Not just Shark
Pictures: Elasmodiver contains photos of sharks, skates, rays, and
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
There are now
more than 5000 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:
Leading edge of hammer
well rounded (spade-like). Grey or grey brown dorsum often with small dark
length 150cm. 35 - 40cm at birth.
In shore mud/sand flats. Also, coral reefs, estuaries, and channels. Intertidal to
and distribution: Atlantic and Pacific coasts of the Americas
England to southern Brazil, and California to Ecuador.
A social shark usually in groups of three to fifteen animals. Migratory. Feeds
on crustaceans, bi-valves, cephalopods, and small fishes.
The hammerheads as a group are considered the most highly evolved of the shark families. 4 -
16 pups in a litter.
Similar species: Scoophead
Smalleye Hammerhead Shark, and Mallethead Shark each share part of the Bonnethead
shark's range but all can be distinguished by their slightly broader, more
hammerhead like heads.
Reaction to divers:
I have not dove with this species but judging by the lack of good photographs in
the wild I would imagine that the Bonnethead is a difficult shark to approach.
Information on dives where Bonnetheads are often seen would be appreciated.
