Humpback takes seal under its flipper to cheat predators

There are plenty of stories of cetaceans saving humans. Indeed, Jonah was rescued by a whale when he was thrown overboard, and there have been tales of dolphins assisting swimmers in distress or shielding them from circling sharks.

Killer whales, however — themselves a species of dolphin — didn’t get their name for nothing. Early Basque whalers called them whale killers when they saw them attacking other whales. Hunting like a pack of wolves, orca know no fear. They’ll tear the throats from grey whale calves, and have even been known to take chunks out of sperm whales — the largest predators that ever lived.

But here’s a sight to gladden the eye. Earlier this year, Californian scientists Robert L Pitman and John W Durban sailed to the Antarctic in search of killer whales. They were looking for a possible new species, known to hunt Weddell seals — one of the plumpest of the pinnipeds (the suborder that includes seals and sea lions) — by washing them off ice floes with their wake.

That’s what was happening here — until a group of humpback whales arrived on the scene. Unlike orca, which are odontocetes or toothed whales, humpbacks are mysticetes, harmless leviathans with only baleen plates in their mouths.

Doubtless open-mouthed themselves, Pitman and Durban — along with a film crew from the BBC Natural History unit — watched as one seal, swept into the water by the orca, swam towards the humpbacks.

As the killer whales moved in, the plucky pinniped leapt on to the vast ribbed belly of a humpback, and nestled in the animal’s armpit. Not only that, but when a wave threatened to return the seal to danger, the humpback used its massive flipper (at five metres, the longest in the animal kingdom) to nudge it back on.

“Moments later the seal scrambled off and swam to the safety of a nearby ice floe,” wrote the scientists. They believe the seal triggered a maternal defence mechanism in the humpbacks. Whatever the truth, it’s a heartening tale. But spare a thought for the orca. They’ve got kids to feed, too.

Baby blue whale and mumThe blue whale is the largest whale or creature ever known to have existed and we are blessed to have these mysterious behemoths still roaming our oceans. The females start having calves when they are between 5 and 10 years of age.
The mother will be pregnant with her baby for at least a year and on giving birth, her new calf will weigh a hefty 3 tons and will measure up to 8 m (25 feet) in length! This big baby also has some appetite on it and will consume the equivalent of a bathtub full of milk daily. This extremely rich and fatty milk (40-50% fat) has the consistency of cottage cheese. The well fed tyke will gain approx. 3.7 kilos an hour with this fat laden feasting.
The burgeoning baby will spend at least the first year of its life with mum and will leave her when large enough to defend itself.It is usually around 13 m when it is ready to venture out on its own.
