The fascinating world of marine creatures never fails to surprise us, and the Tunicate salp, commonly known as a salp, is no exception. Resembling an elongated jellyfish without tentacles, these barrel-shaped sea squirts are actually more closely related to humans than jellyfish. Despite their gelatinous appearance, salps are invertebrates with a notochord, a kind of spine that runs down their back and anchors muscles.
Salps come in various sizes, ranging from tiny fractions of an inch to over a foot in length. Photographer Massimo Giorgetta recently captured an image of a two-inch salp off the coast of Indonesia, showcasing its transparent body filled with a surprising array of prey. This stunning photograph earned the bronze award in the Nature/Underwater category of the Tokyo Foto Awards.
Upon closer examination of the image, it’s hard to distinguish between the salp’s body and its prey due to its see-through flesh. However, a yellow blob resembling a small fish and some larval crabs and shrimps are visible inside the salp. These creatures likely got trapped in the salp’s feeding net, as salps feed primarily on phytoplankton but will consume anything they catch.
Inside the Tunicate salp captured by Giorgetta, one can spot a box fish in its juvenile form, small flatworms, juvenile Squilla mantis, heteropods, and several unidentified animals. The intricate ecosystem within the salp is a testament to the diversity and interconnectedness of marine life.
