SHARK FINS
Shark fins are one of the most iconic and vital parts of a shark’s anatomy. The most recognized is the dorsal fin, famously seen slicing the ocean’s surface. However, sharks also have several other fins that help them maneuver and swim effectively:
- Dorsal Fins – Provide stability and balance; sharks may have one or two depending on the species.
- Pectoral Fins – Located just behind the gill slits; function like steering wheels.
- Pelvic Fins – Help maintain lift and stability; located on the underside.
- Anal Fin – Adds stability; not present in all species.
- Caudal Fin (Tail Fin) – Generates thrust to propel the shark forward.
These fins are supported by keratin-based elements called ceratotrichia, which resemble dry spaghetti. This material is what’s commonly used in shark fin soup.

Why Sea Cucumbers Matter
- Essential for nutrient recycling and substrate oxygenation on coral reefs.
- Help maintain healthy marine ecosystems.
- Found in shallow coral reefs and seagrass beds globally.
- Out of over 1,200 species, only ~70 are traded internationally.
- High-value species:
• White teatfish (Holothuria fuscogilva)
• Black teatfish (Holothuria nobilis)
• Black teatfish (Holothuria whitmaei)
• White teatfish (Holothuria fuscogilva)
