Species context
Each strong species page explains what the shark is, where it lives, and what makes it notable.
Shark field guide
A calmer, more useful way to learn shark species.
Pocket Shark Field Guide is an independent reference site and iPhone app built around shark identification, species context, comparison, and offline study. The goal is simple: answer real shark questions clearly, then give readers a field guide they can keep.
What this site is for
This site is designed to work as a shark reference first. It focuses on species identity, habitat, conservation context, and comparison instead of flattening every page into the same repeated layout.
Topic-led browsing
A smaller set of topic hubs connects related species instead of scattering authority across hundreds of nearly identical pages.
Offline field guide
The app remains available for people who want the guide on iPhone, but the site is written to stand on its own as a useful reference.
How the guide is organized
Readers usually arrive with one of three needs: a specific species, a broader shark group, or a practical comparison between similar sharks. The site is being narrowed around those stronger intents.
Species pages
Focused entries for individual sharks with cleaner factual summaries and fewer placeholder metrics.
Topic hubs
Broader pages for groups such as hammerheads, catsharks, and Gulf of Mexico sharks.
Comparisons
A smaller set of contrast pages for pairs people often confuse or research together.
Core topic hubs
These are the stronger internal-linking hubs for the current guide. They are intended to concentrate authority instead of spreading it across thin templates.
Deep-Sea Sharks
Sharks that spend much of their time in deeper offshore water columns and slopes.
Small Shark Species
Compact shark species for readers looking for tiny, pocket-size, and short-bodied sharks.
Giant Shark Species
Large sharks with headline body sizes that make them useful anchor terms for comparison pages.
Gulf of Mexico Sharks
Species in the catalog with Gulf of Mexico coverage, including the American pocket shark.
Hammerhead Sharks
Hammerhead and bonnethead species for users searching by common head shape rather than taxonomy.
Catsharks
Catshark and close catshark-family pages generated from the offline shark catalog.
Featured species
These species currently have enough structure and editorial context to work as public reference pages.
