The colossal squid is a massive, deep-sea squid of the Southern Ocean. It is so rarely seen that almost everything we know comes from a few specimens and remains found in whales.
Interesting facts
- A colossal squid caught near Antarctica in 2007 weighed about 495 kg.
- Its arms and tentacles have swivelling hooks as well as suckers.
- Sperm whales hunt colossal squid, and their beaks are found in whale stomachs.
- In 2025, scientists filmed a live colossal squid in the deep sea for the first time, a juvenile about 30 cm long.
- The only preserved specimen on public display is at Te Papa museum in New Zealand.
- Adults are heavier but shorter than giant squid.
Behaviour
Scientists think the colossal squid is a slow-moving ambush predator that waits for prey in the dark, rather than chasing it.
Breeding and young
Very little is known about its reproduction.
Threats and conservation
No major threats are known; it is sometimes caught accidentally by deep-sea fishing boats.
