Questions & Answers

Q: How do electric rays use their electric shock to catch prey?

Electric rays use modified gill muscles to generate electric shocks, stunning and immobilizing their prey before consuming them. The electric shocks can also be deadly to humans if they come into contact with the rays.

Q: How does the venom of the blue-ringed octopus work?

The venom of the blue-ringed octopus contains tetrodotoxin, which paralyzes the nervous system of its prey. If a human gets stung, the venom can quickly lead to paralysis and even death.

Q: Why do spiny lobsters form a protective group during fall storms?

Spiny lobsters, typically shy scavengers found hiding in cracks and crevices, are forced out into the open during fall storms. By forming a large group, they provide protection to each other from predators and capitalize on the opportunity to scavenge on dead prey.

Q: How does the stonefish use its poison-tipped spines to catch prey?

The stonefish camouflages itself as an ordinary rock and waits for unsuspecting prey to come near. When the prey is within range, the stonefish strikes with its spines, injecting a mix of neurotoxins and myotoxins that paralyze and kill the prey.
