Do lobsters feel pain when boiled?

If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.
What percentage of fish survive catch and release?
Many anglers assume that the fish they catch and release survive. But, catch and release does lead to death in fish. The survival rate of released fish depends on the species and how you handle the fish. A survey of over 100 catch and release studies estimates that 16.2 percent of fish die from catch and release.
Do fish remember being caught?
Researchers find that wild cleaner fishes can remember being caught up to 11 months after the fact, and actively try to avoid getting caught again.
