Sei Whales (pronounced "say") are named after the Norwegian word for pollock fish, "seje." The Whales and fish moved into fishing areas around the same time. Though their name has Norwegian origins, Sei Whales can actually be found in tropical, temperate, and sub-polar oceans around the world.

Sei Whales are one of the longest whale species, with many individuals not even reaching sexual maturity until they are around 45ft (13m) long. Females are often slightly longer than males. Sei Whales also have the distinction of being one of the fastest swimming cetaceans. They can reach speeds of 35mph (55kph).

Unfortunately, whaling has had a drastic impact on the worldwide Sei Whale population. It is now believed that there around only around 57,000 whales left, which is amazingly few when you consider that during the 1964-65 season nearly 25,000 whales were killed. Nearly 300,000 Sei Whales have been taken since the advent of modern whaling. Sei Whales are now listed on CITES and are protected under the Endangered Species act.

  1. I never even heard of the Sei Whale before. You always have an interesting animal. Some I know and some I don't. I have had such fun going through your archives. I even learned a few things.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a

Four!

For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills.
