Aggregating anemones (anthopleura elegantissima) have specialized tentacles called acrorhagi (white-tipped tentacles in the photo) that are used to fight other invading colonies of anemones. each colony consists of genetically identical clones. when they sense a non-clonemate, the anemone closest extends its acrorhagi to attack the competing anemone with stinging cells called nematocytes.

this is a type of rattail fish called “coryphaenoides acrolepis” they’re only found below 1000 metres and generally live closer to the sea floor. these fish grow slowly and may not reproduce until they’re 30-40 yrs old! 🐟
