Happy #walkaboutwednesday everyone!
This is Carcharias taurus.
But it is also known as the...
Sand Tiger Shark, Grey Nurse Shark, Spotted Ragged-tooth Shark, Ground Shark, or Dogfish Shark.
Native range is in the Pacific, Atlantic, Indian oceans and Mediterranean sea
Average depth of 60 meters, but can be from 2-191m deep into the water column. They like tropical and temperate waters around surfzones and rocky reefs. 🌊
They can range in weight from 50-300kg (or 110-660lbs), and 3.6-6m (11-19ft) in length. 🌊
Males outnumber females (2:1), and are promiscuous breeders. Both males and females on average are sexually mature around 7 years of age. 🌊
Shark pups take 6-9 months to develop in the uterus and can even eat their siblings in the womb! (Their teeth develop early!) The female usually has hundreds of eggs in her uterus, but they get eaten and usually only give birth to one or two pups. They are ovoviviparous -- eggs develop inside the female in each uterus; young hatch from the eggs and are retained in the uteri until they are fully developed and are birthed alive. 🌊
They technically have indeterminate growth and are thought to live longer than sharks in captivity (13-16 years in captivity, and 35 years in the wild). 🌊
These sharks are not aggressive and are more active at night. 🌊
Fun fact: They swallow air and hold it in their stomachs for buoyancy!
Grey Nurse Sharks help regulate the prey populations in the ocean. However... Humans and larger sharks are the only known predators... mostly from shark hunting, fishing, ghost nets, and persecution. 🌊
They currently have different status around the world. however, they are critically endangered in the Commonwealth Legislation (Australia), endangered in New South Wales and vulnerable in other parts of the world. ❌❌❌
