The probable predators of this species are larger sharks. Research from 2002 showed that although juvenile sevengill sharks utilize nursery areas in a similar way, males mature faster than females even if they are the same size and thus males are more likely to leave the nursery area before females.

Subcarangiform, Carangiform, Thunniform: These swimmers undulate the posterior half of their body and are much faster than anguilliform swimmers. At any point while they are swimming, a wavelength <1 can be seen in the undulation pattern of the body. Some Carangiform swimmers include nurse sharks, bamboo sharks, and reef sharks.
Bullhead sharks have tapered bodies, with most species reaching around 70–130 centimetres (2.3–4.3 ft) in length. Their bodies vary in colour, including shades of grey, brown, and red and pale colours, and are covered in a variety of patterns, including spots and stripes. [2]
The researchers will also have an eye out for more soupfins, hoping to confirm a larger-scale presence in the south Sound. As they continue to tag sharks, the researchers will record sharks ...
Ever since the movie "Jaws" popularized great white sharks as predatory man-killers, people have had misconceptions about these animals. That is why researchers have been doing everything they can ...
Swell sharks hunt at night for bony fish, molluscs, and crustaceans. [2] [3] They will eat prey that is dead or alive. [3] They feed either by sucking prey into their mouth or by waiting motionless on the sea floor with their mouth open, waiting to encounter prey. [2] [4] Swell sharks have also been known to look for food in lobster traps. [2]
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
Smaller sharks eat proportionately more cephalopods and crustaceans, switching to fish as they grow older. [ 10 ] [ 16 ] Many predators feed on the milk shark, including larger sharks such as the blacktip shark ( Carcharhinus limbatus ) and Australian blacktip shark ( Carcharhinus tilstoni ), and possibly also marine mammals .
