Imam Sajjad (PBUH) said: The right of your child is that you know that he has emerged from you and in this world, his right and wrong are attributed to you. You are responsible of his fine teaching and training, guiding him to his Lord, Almighty, and, assisting him to obey Him. Therefore, be sure that if you do a favour to your child, you will obtain it; and if you act viciously against him, it will come back to you, too.

Greenland sharks are not fussy eaters and consume a variety of fish, squid, and carrion. Stomach contents of sharks have even included polar bears, horses, and reindeer. Evidence suggests they may be opportunistic hunters capable of ambushing seals in stealth attacks. They have been linked to the discovery of nearly 5,000 mutilated seal corpses in Nova Scotia between 1993 and 2001: The victims’ pelts were ripped off in a spiral shape—like a peeled orange—giving the shark the gruesome.

Greenland sharks have narrow, pointed upper teeth and broader, squared teeth on the lower jaw. Holding large prey in position with their upper teeth, they roll their head in a circular motion, using the lower teeth like a blade to tear off circular chunks of flesh. Smaller prey is eaten whole.

The Holy Prophet (peace be upon him and his progeny) said: When your children are grown up to seven years, teach them the prayers, and when they are ten years old, seriously admonish them for it (in order that they establish prayers); and separate their sleeping beds from each other.

Dark gray, brown, or black with a cylinder-shaped body, small eyes, rounded snout, and no anal fin, Greenland sharks resemble a submarine and can reach 23 feet long and may weigh 1.5 tons. In comparison, the great white shark grows to 15 to 20 feet but is significantly heavier, weighing 2.5 tons or more.

Imam Ali (PBUH) said: The right of a child upon his father is that he should give him a nice appellation, train him well and teach him the Quran (with its rules).

Specially adapted for cold water, this shark’s tissues contain high levels of chemical compounds that act like anti-freeze and prevent ice crystals forming in the body. These sharks conserve energy by swimming very slowly—about 1.12 feet per second—but can exhibit short bursts of speed to ambush prey.

Imam al-Sadiq (PBUH) said: Benediction of a man to his child is his benediction to his parents.

The largest fish in the Arctic Ocean—and the only shark found there year-round—the Greenland shark also inhabits the North Atlantic and Russian high Arctic. Infrequently observed at the surface, it can live in waters 7,200 feet deep and between 28.4 to 44.6 Fahrenheit (minus 2 to 7 degrees Celsius).

Imam al-Sadiq (PBUH) said: Take action in teaching traditions (of Ahl Al-Bayt) to your children before the corrupted persons precede in corrupting them.

Measuring the Greenland shark’s growth rate is challenging because individuals are rarely recaptured. However, one shark tagged in 1936 had only grown 2.3 inches when it reappeared 16 years later.
