🦒 Recent genomics research confirms four distinct giraffe species, revealing extensive hybridization in North American captive populations. To ensure effective conservation, authors recommend phasing out hybrids and creating new, genetically pure stocks through international collaboration.

An #Invertefest mystery! I don't know what this is. I *think* it might be the mouth and tentacles of a buried sea cucumber of some sort, but I don't recall it doing the usual food-to-mouth transfer that you often see with those. Maybe it's a small aquatic Sarlacc?
