Common Spiny Lobster

<em>Palinurus elephas</em>, commonly known as the common spiny lobster, is a large marine crustacean in the family Palinuridae, distributed across the northeastern Atlantic Ocean and Mediterranean Sea. This species typically inhabits rocky and biogenic reef habitats at depths ranging from the shallow subtidal zone to approximately 200 metres, where crevices and caves provide shelter during the day. Its geographic range extends from the British Isles and the Azores southward along the Atlantic coasts of Europe and North Africa, and throughout the Mediterranean. The species has not been formally evaluated under IUCN Red List criteria, though commercial populations have declined significantly across much of its range due to intensive fishing pressure. <em>Palinurus elephas</em> lacks the large claws characteristic of true lobsters, relying instead on long, spiny antennae for defence and sensory purposes. It is omnivorous, typically feeding on molluscs, echinoderms, algae, and organic detritus on the seafloor. The species can reach a total body length of approximately 50 cm and may weigh up to approximately 4 kg in large individuals, though average lifespan measurements remain poorly documented. Spawning occurs in summer, with females carrying egg masses under the abdomen. Commercial fisheries management increasingly focuses on minimum landing sizes and seasonal closures.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
