Despite being over 95% water, traditionally processed and dried jellyfish contains approximately 5.5 to 6 grams of protein per 100 grams, a nutritional profile that surprises many. The unique gelatinous texture of edible jellyfish makes it a low-calorie addition to various dishes, valued not just for its taste but for the protein it provides.

Live phytoplankton forms the base of nearly all marine food webs, supporting countless ocean creatures. For home aquariums, understanding what are the benefits of dosing live phytoplankton is key to creating a balanced and vibrant reef ecosystem.

Yes, the Mediterranean Sea is home to a rich and commercially important diversity of shrimp species. Far from being an empty sea, the basin hosts a variety of crustaceans, from deep-dwelling red shrimp to more coastal dwellers like the spot-tail mantis shrimp, all of which contribute significantly to the local cuisine and economy.

The Mediterranean Sea is considered a biodiversity hotspot and contains approximately 7% of the total global marine fish species, an unusually high diversity for a temperate sea. The question, 'Does the Mediterranean have fish?' therefore reveals a vibrant, complex aquatic ecosystem with both abundance and considerable conservation challenges.

According to fisheries data, kelp forests provide critical habitats and are one of the most productive ecosystems on Earth. However, many people wonder what does edible kelp look like when they are considering it for their dinner table or foraging on the coast.

Many people look to the sea for natural nutrition, but not all seaweeds are created equal when it comes to mineral content. A single gram of dried kelp can contain iodine levels far exceeding the recommended daily intake, emphasizing the need for caution. This guide explains which seaweed contains iodine and helps you understand the differences for safe and healthy consumption.

With over 30,000 known species, the diversity of fish is staggering, and their skeletal structures are no exception. A common misconception is to ask, "are fish bones all cartilage?", but the truth is a crucial division exists between fish with bony skeletons and those with cartilage.

A surprising fact of animal physiology is that fish, unlike birds or reptiles, do not excrete uric acid as their main nitrogenous waste product. This fundamental difference in metabolism explains how fish efficiently dispose of toxic ammonia and other waste, a critical process for survival in their aquatic environment.

The Sinarapan (Mistichthys luzonensis) was once so abundant in the Philippines' Lake Buhi that it was scooped up with fine nets. This tiny fish, measuring only about 2.5 centimeters long, is now critically vulnerable, with its primary population now thriving in the remote Lake Manapao.

Scientific research shows that astaxanthin is a super-antioxidant, and its primary source is the microalgae *Haematococcus pluvialis*, which can produce concentrations over 1,000 times higher than wild salmon. However, this vibrant red carotenoid can also be obtained from marine animals that consume the algae and through dietary supplements.
