Strange sea creature found on Australian beach

Catherine Nguyen spotted something that looked like a swollen tongue when she was walking along the beach on Moreton Island.

According to specialists from Queensland Museum it's a cavernularia obesa, or sea feather, which consists of numerous interconnected animals that are grouped into colonies.

Sea feathers use their tentacles to collect food and to defend themselves and experts are warning anyone who finds one not to touch them, because they also deliver a nasty sting.
