Finding that perfect Father's Day gift can be a real nightmare. Socks? Too boring. A tie? He'll never wear it. Slippers? He already has three pairs. If Father's Day existed in the animal kingdom, the challenge would be even more difficult. What do you get for the seahorse dad that has it all? Never fear - we've got some suggestions.

Fatherly Freight

Put your back into it, dad.

When it comes to daddy duty, giant water bugs really know how to put their backs into it. A female will actually 'glue' her eggs (as many as 150 of them!) onto her mate's back – and he'll diligently haul that precious cargo around until hatching time, protecting it from predators, and regularly cleaning and aerating the eggs to keep them healthy. Weeks before the eggs hatch, dad will even stop eating ... just to avoid the temptation of snacking on his cargo. What's the prefect gift to help him out with all of this fatherly freight? A handy little egg cart!

Bun in the oven

When it comes to bringing forth the next generation, it's the male seahorse who does most of the work.

Seahorse dads certainly take the reins when it comes to parenting. Male seahorses carry up to 2,000 fertilised eggs in a special pouch before 'giving birth' to the babies (called fry). The eggs develop inside the dad for 10-25 days – much like they would during a pregnancy! When the tiny seahorses are ready to be born, the male actually undergoes muscular contractions to expel them. It's time to give back to these devoted dads … with a much-deserved pair of pregnancy pants!

Safe in storage

What better gift than mouthwash for a dad that swallows his babies? Don’t panic yet … when the giant African bullfrog gulps down his young, it's for their own good. Thousands of fertilised eggs are stored in the male frog's large vocal sac (for safekeeping). After six weeks 'in storage', the babies are spat out into the bright, beautiful world for the first time!

Eggs on ice

The noble feet of fatherhood.

Keeping eggs on ice is risky business, but emperor penguins have found a solution to the incubation equation. Each winter, thousands of male penguins pop recently laid eggs onto their scaly feet, which keeps them off the frozen ground below. A fold of skin on the birds' abdomen covers the eggs, offering additional warmth. During the two-month incubation, the male penguins will not eat – and must sleep most of the time to conserve energy. Once the eggs hatch, the chicks will stay cozily on their fathers' feet for 7-8 weeks … so this Father's Day, it's time to reward those tired penguin toes with a nice foot-spa soak.
