`Strange bedfellow frogs' (part I): rotund, adorable brevicipitids

`Strange bedfellow frogs' (part I): rotund, adorable brevicipitids

Suddenly and unexpectedly, I have the urge to write about frogs. Today we look briefly at the first of two behaviourally peculiar, anatomically surprising groups, both of which are endemic to sub-Saharan Africa, both of which belong to a major neobatrachian frog clade called Allodapanura, and both of which have been united in a clade [...]..

Ocean Giants (Actual Size)

Just how big is a giant squid? Not quite as big, perhaps, as you might think. This fabulous new graphic from the Deep Sea News crew and several other scientists represents *a lot* of research to find out the true largest sizes of 25 ocean creatures of giant repute...

Giving Birth To A Tropical Parasite [Video Not For The Squeamish]

“Why is it that an animal that is actively trying to kill us, such as a lion, gets more respect than one that is only trying to nibble on us a little, without causing much harm?” -Piotr Naskrecki Biologist Piotr Naskrecki, who traveled with me to Belize last year, returned home to find himself incubating [...]..

There Is So Much More to Flying Frogs Than Flying

Episode 2 of David Attenborough's Conquest of the Skies appeared on TV the other day, and I watched it (in fact, I livetweeted throughout, mostly because I wanted to talk about their portrayal of pterosaurs and Mesozoic theropods)...

Gladiatorial glassfrogs, redux

Readers with supernaturally good memories might remember the two articles, published here back in January and February 2013, on glassfrogs, a highly unusual and poorly known group of Neotropical frogs, so named due to their incredible translucent or transparent ventral skin...

Troublemaker Lee Smolin Says Physics—and Its Laws—Must Evolve*

Troublemaker Lee Smolin Says Physics–and Its Laws–Must Evolve*

What separates good from bad troublemakers? Productive provocateurs from mere contrarians, bullshit artists, attention-seekers? This is the personalized equivalent of philosophy’s demarcation problem, which involves telling genuine from pseudo-science...

Tadpole nests, past and present

Thanks to that recent Tet Zoo article about American spadefoot toads and their tadpoles, I've had visions in my mind of drying ephemeral pools in hot, arid environments, crammed with crowded, gasping tadpoles...

Megophrys: so much more than Megophrys nasuta

In the previous article, we looked at parsley frogs or pelodytids - a small and conservative lineage within the anuran clade Pelobatoidea (also known as Anomocoela, and commonly as the spadefoot toads)...

Octopus Genome Remains Elusive—But Full of Promise

As many mysteries as the octopus holds—its comprehensive camouflage, smart suckers, agile brain—its genome is surely holding many more (including how it can regenerate its arms—suckers, nerves and all)...

Will We Find Extraterrestrial Life In 2015?

Will We Find Extraterrestrial Life In 2015?

Probably not, but just possibly yes. One of the reasons that the search for life elsewhere in the universe is so exciting is that it would take only one chance discovery, one lucky break, for all the walls to come tumbling down...

Parsley frogs: spadefoots without spades

Parsley frogs: spadefoots without spades

Anurans - frogs and toads - haven't received enough coverage on Tet Zoo of late, so here's one of several efforts to redress the balance. For no particular reason, in this article I want to talk about pelobatoids, also known as anomocoelans: the anuran group that (as conventionally conceived) includes spadefoot toads (Pelobatidae) and parsley [...]..
