For those who might be curious, you can still buy actual sponges (Porifera) for your sponging needs. I'm posting in part because I recently had a conversation with a person who argued that loofahs (gourds in the genus Luffa that can be dried) were actual sponges. Useless trivia for the party this weekend. #sponges #squashes #porifa #cucurbitaceae #hippospongia
