Hooded Seal (Cystophora cristata) Mom makes it clear that her SUPER MILK of seal kindess  ;) is only for her pup.   

How Do Hooded Seal Pups Survive in the Arctic? 

Hooded seal mothers produce milk with the highest fat content of any mammal, and they have the shortest lactation period, as well. Born on ice floes in the freezing North Atlantic and Arctic oceans, seal pups are fed milk that contains at least 60 percent fat.

This helps them to quickly pack on a thick layer of blubber for insulation against the harsh environment. Mother seals remain with their pups for only four days, feeding them about 16 pounds (7 kg) of milk a day, which allows the pups to quickly double in size. 

Got milk?  ;D

Human breast milk contains about 3 to 5 percent fat, although the fat content can change dramatically over the course of a single feeding. The total fat content continues to increase from three months after birth.

A cow’s milk is similar to a human’s, but rats, dogs, and rabbits all provide their offspring with a milk with a higher fat content.  :o

Higher amounts of protein in milk help animals build muscle faster, while milk with more carbohydrates helps with brain development, according to La Leche League International.


Description & Behavior

Hooded seals ARKive - Hooded seal videos - Cystophora cristata

Hooded seals, Cystophora cristata (Erxleben, 1777), aka Cystophora borealis, Phoca cristata, are named for the large elastic sac that extends from their noses to their foreheads that expands into a large balloon-like ball in the adult males.

Hooded seals have a black face and a blue-gray coat with patterns of dark patches. Adult males measure an average of 2.5-3 m in length and weigh about 300-400 kg. Adult females are smaller, measuring an average of 2-2.4 m in length and weighing about 160-230 kg. Hooded seals are known to dive repeatedly to over 1,000 m for more than 50 minutes. The life span of the hooded seal is 30-35 years of age.

Hooded seals are very aggressive compared to other seal species. Adult males demonstrate their aggression by inflating their "hood" (balloon-like ball on their face), which can grow to twice the size of a football.

The "hood" is an enlargement of the nasal cavity which develops at about 4 years of age. When inflated, the hood forms a balloon on the head, when deflated the hood hangs in front of the upper lip. Males also have an inflatable nasal membrane that expands like a red balloon from one nostril that "pings" when shaken. The hood and membrane are used for aggression display when threatened and as a warning during the breeding season.

Even Scientists Were Blown Away by These Weird Sea Creatures They Found

November 21, 2017


Scientists aboard the ocean-exploring ship the E/V Nautilus have been prowling the ocean for wonders since 2008, literally just exploring the seas.

So after spotting a sperm whale, a googly-eyed squid, and a host of other wonders, you’d think they may be jaded. It turns out they are not. Case in point: their reactions to finding a vampire squid and a Deepstaria jelly on a recent journey around the Revillagigedo Archipelago, a series of islands about 375 miles off Mexico’s Pacific coast.

They brought back video captured from a Remotely Operated Vehicle (ROV), including hosting an impromptu laser light show on the jelly (Pink Floyd soundtrack not included). According to the E/V Nautilus YouTube page, this is the first ROV footage ever captured around the Revillagigedo Archipelago.

Deepstaria jellies typically occupy cold waters around the Arctic and Antarctic, making their appearance here, even in the cold depths of the tropical Pacific, somewhat of a mystery.

Scientists also found the vampire squid about a mile underwater. Its full name translated from Latin is actually “vampire squid from hell,” which makes it the most bad ass of all sea creatures.   ;D
