Shark Identification
This section describes basic identification features that should allow a diver with a good view of a shark to identify it. The sharks listed here are the species a diver is more likely to encounter in our region. They are grouped according to the following distinctive features for a preliminary assessment.
Sharks with conspicuous fin markings
Sharks with conspicuous body markings
Sharks without conspicuous fin or body markings
The diagrams give accurate taxonimic information about the various species. The small red sharks underneath a shark's name identify how dangerous this species is considered to ve a variety of contexts - to swimmers, surfers, spearfishermen and so on, rather than specifically to divers. The greater the number of small sharks, the higher the general threat - to a maximum of five. |
