  • As of 2016 it was estimated that there were no more than 250 individual daggernose sharks, due to their limited range and as slow-reproducers they are listed as Critically Endangered.

  • Females live to around 20 years old whereas males live to 12 years.

  • Daggernose sharks grow to up to 5 feet in length and can be identified by their long, prominent snout.

  • The biggest threat to these sharks are unregulated artisanal fisheries. They are the victim of bycatch in artisanal gillnets designed for Spanish mackerel and king weakfish.

Sand Tiger Shark

  • Sand tiger sharks are also known as gray nurse sharks and they may look ferocious but they aren't all that dangerous, they are a docile and non-aggressive. 

  • These sharks live for around 15 years, growing to between 6.5 feet and 10.5 feet and recognised by their distinct oblong tail with a notched upper lobe. 

  • Of all the shark species they have one of the lowest reproduction rates. In some regions of the world they are considered critically endangered but as a species overall they are listed as vulnerable.

  • They are the only known shark to control their natural buoyancy by gulping up air from the surface and holding it in their stomachs allowing them to hoover motionlessly in the water.

Sawback Angelshark

  • The females grow up to 6 feet with males slightly small growing up to 5 feet. In appearance they are similar to rays or skates and can be distinguished from other angelsharks by its row of dorsal spines. 

  • These are ambush predators, they lurk on the seafloor and wait for their prey to pass by in the water above them before they attack.

  • The main threat to these sharks is commercial fisheries, their decline over the last few decades has been attributed to trawler activities in the northeast Atlantic and Mediterranean. They are greatly affected by trawlers because they are bottom dwelling fish.

Pondicherry Shark

  • The last confirmed sighting of pondicherry sharks was in India in 1979, though in 2019 a specimen was found in Sri Lanka that is thought to be one though we are waiting for confirmation.

  • They grow no longer than 3 ft and are described as "short and stocky" with a long pointed snout and large circular eyes. 

  • These sharks are thought to reside in the coastal water from India to the Gulf of Oman into Southeast Asia.

  • Pondicherry sharks are considered harmless to humans, and use to be caught for their meat. They are incredible rare and were at one time considered extinct.

Great Hammerhead Shark

  • The great hammerhead shark is the largest of all the hammerhead shark species, reaching a maximum length of 20 feet! 

  • Unlike the scalloped hammerhead shark the great hammerhead shark prefer to be alone and will migrate incredible distances, sometimes over 750 miles!

  • It is thought that they are cannibals and will eat their own kind when they need to.

  • Great hammerhead sharks have a high bycatch rate, combined with a low reproduction rate which has led to them being classed as critically endangered.
