There's a good reason why Mozambique is considered one of the world's top diving destinations. Its nutrient-rich waters support underwater life on a grand scale, including around 122 species of sharks, skates and rays. 

Silvertip sharks (Carcharhinus albimarginatus) are an aggressive species characterised by distinctive white tips and borders on all of the fins.

Silvertip sharks grow to a maximum length of three metres, which makes them a fair bit bigger than your average human diver. 

Many of Mozambique's shark species are being increasingly targeted by the fisheries industry due to growing Asian demand for shark fin. This demand, coupled with a lack of adequate regulation, poses a serious threat to their future survival here. 

Blacktip sharks (Carcharinus limbatus) are streamlined, agile hunters known for their spinning manoeuvres and leaps out of the water when targeting schools of fish. 

A ubiquitous little underwater companion, the remora fish attaches itself to bigger marine animals like sharks in order to gain protection, tasty leftovers and easy transport. 

It might look smooth to the touch, but a shark's skin is actually more like sandpaper. Covered by tiny tooth-like scales called denticles, it allows the animals to move more efficiently in the water. In fact, its amazing properties have inspired boat designers, swimsuit makers and, most recently, German airline Lufthansa.

We’ve been programmed to fear that torpedo shape and dreaded dorsal fin, but in fact, you’re more likely to be killed by a vending machine, a bolt of lightning or even someone’s pet pooch.

Known as countershading, this form of camouflage refers to the darker colouration on the upper (dorsal) side of the body and lighter colouration underneath. The effect? Disguise from all directions, whether looking up at the shark against the surface or looking down at it against the sea floor.

Sharks have a natural curiosity and will often circle and swim up close to investigate divers and their gear. In this Crazy Cameramen episode, one of the animals takes a 'special' interest in the camera housing. 

It might be top of its family hierarchy (the species usually dominates other requiem sharks of equal size), but even silvertips sometimes fall victim to shameless photobombers. 

Tiger shark diets are infamously varied – they're quite happy to feast on anything from crustaceans to turtles. Accommodating that sort of appetite is all about the right set of teeth. The tiger shark's serrated set is specialized for slicing through flesh, bone and other tough substances, including turtle shells.

They’ve got a bad reputation as one of the most dangerous shark species (they’re responsible for a large percentage of fatal attacks on humans and are sometimes called 'maneater sharks'), but it is possible to dive with tiger sharks safely. For our film crews, it’s all about experience, knowledge and taking the right precautions.
