Sycon huinayense is a species of sponge found on light-exposed vertical substrates at depths of 6–10 m (20–33 ft).

[1] They are associated with the mussel species Mytilus chilensis.

The type locality is Comau Fjord, Chile.

It was named after Fundación San Ignácio del Huinay.

[1] The zygote develops into either coeloblastula or amphiblastula larva (free-swimming) before settling down on a substrate where it grows into a young sponge.
