Peacock Flounder (Bothus species)

Peacock flounders live on sandy bottoms near coral reefs. They have flattened bodies with vibrant blue eye-spots. These fish camouflage themselves to ambush prey. Their diet includes small fish and crustaceans. They are solitary and rely on stealth. Conservation status is Least Concern.
Fun Fact: Peacock flounders can change color in seconds.

Pink Sea Star (Pisaster brevispinus)

Pink sea stars inhabit cold Pacific coastal waters. They have thick arms and a soft pink coloration. These echinoderms feed on clams and mussels. They move slowly across the seafloor. Sea stars play an important role in controlling prey populations. Conservation status is Least Concern.
Fun Fact: Sea stars can regenerate lost arms.

Porcupinefish (Diodontidae family)

Porcupinefish inhabit tropical and subtropical oceans. They are round-bodied fish covered with spines that stand erect when inflated. Their powerful jaws crush hard-shelled prey. Porcupinefish are slow-moving and mostly solitary. They are related to pufferfish but have longer spines. Conservation status is Least Concern.
Fun Fact: Porcupinefish can double their size by gulping water.

Pacific Sea Nettle (Chrysaora fuscescens)

This large jellyfish lives along the Pacific coast of North America. It has a golden bell with long, flowing tentacles. Pacific sea nettles feed on plankton and small fish. They drift with currents but can pulse to move slightly. Their sting is mild to humans. Conservation status is Not Evaluated.
Fun Fact: Their tentacles can extend over 4 meters long.

Pencil Urchin (Eucidaris species)

Pencil urchins live on coral reefs in tropical oceans. They have thick, blunt spines rather than sharp ones. These urchins graze on algae and detritus. They hide in crevices during the day. Pencil urchins help maintain reef balance. Conservation status is Least Concern.
Fun Fact: Their spines resemble colored pencils.

Pelagic Thresher Shark (Alopias pelagicus)

This shark inhabits open oceans, especially in tropical waters. It is known for its extremely long tail used to stun prey. Pelagic threshers feed mainly on schooling fish. They are fast and agile swimmers. Overfishing has impacted their populations. Conservation status is Vulnerable.
