Scientists are increasingly told to be visible. But how do we reach the right audience? Our colleagues in the field know about the work from papers and reports, but how do we reach the community to let the results have real world impact? 🌐 🧪 🦑 🐙 #SocialMediaForResearchImpact

Science and marine life folks! Does anyone on here study sea anemones (or know someone who does)? I'm particularly interested in talking to someone about the biomechanics of their tentacles and stinging cells. 🧪🦑

In the Arabian Sea, the biomass of lanternfishes is particularly high, but dominated by only a few species. Much of the high production of the Arabian Sea is channelled via zooplankton to the stock of lanternfishes due to the low abundance of competing small pelagic fish.

#CrabAZ never ignores memes. M is for Macrocheira. This is both the largest arthropod alive (3.8 m or 12 ft leg span, only males are this extreme) and the only living species in its family. Mainly found in Japanese waters up to 600 m depth. (Yes we know it's Thursday, sorry) 🦀🧪🦑

The larva of a Ctenophore (comb jelly), probably Pleurobrachia pileus. Comb jellies like the sea gooseberry are often mistaken for jellyfish. Unlike jellyfish, comb jellies don’t have stinging cells to capture their prey, instead having sticky tentacles. 🦑
