What is the relationship between a pygmy seahorse and a sea fan?

What is the relationship between a pygmy seahorse and a sea fan?

The tiny travelers immediately made themselves at home grasping onto the long waiting sea fans. But then something amazing happened: the sea horses gave birth. Like other seahorses, it is the male pygmy that rears the offspring in his brood pouch, re-releasing groups of offspring every two weeks.

Why do pygmy seahorses camouflage?

Pygmy seahorses are too minuscule and fragile to fend off predators and instead turn to camouflage to survive. Calcium-rich bumps, known as tubercles, cover the seahorses’ bodies and help them blend in with the sea fans’ polyps.

Are pygmy seahorses fast?

They are so well camouflaged that Bargibant’s pygmy seahorse was only discovered after a host gorgonian was collected and observed by marine biologist George Bargibant. Pygmy seahorses grow to an average size of 0.55 to 1.06 inches (1.4 to 2.7 cm).

What adaptation do the pygmy seahorses have?

True pygmy seahorses have two special adaptations for their small size: one gill opening rather than two, and a brood pouch located within the body cavity instead of on the tail.

What do pygmy seahorse do with their tails?

Pygmy sea horses are less than an inch long and are really well camouflaged to match the gorgonian corals they inhabit. These tiny seahorses use their prehensile tails to sturdy themselves and further blend into their surroundings for protection.

Are pygmy seahorses endangered?

Seahorses have unique adaptations that help them survive in the ocean, including the ability to use camouflage, or blend in with their surroundings, and change the color of their body. Long snouts help them find food, and excellent vision and eyes that can move independently are great for avoiding predators.

Why do Pygmy seahorses have a high rate of survival?

Their higher survival rate is thought to be due to them being among the best at hiding in their natural settings – they did after all manage to keep humans in the dark about their existence until 1969!

What is pygmy seahorse camouflage?

The first species discovered lives exclusively on fan corals and matches their colour and appearance. So effective is pygmy seahorse camouflage that it was discovered only when a host gorgonian was being examined in a laboratory.

Do pygmy seahorses lay eggs?

Pygmy seahorses are ovoviviparous, but unlike most animals, the male carries the eggs, which are contained in an on his underside. When mating occurs, the female transfers her eggs into the male’s pouch, where he fertilizes the eggs.

What is dendenise’s pygmy seahorse?

They must live on gorgonian corals but have been found on eight different genera: Acanthogorgia, Annella, Echinogorgia, Ellisella, Melithaea, Muricella, Verrucella and Villogorgia.

What is Severn’s pygmy seahorse?

Severn’s pygmy seahorse ( Hippocampus severnsi) is a free-living species described in 2008.
