Start with a few durable sets
Hammerheads, filter-feeding sharks, coastal look-alikes, and flattened ambush sharks are enough for a useful first deck.

These printable comparison cards turn the site's strongest side-by-side shark questions into a classroom-friendly format. They work best as quick prompts for sorting shape, habitat, and standout cues before students move into the full guide pages.
This page is also available as a printable PDF for classrooms, quick reference, and offline use.
Hammerheads, filter-feeding sharks, coastal look-alikes, and flattened ambush sharks are enough for a useful first deck.
The cards are strongest when they focus on shape, habitat, and one or two standout clues instead of overstuffed fact lists.
Each card set should lead into a stronger comparison page, species profile, or worksheet rather than becoming a disconnected classroom extra.
| Card set | What students compare | Best follow-up page |
|---|---|---|
| Hammerheads | Bonnethead, scalloped hammerhead, and great hammerhead head shape and overall proportions | Hammerhead Species Comparison |
| Filter-feeding sharks | Whale shark, basking shark, and megamouth as a cluster | Filter-Feeding Sharks |
| Coastal pair 1 | Blacktip versus spinner in nearshore water | Blacktip Shark vs Spinner Shark |
| Coastal pair 2 | Bull versus lemon when body build and habitat overlap matter | Bull Shark vs Lemon Shark |
| Flattened bottom sharks | Angel sharks versus wobbegongs as a body-plan comparison | Angel Shark vs Wobbegong |
These quick answers keep the page practical and point readers toward the next useful guide page.
No. It is a printable extension of the main field guide, built from the same comparison pages and intended to send readers back into them.
They work well for light classroom use, library tables, study groups, and quick marine-biology activities where students need a compact comparison prompt.
Usually no. The cards work best when you print one or two strong clusters at a time so the follow-up pages stay obvious and the activity stays focused.
Yes. The download link on the page provides a printable PDF version of the comparison-card set.
Keep moving through the field guide with the pages that make this one more useful.
A natural cluster for the first card set.
Another group that adapts well to cards.
A clean coastal pair for quick side-by-side sorting.
Another coastal pair that works well when students compare body build and habitat cues.
A flattened-body comparison that works well as a classroom prompt.
A worksheet that pairs naturally with the comparison cards.
Pocket Shark is built as an offline shark field guide for iPhone and iPad, so the same comparisons, glossary notes, and species context can stay with you away from a browser.
