Little Shark Amigurumi Crochet Pattern

Make a cute, speedy amigurumi shark—perfect as a plush or keychain! This pattern is written with both standard crochet instructions and easy explanations for beginners. Each section is clearly separated so you can easily follow along, whatever your skill level.


Crocheting Checklist

  • Brush up on basic amigurumi stitches: magic ring, single crochet, increase, decrease, working in the round.
  • Review invisible decrease and surface embroidery for gills and mouth.
  • Set up your workspace with all tools in reach, including safety eyes and stuffing.

Pattern Overview

  • Shark body is worked in the round from nose to tail.
  • Fins and tail are made separately and sewn to the body.
  • Stuffing is added partway through, so keep a yarn needle near.
  • White and black yarn for mouth, gills, and eye accents.

How I Created the Shark Pattern

  • Crocheted the shark body in seamless rounds, shaping with increases/decreases.
  • Added safety eyes early, before closing the body.
  • Made fins and tail as separate pieces, then attached them securely.
  • Embroidered the mouth, teeth, and gills for detail.

Explanatory:
Start with a magic ring and work increases to widen the nose. Next, add single crochets to build length; the safety eyes are added after the structure is established. Place them facing forward, about halfway up the head.

  1. Next round: (sc x 3, dec) x 6 (24)
  2. Next round: (sc x 4, dec) x 4 (20)
  3. Next round:

  1. Next round: dec, sc, dec, sc x 2, dec, sc, dec (8)
  2. Last round: dec x 4 (close up) (4 stitches; thread needle, sew closed.)

Explanation:
Work decreases to taper the body, matching the typical shark shape. When you get to about 12 stitches, fill the body firmly with stuffing.


GILLS

  • Embroider 2–3 lines behind each eye, using black yarn and a yarn needle.
  • Make one line crossing 3 stitches, another crossing 2 stitches, spaced above and below.

Explanation:
Use black yarn to add detail near the eye—these are shark gills. Mirror on both sides.


FINS

Main Fin (Make 3)

  1. Magic ring, 6 sc.
  2. Next row: sc x 2, inc x 2, sc x 2. (8)
  3. Next row: sc x 3, inc x 2, sc x 3. (10)
  4. Repeat: Make 2 more identical fins.

Explanation:
Make three slightly larger fins—the dorsal (top) and side fins. Start from a magic ring, increase for shape.

Side Fins (Make 2)

  1. Magic ring, 5 sc.
  2. Next row: inc in 1st st (2 sc), sc in next 4 sts. (6)
  3. Next row: sc in each st. (6)
  4. **Repeat: Make one more fin._

Explanation:
Smaller side fins near the tail; start with a magic ring, add a row for dimension.


TAIL FIN

  2. Next row: sc x 2, inc x 2, sc x 2. (8)
  3. Next row: inc, sc, dec x 2, sc, inc (8)
  4. Next row: sc x 2, dec, sc x 2, dec (6) Finish off.

Bottom Tail

  1. Magic ring, 6 sc.
  2. Next row: sc x 2, inc, sc x 2, inc (8)
  3. Next row: sc x 2, dec, sc x 2, dec (6) Finish off.

Summary:
Make two pieces for tail—top and bottom—then sew together for a full tail fin.


ASSEMBLY & FINISHING

  • Sew on three large fins: one centered (dorsal), two on each side behind the gills.
  • Sew small fins to the rear sides of the shark body.
  • Attach tail: sew top fin on top, bottom fin below at the tail base.
  • Add stuffing if needed, sew body closed.
  • Embroider a mouth with white yarn, add teeth with small stitches.
  • Weave in all threads; trim excess.

Problem & Solution

Common Issue: Shark body looks uneven or fins floppy.

Remedy:
Double check stitch counts in shaping rounds; stuff firmly. When sewing fins/tail, use small, tight stitches and reinforce by running the thread back and forth. For floppy fins, use slightly smaller hook or edge with slip stitches.
