This next shark goes by two common names: the “dusky smoothhound” or the “smooth dogfish.” But don’t worry, its scientific name, Mustelus canis, stays the same! As part of the Triakidae family, this species of houndshark is olive grey to brown in colour, splattered with yellow or grey-white shades throughout.
Females live longer than males, with 16 years against to their 10 years. They can get up to 1.5 m (5 ft) in length, with a maximum weight of 12 kg (27 lbs). Unlike some sharks, they are a fast-growing shark and the first shark to be recognized as having viral infections!
The hooktooth dogfish (Aculeola nigra) is… an interesting looking shark. With a blunt, flattened snout and very large eyes as you can tell from the picture it isn’t what some would call “beautiful” or “handsome.” They have small, grooved spines on their dorsal fins, and have a broad caudal fin.
This past week I turned 24 (holy guacamole) and I wanted to share a few things that happened this year that... I didn't see coming. And I'm hoping that these lessons I learned hopefully help some of you who are reading this.
But first, a big thank you to all the readers who reached out to wish me a happy birthday! I truly appreciate you taking the time to wish me a happy day- and it was just that. A wonderful day surrounded by friends and looking towards the future!
