Annelida, (polychaetes and sea leeches); Brachiopoda, marine animals that have hard "valves" (shells) on the upper and lower surfaces ; Bryozoa, also known as moss animals or sea mats; Chaetognatha, commonly known as arrow worms, are a phylum of predatory marine worms that are a major component of plankton;
They are clumsy on land, and move on land by lunging, bouncing and wiggling while their fore-flippers keep them balanced; [29] when confronted with predators, they retreat to the water as freshwater phocids have no aquatic predators. [48] The pygmy hippopotamus has four weight-bearing limbs, and can walk on land like a fully terrestrial mammal.
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
Hawaiian monk seals grow to be 6-7 feet long, weigh 400-600 pounds, and can live more than 30 years. Males and females are generally the same size — the only way to tell them apart is to look at ...
Risso's dolphin (Grampus griseus) is a marine mammal and dolphin, the only species of the genus Grampus.Some of the most closely related species to these dolphins include: pilot whales (Globicephala spp.), pygmy killer whales (Feresa attenuata), melon-headed whales (Peponocephala electra), and false killer whales (Pseudorca crassidens).

The post Scientists just discovered a massive sea predator from the Triassic period appeared first on BGR. According to a new study, scientists believe the largest animals to ever live, lived in ...
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
Dulcibella camanchaca is a species of amphipod crustacean discovered in the Atacama Trench, at depths of nearly 8,000 m (26,000 ft) in the South Pacific Ocean near Chile. [2] [3] Measuring approximately 4 cm (1.6 in) in length, this predatory amphipod is adapted to the extreme conditions of the hadal zone, making it one of the deepest-living predators identified to date.
