Crinoid

Somebody needed Crinoid for animal and marine, so here it is. It earns its place in wildlife and nature layouts. Take it free as a transparent PNG. Commercial work is covered and attribution is optional, which is to say unnecessary.

Every Crinoid 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 a 3D render, on a transparent background, with no mask to draw.

Used alongside other Nature & Plants icons it holds its weight visually, so a row of them looks composed rather than assembled.

Common homes for it are sustainability reports, gardening apps, weather widgets and outdoor-brand sites. Teams in green-tech, agriculture platforms, outdoor brands and conservation groups tend to use it most. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
