WHAT IS ELASMODIVER?

Not just a huge collection of Shark Pictures: Elasmodiver.com contains images of sharks, skates, rays, and a few chimaera's from around the world. Elasmodiver began as a simple web based shark field guide to help divers find the best places to encounter the different species of sharks and rays that live in shallow water but it has slowly evolved into a much larger project containing information on all aspects of shark diving and shark photography.

There are now more than 10,000 shark pictures  and sections on shark evolution, biology, and conservation. There is a large library of reviewed shark books, a constantly updated shark taxonomy page, a monster list of shark links, and deeper in the site there are numerous articles and stories about shark encounters. Elasmodiver is now so difficult to check for updates, that new information and pictures are listed on an Elasmodiver Updates Page that can be accessed here:

Common Names: Smooth hammerhead shark, Common hammerhead shark, Smooth common hammerhead shark. 

Latin Name: Sphyrna zygaena

Family: Sphyrnidae  

Identification: Leading edge of hammer scalloped with two well defined indentations. No prominent central indentation. Fins mostly plain with slight dusky tips. Caudal fin trailing edge dusky especially on lower lobe. 1st dorsal fin high, second much lower. Dorsal surface olive grey  to greyish brown. Ventral surface pale. 

Size: Maximum length 500 cm. 42 - 55 cm at birth.  

Habitat: Inshore to offshore continental shelves.  1 to 200m but usually shallow.

Abundance and distribution: Widespread, in most subtropical / temperate oceans. Often over bottom between 1 and 140m. In eastern Atlantic from Britain to Ivory Coast including the Mediterranean. Western Atlantic from Canada to northern Caribbean and Brazil to Argentina. Indian Ocean from South Africa to Sri Lanka. In the western Pacific around Hawaii, Southern Australia, New Zealand and from Vietnam to Southern Siberia. Eastern Pacific from Northern California to Chile.

La Paz Bay has been identified as one of many birthing and nursery grounds for juvenile Smooth Hammerhead Sharks.

Feeding Behavior: Feeds mainly on smaller sharks and rays. Also on bony fishes, shrimps and molluscs. 

Reproduction: Viviparous. Hammerhead sharks are considered the most highly evolved of the shark families. Smooth hammerhead sharks become sexually mature at 250-300cm in length.

Photographs: La Paz Bay, Baja, Mexico.  

Similar species: The smooth hammerhead shares much of its range with the scalloped hammerhead Sphyrna lewini which has a distinct cleft in the centre of the leading edge of it's hammer. The great hammerhead Sphyrna mokarran has a much straighter leading edge to it's hammer, proportionately taller dorsal fin, and larger terminal size. 

Reaction to divers: Shy. Very difficult to approach. Divers may have better success when using rebreathers.

Diving logistics: The images of the Smooth Hammerhead Shark on Elasmodiver were taken of a juvenile specimen released from a longline in La Paz Bay.

Any locations where Smooth Hammerhead Sharks can be seen or photographed in the wild would be welcome.
