Introduction to Long-legged Spiny Lobster

How to identify a Long-legged Spiny Lobster
- Long, slender white-banded walking legs
- Body covered in white spots on a dark reddish-brown ground
- Thick, spiny antennae longer than the body, used as defensive whips
- No pincers at all, unlike clawed lobsters
Why Long-legged Spiny Lobster are interesting
- It has no claws — defence is a set of forward-swept spiny antennae and a violent tail flip.
- Rubbing a plectrum at the base of each antenna against a file makes a rasping noise that works even underwater.
- It spends daylight wedged deep in a reef crevice, often with only antennae showing.
- Its long legs let it cover ground quickly across open reef at night.
- Larvae drift as flat, transparent phyllosoma for months before settling on a reef.

05
Why this diet?
Snails, bivalves, urchins, worms and carrion taken from the reef at night. This diet supports Night Reach because slow-moving prey is only worth walking to when the hunters that would take a lobster are not looking.
06
Activity, rest, and lifespan
Long-legged Spiny Lobsters are strictly nocturnal, resting wedged in crevices through the day and emerging in the hour after dark.
They can live for over a decade, so Night Reach becomes a memorised map — an older lobster knows both the crevices and the routes between them.
07
Long-legged Spiny Lobster reproduction
Females carry thousands of eggs beneath the tail until they hatch into drifting larvae. Offspring fit the principle because the female shelters the whole brood in the same crevice she hides in.
Females carry the eggs and have a small hook on the last pair of legs for grooming them; males are otherwise similar. The difference is functional rather than a display.
