A larvacean (tunicate larva) and a ctenophore! From a seawater sample.Â
Larvaceans exist in a sort of limbo between vertebrate and invertebrate. In their larval form, they have a notochord (visible in the picture) and nerve chord, the precursors to our spines. They lose these features once they become adults, and take on the appearance of jello sacs or colorful rocks.Â
Ctenophores usually have two sticky tentacles to catch prey. Unlike cnidarians (sea jellies/jellyfish) they have no stinging cells.Â
The larvacean is now dead (RIP) but the Ctenophore was transferred to a makeshift aquarium. We’ll see if it grows or not!Â
Also shout-out to my friends and lab partners Bianca and Michael for finding these!
