis and P. schroederi.
- Family – Pristiophoridae.
Serra Shark species and main characteristics
The Serra Sharks have similar characteristics of an elongated upper jaw in a long narrow blade.
Thus, the teeth are alternately large and become small on the sides.
On the other hand, the snout has two long barbels and extends to support the teeth at the margin.
This makes the animal look like a chainsaw.
The fish also have two dorsal fins and no anal fins.
Finally, individuals reach 170 cm in total length.
best known species
The main species of Serra Shark would be the Pliotrema warreni that inhabits the subtropical waters of the western Indian Ocean, which have a temperature between 23° and 37°C.
As differentials, we must mention that the species has a saw on the snout and six pairs of gill slits.
Its coloration is close to light brown on the back and the belly has a light color.
The species was cataloged in 1906 and prefers to inhabit waters between 60 and 430 m deep.
This species is on the IUCN Red List, which means it suffers from some extinction threats.
Finally, it does not offer any type of risk to human beings, given that its habitat would be deep.
species of the same order
There are 5 species of Shark Serra that belong to the same order, Pristiophoriformes.
Thus, we will deal specifically with each one below:
Firstly, Pristiophorus cirratus represents a species that lives in the eastern Indian Ocean, particularly around Australia.
The fish stay on continental shelves with a depth between 40 and 310 m.
Also, the shark was listed in 1794.
We should also talk about Pristiophorus japonicus that is present in the northwest of the Pacific Ocean, around countries such as northern China, Korea and Japan.
The species was cataloged in the year 1870 and prefers to inhabit the bottom of the oceans at a depth of up to 500 m.
Pristiophorus peroniensis is located in Eastern Australia and its natural habitat would be the open sea.
An important point about the species is that the description in 2008 was “Pristiophorus sp”, but now it has gained its scientific name, which means that there is little information.
It is even considered a relative of “P. cirratus”.
By the way, meet Pristiophorus nudipinnis that also inhabits the eastern coast of Australia in places with depth between 37 and 165 m.
Being cataloged in 1870, this animal reaches up to 1.2 m and is also commonly known as southern saw shark or short saw shark.
Regarding coloration, the dorsal region is slate gray and the body of the fish has some marks.
The ventral side has a pale cream or white color and individuals live up to 9 years of age.
Finally, there is the Pristiophorus schroederi which is found in the Central Atlantic Ocean in Cuba and the Bahamas.
A very interesting point would be the depth that the species can reach, about 1,000 m, in addition to measuring 80 cm in total length.
Reproduction of the Serra Shark
The Serra Shark becomes sexually mature when it is male, reaching almost 1 m in total length.
Females are mature between the first and second year of life, and they can give birth to 3 to 22 offspring.
Also, the average number of offspring would be around 10 and gestation lasts 1 year, considering that the small fish inhabit the shallow coastal regions.
Pups are also born with a total length of 27 to 37 cm.
But, know that the reproduction process and the stage in which the fish becomes mature are information that can vary according to the species.
The Serra Shark eats bony fish, squid, shrimp and other crustaceans.
In this way, the animal uses the saw for its hunting strategies.
That is, the saw serves to kill and stun its victims at the time of attack.
Another functionality would be to drill holes in the sandy bottom to capture small invertebrates.
The main curiosity about the Tubarão Serra would be its importance in trade.
As with other shark species, fins are used to make aphrodisiac soups throughout Asia.
Where to find the Serra Shark
The Shark Serra is present in the waters of the Indo-Pacific, so we can include regions from South Africa to Australia and Japan.
As a result, individuals inhabit shallow and coastal waters, which have a depth of up to 100 m, something that again depends on the species.
The fish also have the ability to tolerate a wide range of salinities and swim in freshwater, marine or estuarine habitats.
