About the Sea Urchin Circle Badge black outline icon
A round urchin body edged with sharp zigzag spines sits inside a thin circular frame, three small rings marking its top shell. It reads as marine life, tide pools, coastal ecology and seafood delicacies. Useful in aquarium and marine biology sites, diving and snorkeling tour pages, sushi and seafood restaurant menus, ocean conservation campaigns, and beach or nature-themed presentations and stickers.
The spines are drawn as an even star-like ring of triangular points, giving a compact silhouette that stays recognizable at a glance, while the outer circle turns it into a badge that matches other framed sea icons. It pairs with starfish, shell, coral and jellyfish symbols. Keep it at 32 px or larger so the fine spikes do not blur together.
This is the black outline version of the sea urchin circle badge icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
