According to nutritional data, a 3-ounce serving of cooked snails contains about 17 grams of protein. This confirms that a snail does have protein and is, in fact, a significant source, often compared to conventional meats like beef and pork but with a considerably lower fat content.

Many people assume all marine life has red blood, but some creatures, most famously the Antarctic icefish, have a clear circulatory fluid instead. The answer to what seafood has no blood extends beyond this single species to include a fascinating array of invertebrates with unique survival strategies.

With over 85,000 species, the class Gastropoda is the largest group within the phylum Mollusca. Many people mistake these slow-moving creatures for insects, but what does a snail count as in biological terms? The definitive answer lies in their unique classification and characteristics, which set them apart from the insect world.

Calcareous sponges, which comprise the class Calcarea, are characterized by their unique calcium carbonate skeletons and account for approximately 675 accepted marine species. Identifying Calcarea requires a keen eye for physical characteristics, such as spicule type and body shape, and an understanding of their preferred habitats in the marine environment. While they can be found globally, most species prefer shallower, sheltered waters, offering a clearer path to differentiation.
