Acinetospora crinita is a species of brown alga in the family Acinetosporaceae. It is found in the temperate northeastern Atlantic Ocean and the Mediterranean Sea.[2]
Acinetospora crinita forms slender, irregularly branched filaments some 25 to 35 μm in diameter. These consist of strands of cells, each up to three times longer than they are broad, of a pale brown or yellowish-brown colour. Each cell contains several disc-shaped chloroplasts and a pyrenoid. The tips of the filaments are rounded; the filaments are often tangled with other algae forming bushy tufts which can grow to a length of several metres. This alga can be distinguished from other similar species by the branches growing perpendicularly from the filaments, and often emerging from the middle of a cell.[2]
Distribution and habitat

Acinetospora crinita occurs in the temperate northeastern Atlantic Ocean and the Mediterranean Sea.[2] It is also considered to be part of a cosmopolitan species complex, being reported from Bermuda, the Caribbean Sea, the Pacific Ocean and elsewhere, and has been described as "enigmatic".[3] Where it does grow, it sometimes consists of fragments of as many as thirty different species intermingled, with the different strains thriving in varying conditions and at different times of year. It forms a more or less complete covering of filamentous algae over the rock, detritus, living animals and sea grasses on the seabed in its habitat; its depth range is 5 to 40 m (16 to 131 ft).[2]
