Eurasian Eagle Owl

Eurasian Eagle Owl is owl who's range is Real Madrid to Korea. It's wingspan is about 188 cm.It is 56 to 75 meters long weigh up to 1.75 kilograms.

Habitat

Although found in the largest numbers in areas sparsely populated by humans, farmland is include in their habitat types and they have even been observed living in park-like settings within European cities. Since 2005, at least five couples have nested in Helsinki. This is due in part to feral European rabbits (Oryctolagus cuniculus) having recently populated the Helsinki area, originally from pet rabbits released to the wild.

Behavior

The song, which can be heard at great distance, is a deep resonant ooh-hu with emphasis on the first syllable for the male, and a more high-pitched uh-hu for the female. These calls are repeated at intervals of up to a minute. Other calls include a rather faint OO-OO-oo and a harsh kveck-kveck. Annoyance at close quarters is expressed by bill-clicking and cat-like spitting, and a defensive posture involves lowering the head, ruffling the back feathers, fanning the tail and spreading the wings.

SAVE ANIMALS

—It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.

Pacific Electric Ray

Pacific Electric Ray is electronic ray that found in Pacific ocean. The Pacific electric ray has a soft, flabby body devoid of dermal denticles.

Taxonomy

n 1861, Theodore Gill placed this species in his newly created genus Tetronarce, on the basis of its smooth-rimmed spiracles. Later authors have generally regarded Tetronarce as a subgenus of Torpedo. Closely similar electric rays found off Peru, Chile, and Japan may be the same as this species. Other common names used for this ray include California torpedo ray, Pacific torpedo, or simply electric ray or torpedo ray.

Distribution and habitat

Off California, the Pacific electric ray is generally encountered at a depth of 3–30 m (10–100 ft), while off Baja California it is typically observed at a depth of 100–200 m (330–660 ft). It has been reported from as deep as 425 m (1,394 ft). This species prefers temperatures of 10–13 °C (50–55 °F). It frequents sandy flats, rocky reefs, and kelp forests. However, one individual has been videotaped 17 km (11 mi) west of Point Pinos, Monterey County, California, swimming 10 m (33 ft) below the surface in water 3 km (1.9 mi) deep; this and other observations suggest that this species makes periodic excursions away from shallow coastal habitats into the epipelagic zone.

Feeding

At night, when many diurnal fishes descend from the water column and become inactive a short distance above the bottom, the Pacific electric ray switches to an active hunting strategy. It stalks fish by slowly swimming or simply drifting through the water; when it closes to 5 cm (2.0 in) of the prey, it lunges forward and again envelops the prey within its disc while delivering shocks. To better secure the fish within its disc, the ray will make short kicks with its tail that sometimes send it into barrel rolls or somersaults.
