Deep-sea gigantism really exists.
In zoology, abyssal gigantism represents the tendency for species of invertebrates and other deep-sea dwelling animals to be larger than their shallower-water relatives. And I bet Fukushima is now helping creating monster-like creatures even more impressive than those shown below:
A Japanese spider crab whose outstretched legs measured 12 ft (3.7 m) across:
A robust clubhook squid, whose mantle reaches 2 m (6.6 ft) in length, caught off Alaska.
A 7-meter-long (23 ft) king of herrings oarfish caught off California
Bathynomus giganteus may reach up to 0.76 metres (2.5 ft) in length:
A huge Colossendeis colossea sea spider:
Food scarcity, lower temperatures, and reduced predation pressures are all considered to be contributing factors to deep-sea gigantism. And let’s add radiation to this small list.
