🪸Tricky Taxon Thursday: Balistes capriscus🪸
The grey triggerfish has a remarkable defense: its first dorsal fin locks upright, securing it in rocky crevices. With powerful jaws, it crushes crabs and molluscs and flips urchins. Occasionally visiting UK shores during summer. See 106 records here👇

🌊🐟 Sea Spectacles returns! 🪼🫧

This month’s star: the St Piran’s Crab (Clibanarius erythropus) ✨

In 2016, BBC Springwatch held a contest to name this species — the winner was “St Piran’s Crab,” inspired by Cornwall’s sea-surviving patron saint.

🪸Tricky Taxon Thursday: Tubularia indivisa🪸
The Oaten Pipes Hydroid is a striking UK invertebrate, forming vibrant pink-orange clusters resembling flowers. Seen in spring, they're often a nudibranch's meal. Despite their anemone-like form, they're closer to jellyfish. See 5000+ records here👇
