Alexandrium minutum is a small, armored marine dinoflagellate known for producing saxitoxins responsible for paralytic shellfish poisoning. It inhabits coastal and estuarine waters in temperate to warm oceanic regions worldwide. This photosynthetic protist can form harmful algal blooms that cause toxin accumulation in filter-feeding bivalve shellfish.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.
