Animals and birds of the White sea
Polychaete worms (polychaetes, a type of round worms) usually occur in the coastal zone. Buried in the sand, they expect the tide to lean out from his hiding place. These are pushily – the inhabitants of the sandy shallows. But there is deep-sea polychaetes, such as Nereid pelagic, living in the soft mud in the depths of the White sea.
“Pelagic” is called the organisms living in the pelagic – in the water or on its surface. Why is the bottom dweller of the Nereid called pelagic? It turns out that once a year, in summer, long Arctic day, all Nereids float to the surface to spawn. It is unclear how the worms managed to simultaneously leave their homes and that is their signal to the ascent. Spawning Nereids light for fish and marine birds – “time to eat”. Caviar Nereids eating not only animals. Fried eggs this large worm, similar in flavor to fried, is a favorite dish of the locals.
ANGEL, DEVOURING THE HELL
Far from shore in the water column hovering angel. This is a small krilangi clam, smoothly waving translucent pinkish wings – outgrowths on the foot. Angelfish hovers vertically in the water, amazing grace. Looking at this miracle, and not think that before us is a voracious predator, the main production of which smaller predator – krilangi clam monkfish.
Monkfish malchevskogo angel and painted, as befits the devil, in black color. His defense is a fragile shell, where he hides when in danger. But the angel of the sea shell is not a hindrance. Easily destroying its tentacles, pulls the angel in the hell mouth. In translucent the body of Angela long will be seen the traces of “black Affairs” – the remains swallowed by hell.
The devil and angel common enemies – fish and cetaceans. The cold and the storm are on krilanovich the same – they fall into the deep and fast, deprived of the opportunity to hunt.
FROM COASTAL WATERS TO DEPTHS OF
In the coastal zone of the White sea meet two Atlantic species – baldyga (30-60 cm) and Maslyuk (approx. 24cm). These fish select shallow water with sandy or rocky bottom. There they feed on crustaceans, molluscs, fish eggs and fry. These fish belong to different families (bildukevich and Maslakovic), but one squad okuneobraznyh. Bellugi – viviparous fish, for the North is a rarity. The locals prefer not to eat fish that “whelps”. Besides, during cooking dice the green Bellugi, causing the fishermen distrust of the quality of the meat. However, the meat of bildug very tasty and the Baltic that is also found Biel Dugi, is considered a delicacy. Inhabits in the coastal waters similar to bulls of European kerchak 3 (35 – 60 cm) fish of the family karshakevich Kerzhakov male bright plumage: grayish-brown back with dark spots turns into an orange flanks with white spots and a white belly. Males guard the eggs after spawning. Hatched, the fry go free swimming in the water column. As adults, they return to the coastal area and live near the bottom, feeding on fish and crustaceans.
One of the most amazing fishes of the White sea – pinagor (30 – 60 cm), or fish-Sparrow 4 family pinegrove. This almost round fish, decorated with rows of bony outgrowths, there is a bottom dweller, inhabitant of coastal waters. Such a “ball” at low tide could easily carry into the open sea. However, adult pingora – homebodies. So they got a special suction Cup on the belly, which is tightly attached to rocks. This round sucker – modified ventral fins. These have suction cups and fry pinegrove, but youth they just need to travel. The fry are attached to the algae, and the current carries them into the sea. So pinagare settled. Growing up, fish returned to the coastal area. In the mating season panagora “dress up”: the belly and the fins get the carrot color and the back is all black, with a greenish tinge.
Carcaci and panagora included in the squad of scorpene-shaped. This squad includes the commercially valuable species like groupers (family of skorinova). More than a million years ago, deep-sea perch from the Pacific ocean via the Arctic into the North Atlantic, where they formed new species. In the White sea at great depths meet the North Atlantic species of redfish (45 cm), 5 small (35 cm) and 6 gold (80 -100 cm) sea bass. Groupers – mobile pelagic fish. During the day they rise closer to the surface, then again go to the depth. The fins of the sea bass covered with poisonous spines. Painful wound from the barb collarbone.
Due to the active catch abundance of sea perch decreased significantly. Slow growth rate and late maturity of perch is the cause of rebuilding their livestock.
BELUKHA AND SEALS
The White sea is white and white whales. Milky white color that gives name to the Beluga whales, these dolphins only get growing up. Young people are painted in grey or blue color. The white whale is the largest Dolphin (length 6 m, weight 2 t). Unlike other dolphins,
she has small and oval pectoral fins, no long beak and dorsal fin.
Beluga whales are very “talkative” – they loudly chirping, roaring and howling. The phrase “roars like a Beluga” means “silent” Beluga fish, a Dolphin. The prey of Beluga whales, cod, herring and squid.
In the White sea there are a few kinds of true seals. Among the smallest of the Northern seals, 8 ringed seals (110-150 cm to 80 kg) – close relatives of the Caspian and Baikal seals. In the White sea is home to the largest Russian seal – bearded seal, or sea hare (up to 240 cm, 300 kg). Lush stiff whiskers help the seal at the bottom to find crustaceans and molluscs. Bearded seal can hunt and fish, such as cod. Seals are more agile HUNTERS, and although their menus are found crustaceans, they are more likely to catch fish is the saffron cod, smelt, capelin.
Seals and sea hares don’t make long migrations, and prefer coastal areas and small depth.
