The hammerhead sharks are a group of sharks in the family Sphyrnidae, named for the unusual and distinctive structure of these shark heads, which are flattened and laterally extended into a “hammer” shape called a “cephalofoil”.
Hammerheads are found in warmer waters along coastlines and continental shelves. Unlike most sharks, hammerheads usually swim in schools. This schools can be found in Sipadan Island location dive site at South Point.
The hammerhead sharks size range from 0.9 to 6 m (3.0 to 20 ft) long and weigh from 500 to 1000 pounds. Their bellies are white which allows them to be close to the bottom of the ocean as camouflage and blend in to sneak up on their prey.
Research that the hammer-like shape of the head may have evolved to enhance the creature’s vision. The positioning of the eyes give the shark good binocular vision, as well as 360-degree vision in the vertical plane, meaning these shark can see from above and below them at all times also help the shark find food.
Hammerheads have strangely small mouths and seem to do a lot of bottom-hunting. They are also known to form schools during the day, sometimes in groups of over 100.
Hammerheads are one of the few creatures that acquire a tan from prolonged exposure to sunlight. Tanning occurs when a hammerhead is in shallow waters or close to the surface for long periods.
Reproduction only happen once a year for hammerhead sharks and usually occurs with the male shark biting the female shark violently until she agrees to mate with him.
Hammerhead sharks are known to eat large fish, squid, octopus, crustaceans, and even other hammerhead sharks. Stingrays are a particular favorite. These sharks are common found along the bottom of the deep ocean and stalk their prey. Their unique shape of the head is used as a weapon when hunting down prey.
Semporna town (YouTube) is the gateway to Sipadan Island. There has been a growing interest in the dive sites in this region, including in the now-protected Tun Sakaran Marine Park which consists of eight islands and is the largest marine park in Sabah. All these dive sites have made Semporna more popular, and diversified the experience that one can gain while in Semporna. The name Semporna means place of rest and was given after the British quelled resistance from the local Bajaus in the mid-1880s, changing it from Tong Talun. Another story is that Semporna was called place to settle or meeting place. The majority of the population is Bajau, many of whom live in sprawling stilt villages over the water on the outskirts of town and is visited by tourists as a base for scuba diving or snorkeling trips to some of the country’s finest diving sites including the world knowned Sipadan Island and Mabul Island.
Semporna is also known for the Regatta Lepa traditional boat races which occur annually in April. Their unique Lepa Boat resembles the modern day’s catamaran vessels, with two adjoining legs for added stability when roughing the wild Celebes Sea.
Off the coast is a marine park called Tun Sakaran Marine Park also known as Semporna Islands Park. It was gazetted by Sabah Parks in 2004.
