The whitetip reef shark (Triaenodon obesus) is a benign species of shark that is sleek and slender. They can be easily characterized by the white marks that are present on the tips of many of their fins, especially their first dorsal fin, second dorsal fin, and upper caudal fin.
These white tips are also the reason for their name. This shark is known to be quite a good swimmer that is well adjusted to the reef habitat that it inhabits.
Whitetip reef sharks are relatively small and are grayish-brown in color. They prefer to live in shallow waters with a coral reef habitat and caves and can often be seen swimming low at the bottom of the ocean during the daytime and hunting by night.
They do not need to swim constantly in order to help with their respiration, unlike other sharks. The whitetip shark is known to one of a few requiem sharks, so it does not generally show any sort of aggressive behavior towards humans.
The whitetip reef shark mainly populates many Indo-Pacific areas but it is known to be a Near Threatened species of shark as it is constantly hunted down by humans. Here are some interesting facts about the whitetip reef shark for you to read to find out more about the amazing world under the sea.

How do they reproduce?
Male whitetip reef sharks usually achieve sexual maturity when they grow to a length of 3.3 ft (1 m), whereas female whitetips are a tad bit bigger in size when they reach the age of maturity. Both sexes also usually have to reach around five years of age before they can breed.
Their breeding season is subject to change depending on their geographic region and this species is known to be placental viviparous which means that their pups are born after internal fertilization.
Fertilized embryos get all their nourishment from a yolk sac, yolk stalk, umbilical cord, and placenta.
Mother sharks have a gestation period of up to five months and completely nurture their infants during this time. They usually give birth to between one and five pups per litter, but they do not provide any parental support after the gestation period when the pups are born.
What is their conservation status?
The whitetip reef shark is a Near Threatened species of a shark as per the IUCN because of the ruthless hunting of the species for human consumption. The International Union for Conservation of Nature has listed this species as Vulnerable, due to the steady dwindling of their numbers in recent years.
This reduction in their population is due to an increase in unregulated fishing that takes place in their habitats.
It is also because of their restricted habitat, slow reproduction rate, and low dispersal that have altogether made it impossible for this species of shark to regain its numbers.
However, some measures have been taken to protect this benign species of sharks and they are beginning to have a small impact. Sadly, these sharks are also susceptible to poaching despite the measures taken to protect them because of their high demand in the fishing market.
