‘Death Ball’ Sponge, Tiny Opossum Among 2025’s Spectacular New Species
The spider with extra-long genitalia (with good reason); A carnivorous caterpillar that eats the body parts of its prey; And a small, mountain-dwelling opossum is one of the spectacular new species described by science in 2025.
A new recent study With approximately 16,000 new species reported to be “discovered” each year, the rate is accelerating – 15 percent of all known species have recently been described in the last 20 years.
“Our good news is that this rate of discovery of new species far exceeds the rate of species extinction, which we calculated to be about 10 per year,” said University of Arizona ecology professor John Wiens, who co-authored the study. in a news release,
Many are not really new discoveries. In many cases, they were known or photographed locally, or were collected for museums many years earlier. They had never been identified and described by science until now.
But scientists say this official documentation step is important. “If we don’t know a species exists, we can’t protect it from extinction,” Wiens said.
This is a great way for us to learn about some interesting and unique creatures that we have never seen or heard of before. Here’s a closer look at some of them.
well endowed tarantula
Four new species of tarantula discovered in the Horn of Africa and the Arabian Peninsula. What is special about them? Well, their males have the longest genitalia of all known tarantulas.
The largest species, namely satyrex feroxThe foot span is 14 centimeters (about the width of a slice of bread). But if you haven’t been impressed yet, males have genitalia called palps that are up to five centimeters long; This is almost as long as their longest legs.
Alireza Zamani, a researcher at the University of Turku who led the study describing the new tarantula, suggests that the long palps “may allow the male to maintain a safe distance during mating to help him avoid being attacked and eaten by a highly aggressive female.”
The caterpillar is wearing a scary outfit
Most caterpillars are herbivorous, but this year scientists in Hawaii found one that lives in spider webs, eats prey trapped in the web, and then weaves their body parts into a coat or covering around its body (which then becomes its cocoon).
Unique “bone collector” caterpillar, which transforms into a moth with feathery wings, was described in science In April. It has only been found in a small patch of 15 square kilometers of forest in the Wai’ane mountain range on O’ahu, suggesting it is endangered.

Carnivorous ‘death-ball’ sponge
The deep ocean is a part of the planet that has been little explored by humans, and each expedition there uncovers many new and surprising species. In October, the Nippon Foundation-Nekton Ocean Census 30 new species announced Discovered in the Southern Ocean near Antarctica.
They include the “death-ball” sponge, which does not filter feed like most sponges, but instead has shells covered with small hooks to trap prey. New sea star species and an armoured, iridescent scale worm are also on the list.
Eggy Sea Slug
The shallow waters also yielded some beautiful and unique new species, including a sea slug that looks like it’s covered in fried eggs, named Phyllidia ovata. This wart is one of two beautiful new species of sea slugs that hunt sponges and steal their toxins for self-defense.
Their bright colors warn potential predators that they are poisonous. The new species was photographed 23 years ago by divers in North Sulawesi, Indonesia, but only described by science This past July.
New Canadian Crayfish
The aquatic creature was one of the new species discovered in Canada this year. okanagan crayfish Found in BC’s Okanagan Lake. It was previously mistaken for the common, similar-looking signal crayfish. The distinguishing feature of the new species is that it lacks the distinctive white markings found on the claws of signal crayfish.
Unfortunately, the new species is considered endangered, and scientists are especially concerned because Okanagan Lake is heavily used by humans.
New bats discovered by Canadians
Canadian researchers were also involved in the discovery of six small new species of tube-nosed bats in the Philippines.
Judith Eggar and Burton Lim of the Royal Ontario Museum Co-authored a study describing the species Just before Halloween. Each bat, weighing only four to 14 grams, was collected during expeditions by researchers in the Philippines and the Field Museum of Chicago over the past 30 years.
Crocodile Hunter Snake, Pinocchio Lizard
Every year some new species are named after real or fictional famous characters. There are two reptiles with famous names this year Long-nosed Pinocchio chameleon of Madagascar and a New wolf snake from Great Nicobar Island, Indiahas been named Lycodon erwini After the late Steve Irwin’s star crocodile hunter TV series.
small mouse opossum
Here’s one of the less scary animals on this year’s list: a small, spectacled marsupial found in the Peruvian Andes in 2018. small mouse opossum Marmosa Chachapoya It is rat-sized (about 10 cm tall, with a 15 cm tail) and lives at much higher altitudes than other rats. It was described in June in the journal American Museum Newbie,
toads without tadpoles
We don’t have any amphibians on our list yet, so let’s add a few before we go.
Three unusual species discovered this year include toads that live in trees away from water in Tanzania’s Eastern Arc Mountains. This makes the tadpole stage of their life cycle a challenge – so they abandon it and give birth to live toadlets.
“Survivalism is exceptionally rare among frogs and toads, with less than one percent of frog species practicing it, making these new species exceptionally interesting,” H. Christoph Liedtke saidA researcher at the Spanish National Research Council, who co-authored Description of the new species in November.
The new species was identified through physical and genetic analysis of museum specimens that were originally thought to be the same species. Two of the new species are already believed to be critically endangered.
