No, sharks have internal fertilization. Its probably a pretty rare event in their lives (females of many shark species only reproduce once every two to three years, though they likely mate several times per mating season).
Are sharks monogamous?
Its unusual for sharks to have a social group. Mating would be a solid reason for these close-knit groups, but sharks normally mate seasonally, and these groups remain constant throughout the year. Unless these are monogamous, committed sharks, it probably indicates that mating isnt the reason they stick together.
How do sharks choose a mate?
At the end of the biting phase, the male will bite the pectoral fin of the female and insert one of his claspers into the female. Other observations include apparent dances or acts of strength to attract mates, although these observations are rare.
Do sharks bite when they mate?
The sharks behave aggressively during mating, and afterwards the females deliberately avoid the males. Dr Domeier added: “Male sharks bite the head, flank or pectoral fin of females during the mating ritual, but certainly these sharks are biting each other out of aggression as well.
Can sharks change gender?
Over a lifetime, in fact, sharks may go through thousands of teeth. Other scientists believe that the big sharks, like some other species, change sex when they reach a certain size: males become females. The switch may ensure survival by allowing the largest, most experienced sharks to give birth to young.
Why do female sharks have scars from mating?
On rare occasions, during mating season among sharks, mating scars appear on female sharks bodies caused by the males holding onto them. These scars are mostly deeper cuts and punctures, indicating a more forceful motivation such as coercive mating from the males side.
What is the danger disadvantage to male sharks when mating?
It appears that while the male shark holds onto a female in this way, it sometimes creates wounds known as mating scars (Fig. 1). These wounds reflect at least subcutaneous skin penetrations, but can be more severe, and can even result in permanent body damage, such as sliced pectoral fin edges (Fig. 2).
What is shark attracted to?
Yellow, white, and silver seem to attract sharks. Many divers think that clothing, fins, and tanks should be painted in dull colors to avoid shark attacks. Blood: Though blood itself may not attract sharks, its presence combined with other unusual factors will excite the animals and make them more prone to attack.
