Relating to the mouth.
The oscular opening of the sponge allows water to flow through it.
Ocular is derived from the Latin root "oculus" (meaning eye). The prefix "oscul-" comes from the Latin "osculum" (meaning little mouth or kiss). The word "oscular" refers to something related to the act of kissing or the mouth, often used in a poetic or romantic context.
Think of the Latin word for eye, 'oculus', and remember that 'oscular' relates to kissing, as it evokes the image of lips coming together like eyes meeting.
