Sea Urchin Free 3D Icon

A detailed isometric 3D sea urchin icon, perfect for ocean, marine biology, aquarium, and underwater themed projects. Its spiky purple form adds a distinctive natural touch to educational graphics, travel content, and sea life collections. Free to download and easy to use in digital designs.

Every Sea Urchin detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.

It suits ocean, marine biology, aquarium, underwater themed projects and marine life.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
